It consists of two wires of dissimilar metals joined near the measurement point. The output is a small voltage measured between the two wires.While appealingly simple in concept, the theory behind the thermocouple is subtle, the basics of which need to be understood for the most effective use of the sensor.Thermocouple theoryA thermocouple circuit has at least two junctions: the measurement junction and a reference junction. Typically, the reference junction is created where the two wires connect to the measuring device. This second junction it is really two junctions: one for each of the two wires, but because they are assumed to be at the same temperature (isothermal) they are considered as one (thermal) junction. It is the point where the metals change - from the thermocouple metals to what ever metals are used in the measuring device - typically copper.The output voltage is related to the temperature difference between the measurement and the reference junctions. This is phenomena is known as the Seebeck effect. (See the Thermocouple Calculator to get a feel for the magnitude of the Seebeck voltage). The Seebeck effect generates a small voltage along the length of a wire, and is greatest where the temperature gradient is greatest. If the circuit is of wire of identical material, then they will generate identical but opposite Seebeck voltages which will cancel. However, if the wire metals are different the Seebeck voltages will be different and will not cancel.In practice the Seebeck voltage is made up of two components: the Peltiervoltage generated at the junctions, plus the Thomson voltage generated in the wires by the temperature gradient.The Peltier voltage is proportional to the temperature of each junction while the Thomson voltage is proportional to the square of the temperature difference between the two junctions. It is the Thomson voltage that accounts for most of the observed voltage and non-linearity in thermocouple response.Each thermocouple type has its characteristic Seebeck voltage curve. The curve is dependent on the metals, their purity, their homogeneity and their crystal structure. In the case of alloys, the ratio of constituents and their distribution in the wire is also important. These potential inhomogeneous characteristics of metal are why thick wire thermocouples can be more accurate in high temperature applications, when the thermocouple metals and their impurities become more mobile by diffusion.The practical considerations of thermocouplesThe above theory of thermocouple operation has important practical implications that are well worth understanding:1. A third metal may be introduced into a thermocouple circuit and have no impact, provided that both ends are at the same temperature. This means that the thermocouple measurement junction may be soldered, brazed or welded without affecting the thermocouple's calibration, as long as there is no net temperature gradient along the third metal.Further, if the measuring circuit metal (usually copper) is different to that of the thermocouple, then provided the temperature of the two connecting terminals is the same and known, the reading will not be affected by the presence of copper.2. The thermocouple's output is generated by the temperature gradient along the wires and not at the junctions as is commonly believed. Therefore it is important that the quality of the wire be maintained where temperature gradients exists. Wire quality can be compromised by contamination from its operating environment and the insulating material. For temperatures below 400°C, contamination of insulated wires is generally not a problem. At temperatures above 1000°C, the choice of insulationand sheath materials, as well as the wire thickness, become critical to the calibration stability of the thermocouple.The fact that a thermocouple's output is not generated at the junction should redirect attention to other potential problem areas.3. The voltage generated by a thermocouple is a function of the temperature difference between the measurement and reference junctions. Traditionally the reference junction was held at 0°C by an ice bath:The ice bath is now considered impractical and is replace by a reference junction compensation arrangement. This can be accomplished by measuring the reference junction temperature with an alternate temperature sensor (typically an RTD or thermistor) and applying a correcting voltage to the measured thermocouple voltage before scaling to temperature.The correction can be done electrically in hardware or mathematically in software. The software method is preferred as it is universal to all thermocouple types (provided the characteristics are known) and it allows for the correction of the small non-linearity over the reference temperature range.4. The low-level output from thermocouples (typically 50mV full scale) requires that care be taken to avoid electrical interference from motors, power cable, transformers and radio signal pickup. Twisting the thermocouple wire pair (say 1 twist per 10 cm) can greatly reduce magnetic field pickup. Using shielded cable or running wires in metal conduit can reduce electric field pickup. The measuring device should provide signal filtering, either in hardware or by software, with strong rejection of the line frequency (50/60 Hz) and its harmonics.5. The operating environment of the thermocouple needs to be considered. Exposure to oxidizing or reducing atmospheres at high temperature can significantly degrade some thermocouples. Thermocouples containing rhodium (B,R and S types) are not suitable under neutron radiation.The advantages and disadvantages of thermocouplesBecause of their physical characteristics, thermocouples are the preferred methodof temperature measurement in many applications. They can be very rugged, are immune to shock and vibration, are useful over a wide temperature range, are simple to manufactured, require no excitation power, there is no self heating and they can be made very small. No other temperature sensor provides this degree of versatility.Thermocouples are wonderful sensors to experiment with because of their robustness, wide temperature range and unique properties.On the down side, the thermocouple produces a relative low output signal that is non-linear. These characteristics require a sensitive and stable measuring device that is able provide reference junction compensation and linearization.Also the low signal level demands that a higher level of care be taken when installing to minimise potential noise sources.The measuring hardware requires good noise rejection capability. Ground loops can be a problem with non-isolated systems, unless the common mode range and rejection is adequate.Types of thermocoupleAbout 13 'standard' thermocouple types are commonly used. Eight have been given an internationally recognised letter type designators. The letter type designator refers to the emf table, not the composition of the metals - so any thermocouple that matches the emf table within the defined tolerances may receive that table's letter designator.Some of the non-recognised thermocouples may excel in particular niche applications and have gained a degree of acceptance for this reason, as well as due to effective marketing by the alloy manufacturer. Some of these have been given letter type designators by their manufacturers that have been partially accepted by industry.Each thermocouple type has characteristics that can be matched to applications. Industry generally prefers K and N types because of their suitability to high temperatures, while others often prefer the T type due to its sensitivity, low cost and ease of use.A table of standard thermocouple types is presented below. The table also showsthe temperature range for extension grade wire in brackets.Accuracy of thermocouplesThermocouples will function over a wide temperature range - from near absolute zero to their melting point, however they are normally only characterized over their stable range. Thermocouple accuracy is a difficult subject due to a range of factors. In principal and in practice a thermocouple can achieve excellent results (that is, significantly better than the above table indicates) if calibrated, used well below its nominal upper temperature limit and if protected from harsh atmospheres. At higher temperatures it is often better to use a heavier gauge of wire in order to maintain stability (Wire Gauge below).As mentioned previously, the temperature and voltage scales were redefined in 1990. The eight main thermocouple types - B, E, J, K, N, R, S and T - were re-characterised in 1993 to reflect the scale changes. (See: NIST Monograph 175 for details). The remaining types: C, D, G, L, M, P and U appear to have been informally re-characterised.Try the thermocouple calculator. It allows you the determine the temperature by knowing the measured voltage and the reference junction temperature.Thermocouple wire gradesThere are different grades of thermocouple wire. The principal divisions are between measurement grades and extension grades. The measurement grade has the highest purity and should be used where the temperature gradient is significant. The standard measurement grade (Class 2) is most commonly used. Special measurement grades (Class 1) are available with accuracy about twice the standard measurement grades.The extension thermocouple wire grades are designed for connecting the thermocouple to the measuring device. The extension wire may be of different metals to the measurement grade, but are chosen to have a matching response over a much reduced temperature range - typically -40°C to 120°C. The reason for using extension wire is reduced cost - they can be 20% to 30% of the cost of equivalent measurementgrades. Further cost savings are possible by using thinnergauge extension wire and a lower temperature rated insulation.Note: When temperatures within the extension wire's rating are being measured, it is OK to use the extension wire for the entire circuit. This is frequently done with T type extension wire, which is accurate over the -60 to 100°C range.Thermocouple wire gaugeAt high temperatures, thermocouple wire can under go irreversible changes in the form of modified crystal structure, selective migration of alloy components and chemical changes originating from the surface metal reacting to the surrounding environment. With some types, mechanical stress and cycling can also induce changes.Increasing the diameter of the wire where it is exposed to the high temperatures can reduce the impact of these effects.The following table can be used as a very approximate guide to wire gauge:At these higher temperatures, the thermocouple wire should be protected as much as possible from hostile gases. Reducing or oxidizing gases can corrode some thermocouple wire very quickly. Remember, the purity of the thermocouple wire is most important where the temperature gradients are greatest. It is with this part of the thermocouple wiring where the most care must be taken.Other sources of wire contamination include the mineral packing material and the protective metal sheath. Metallic vapour diffusion can be significant problem at high temperatures. Platinum wires should only be used inside a nonmetallic sheath, such as high-purity alumna.Neutron radiation (as in a nuclear reactor) can have significant permanent impact on the thermocouple calibration. This is due to the transformation of metals to different elements.High temperature measurement is very difficult in some situations. In preference, use non-contact methods. However this is not always possible, as the site of temperature measurement is not always visible to these types of sensors.Colour coding of thermocouple wireThe colour coding of thermocouple wire is something of a nightmare! There are at least seven different standards. There are some inconsistencies between standards, which seem to have been designed to confuse. For example the colour red in the USA standard is always used for the negative lead, while in German and Japanese standards it is always the positive lead. The British, French and International standards avoid the use of red entirely!Thermocouple mountingThere are four common ways in which thermocouples are mounted with in a stainless steel or Inconel sheath and electrically insulated with mineral oxides. Each of the methods has its advantages and disadvantages.Sealed and Isolated from Sheath: Good relatively trouble-free arrangement. The principal reason for not using this arrangement for all applications is its sluggish response time - the typical time constant is 75 secondsSealed and Grounded to Sheath: Can cause ground loops and other noise injection, but provides a reasonable time constant (40 seconds) and a sealed enclosure.Exposed Bead: Faster response time constant (typically 15 seconds), but lacks mechanical and chemical protection, and electrical isolation from material being measured. The porous insulating mineral oxides must be sealedExposed Fast Response: Fastest response time constant, typically 2 seconds but with fine gauge of junction wire the time constant can be 10-100 ms. In addition to problems of the exposed bead type, the protruding and light construction makes the thermocouple more prone to physical damage.Thermocouple compensation and linearizationAs mentioned above, it is possible to provide reference junction compensation in hardware or in software. The principal is the same in both cases: adding a correction voltage to the thermocouple output voltage, proportional to the reference junction temperature. To this end, the connection point of the thermocouple wires to the measuring device (i.e. where the thermocouple materials change to the copper of thecircuit electronics) must be monitored by a sensor. This area must be design to be isothermal, so that the sensor accurately tracks both reference junction temperatures.The hardware solution is simple but not always as easy to implement as one might expect.The circuit needs to be designed for a specific thermocouple type and hence lacks the flexibility of the software approach.The software compensation technique simplifies the hardware requirement, by eliminating the reference sensor amplifier and summing circuit (although a multiplexer may be required).The software algorithm to process the signals needs to be carefully written. A sample algorithm details the process.A good resource for thermocouple emf tables and coefficients is at the US Commerce Dept's NIST web site. It covers the B, E, J, K, N, R, S and T types.The thermocouple as a heat pumpThe thermocouple can function in reverse. If a current is passed through a thermocouple circuit, one junction will cool and the other warm. This is known as the Peltier Effect and is used in small cooling systems. The effect can be demonstrated by alternately passing a current through a thermocouple circuit and then quickly measuring the circuit's Seebeck voltage. This process has been used, with very fine thermocouple wire (0.025 mm with about a 10 mA current), to measure humidity by ensuring the cooled junction drops below the air's dew point. This causes condensation to form on the cooled junction. The junction is allowed to return to ambient, with the temperature curve showing an inflection at the dew point caused by the latent heat of vaporization.Measuring temperature differencesThermocouples are excellent for measuring temperatures differences, such as the wet bulb depression in measuring humidity. Sensitivity can be enhanced by constructing a thermopile - a number of thermocouple circuits in series.In the above example, the thermopile output is proportional to the temperaturedifference T1 - T2, with a sensitivity three times that of a single junction pair. In practice, thermopiles with two to hundreds of junctions are used in radiometers, heat flux sensors, flow sensors and humidity sensors. The thermocouple materials can be in wire form, but also printed or etched as foils and even electroplated.An excellent example of the thermopile is in the heat flux sensors manufactured by Hukseflux Thermal Sensors. Also see RdF Corp. and Exergen Corp.The thermocouple is unique in its ability to directly measure a temperature difference. Other sensor types require a pair of closely matched sensors to ensure tracking over the entire operational temperature range.The thermoelectric generatorWhile the Seebeck voltage is very small (in the order of 10-70μV/°C), if the circuit's electrical resistance is low (thick, short wires), then large currents are possible (e.g. many amperes). An efficiency trade-off of electrical resistance (as small as possible) and thermal resistance (as large as possible) between the junctions is the major issue. Generally, electrical and thermal resistances trend together with different materials. The output voltage can be increased by wiring as a thermopile.The thermoelectric generator has found its best-known application as the power source in some spacecraft. A radioactive material, such as plutonium, generates heat and cooling is provided by heat radiation into space. Such an atomic power source can reliably provide many tens of watts of power for years. The fact that atomic generators are highly radioactive prevents their wider application.译文:热电偶温度传感器热电偶的定义热电偶是最简单的传感器之一。

TT302 温度变送器概述TT302温度变送器接收毫伏(mV)输出的信号,这类传感器包括热电偶或阻性传感器,例如:热电阻(RTD)。

它所接受的信号必须在允许的输入范围之内。

允许输入电压范围为-50到500,电阻范围为0到2000欧姆。

功能描述-硬件每个板的功能介绍如下:图2.1 TT302-硬件构成方框图多路转换器多路转换器将变送器端子接到相应信号调理板上,以保证在正确的端子上测量电压。

信号调理板他的作用给输入信号提供一个正确的值以满足A/D转换。

A/D转换器A/D转换器将输入信号转换成数字形式传给CPU。

信号隔离他的作用在输入和CPU之间隔离控制信号和数字信号。

中央处理单元(CPU)RAM PROM和EEPROMCPU是变送器的智能部分,主要完成测量,板的执行,自诊断和通信的管理和运行。

系统程序存储在PROM中。

RAM用于暂时存放运算数据。

在RAM中存放的数据一旦断电立即消失,所以数据必须保存在不易丢失的EEPROM中。

例如:标定,块的标识和组态等数据。

通信控制器监视在线动态,调整通信信号,插入,删除预处理,滤波。

电源变送器电路通过现场总线电源供电。

电源隔离像信号隔离一样,供给输入部分的信号必须要隔离,电源隔离采用变压器将直流供电电源转换成高频交流供电。

显示控制器从CPU接收数据送给LCD显示器的显示部分,此时显示器必须处于打开状态。

本机调整它有两个磁性驱动开关,它们必须由磁性工具来驱动而不是机械或电的接触。

图2.2-LCD指示器温度传感器TT302像前面所描述的那样,可以兼容多种类型的传感器。

TT302为使用热电偶或热电阻RTD 测量温度进行了特殊设计。

此类传感器的基本内容如下所述:热电偶热电偶由两种不同的金属或合金在一端连接在一起所组成的,被称为测量端或热端。

测量端必须放在测量点上,热电偶的另一端是打开的连接在温度变送器上,这一端称做参考端或冷端。

在大多数应用中,塞贝克效应可以充分解释热电偶的工作原理。

热电偶是如何工作的(塞贝克效应)当金属丝的两端有温差时,在金属丝的没一端都会产生一个小的电动势,这种现象就叫做塞贝克效应。

当两种不同金属丝连接在一起,而另一端开放时,两端之间的温差将会产生一个电压输出。

现在,有两个重要的问题需要注意:首先,热电偶所产生的电压与测量端和冷端的温度成比例,因此,为了得到被测温度必须加上参考端的温度,被称做冷端温度补偿。

TT302可以自动进行补偿。

为此,在TT302传感器端子装有一个温度传感器。

其次,如果热电偶与变送器端子之间的导线没有采用与热电偶相同的导线(例如:由热电偶传感器或接线盒到变送器端子之间采用铜线)那么就会对温度测量产生影响,因此必须要进行冷端补偿。

热电偶的电势在冷端温度为0℃时与热端温度的关系用热电偶分度表来表示。

分度表存储在TT302的存储器中,他们是国际标准NBS(B,E,J,K,N,R,S,T)和德国工业标准DIN(L,U) 热电阻(RTD)热电阻通常被称做RTD,它的工作原理是金属的阻抗会随着温度的升高而增加,存储在TT302的中的热电阻分度表有日本工业标准JIS[1604-81] (Pt50,Pt100)。

国际电工委员会IEC,DIN,JIS[1604-89] (Pt50,Pt100&Pt500),通用电气公司GE(Cu10)和DIN(Ni120)。

为使热电阻能够正确测量温度,必须消除传感器到测量电路之间线路电阻所造成的影响。

在一些工业应用中,这些导线有几百米长,在环境温度变化剧烈的场所,消除线路电阻的影响是极为重要的。

TT302允许二线制连接,但可能会引起测量误差。

此误差取决于接线的长度和导线经过处的温度(图2.3二线制连接)在二线制连接中,电压U2与热电阻的阻值R TD和导线的电阻R成正比U2=(R TD+2R X I图2.3二线制连接为了避免导线电阻的影响,推荐用三线制连接(图2.4三线制连接)或四线制连接(图2.5三线制连接)在三线制连接中,端子3是高阻抗输入端,因此,没有电流流过该导线,此导线上也没有压降。

电压U2-U1与电阻无关,因为导线电阻上的电压被抵消掉了,它仅与R TD的电阻有关。

U2-U1=(R TD+R)X I-RxI=R TDx I图2.4 三线制连接在四线制连接中,端子2和端子3是高阻抗输入端,因此,没有电流流过此端,也没有压降产生。

另外两根导线的电阻可不予考虑,这两根导线上也没有测量点,因此电压U2只与R TD电阻值有关U2=R TDx I图2.5四线制连接双通道连接和二线制连接相似,也存在相同的问题(图2.6双通道连接)导线的电阻需要测量,而且在同一温度下测量也不能忽略他们的阻值,因为长度也会影响使它们不同。

蒸汽过热是中心电站所采用的设计特点之一,过热增加了整体循环效率。

另外,它降低了汽轮机末级叶片的湿度,因此提高了汽机的内在效率。

一般而言,过热器可分为辐射式过热器、对流式过热器或联合式过热器,这取决于热量是怎样从烟气传给蒸汽的。

这些过热器具有不同的运行特性,在机组负荷的宽范围内如能保持出口汽温不变,这样的特性是最希望的。

当出口汽温变得过高,则会引起过热器因部分过热而失效。

对流过热器位于炉膛出口,或能够从燃烧的高温产物吸收热能的区域。

对流过热器常常通过一束水冷管来遮蔽炉膛辐射热。

当这些管子留有足够的间隔时,也能遮断渣粒而减少过热器上的结渣问题。

在大型蒸汽发生器系统中,对流过热器常常分为两部分:一级过热器和二级过热器。

饱和蒸汽首先进入一级过热器而接受初始过热,一级过热器为于相对低的烟温区,在部分过热后,蒸汽进到二级过热器而完成其过热过程。

使过热器分为两级的主要原因是为蒸汽再热器提供一个空间,使烟气向蒸汽有效传热。

辐射过热器没有对流过热器那样得到普遍使用。

当需要辐射过热器时,它通常位于炉膛壁上代替一端水冷管。

另一种布置是使辐射过热器刚好在屏式管后面,辐射过热器是二级过热器的中间部分。

中心电站锅炉提供蒸汽再热。

再热器一般是对流式,且通常位于一级与二级过热器之间的空间。

当蒸汽温度在汽机中部分膨胀后,它返回锅炉再热。

离开再热器的蒸汽温度通常等于过热蒸汽温度。

因为再热器的设计在运行本质上与过热器一样,过热器的讨论将同样适用于再热器。

在过热器的热力设计中,首先确定蒸汽温度。

一般而言这点在电站系统设计中完成,以平衡电站初始费用和服役期运行费用。

近年来,对于所有蒸汽发生器系统,最佳蒸汽温度约538℃。

热力设计中的第二步是近似确定所要求的过热器面积数量。

在过热器表面积被确定后,下一步要考虑的是选择管子的长度、管径和管子数。

显然,选择是一个反复的过程,先产生一个尝试解,查看其各种约束是否满足,从各种可接受解中找到最优解。

最佳过热器应该有给予设计汽温所必需的足够的传热表面。

管子参数(长度和直径)使得蒸汽压降和管子金属温度将不超过设计值。

管子金属温度是一个重要参数,对管子材料的选择有很大影响。

另外,最佳过热器要使管子布置得使所产生的灰和渣最少。

现代过热器有许多管子通道,管子都顺排布置而不用错排布置。

管子通常是圆管,外径为5或6.3cm。

没有附在管子上的扩展表面(如肋片),材料的选择取决于蒸汽温度和压力。

碳钢的允许温度达430℃,常常用于低温过热器。

铬-钼钢、不锈钢或某种类似的耐热合金能承受高达650℃的温度,因而它们被选做高温区过热器。

温度调节与控制对过热器与再热器都很重要,蒸汽温度调节常常要在锅炉指定的时间内进行,原则方法是增加或减少传热面积。

蒸汽温度也可以通过调节热烟气温度和质量流量来实现。

一般而言,这些都是通过改变过量空气或者蒸发段效果来完成。

在锅炉运行中,有许多因素影响离开过热器和再热器的蒸汽温度,它们包括锅炉负荷、过量空气、给水温度和受热面的清洁度。

运行中蒸汽温度的控制必须在不改变设备布置的情况下完成,最有效的措施包括:烟气旁路,燃烧器控制,温度调节,烟气再循环,过量空气以及分隔炉膛。

烟气旁路是控制烟气流过过热器的流量,这种方法是主要缺点是高温区可动闸板操作运行困难,且对负荷变化响应慢。

燃烧器控制通常是控制火焰位置和燃烧速度,使燃烧器倾斜可以使火焰指向或离开过热器,这将改变炉膛的吸热和过热器的烟气温度。

随着锅炉负荷减小,燃烧器将逐一推出运行,这将改变燃烧速度,从而改变流经过热器的烟气流量。

温度调节是常使用的方法之一,温度调节器通常位于一级和二级过热器之间。

有两种基本形式的温度调节器:一种是管式,一部分过热蒸汽通过换热器管道,将热量传给锅炉水(可以是锅炉给水或锅炉汽包水),随后进入温度调节,从一级过热器分开的蒸汽将会合,一起进入二级过热器;第二种温度调节器是将给水喷入过热蒸汽流中。

给水蒸发使蒸汽温度降低,控制给水量就可以控制蒸汽温度。

必须注意要使喷水足够纯净,喷水要和过热蒸汽很好地混合,从而使得第二级过热器的入口没有水滴。

烟气再循环通常采用改变炉膛和过热器的吸收率来控制蒸汽温度,当需要蒸汽温度声高时,从省煤器出口取出的一部分烟气将循环返回炉膛底部。

因此,炉膛温度降低,导致炉膛吸热减少,而炉膛出口烟温升高。

这么高的烟温,加上烟气流量增加,将增加过热器的传热速率,使蒸汽出口温度升高。

温度控制也受所使用的过量空气量的影响,过量空气越多,蒸汽出口温度将越高,其原因与烟气再循环方法的原因类似。

必须指出,太多的过量空气将导致锅炉燃烧效率降低。

分隔炉膛锅炉是将饱和蒸汽的生产安排在一段,而将过热蒸汽的生产安排在另一段。

过热汽温是通过控制两个炉膛中的燃烧速率来调节的,这一方法不经济,很少应用中心电站锅炉。

The criterion is that the signal is within the range of the input. For mV, the range is -50 to 500mV and for resistance, 0-2000 Ohm.Functional Description – HardwareThe function of each block is described below.Figure 2.1—TT302Block DiagramMUX MultiplexerThe MUX multiplexes the sensor terminals to the signal conditioning section ensuring that the voltages are measured between the correct terminals.Signal ConditionerIts function is to apply the correct gain to the input signals to make them suit the A/D -converter. A/D ConverterThe A/D converts the input signal to a digital format for the CPU.Signal IsolationIts function is to isolate the control and data signal between the input and the CPU.(CPU) Central Processing Unit, RAM, PROM and EEPROMThe CPU is the intelligent portion of the transmitter, being responsible for the management and operation of measurement, block execution, self-diagnostics and communication. The program is stored in a PROM. For temporary storage of data there is a RAM. The data in the RAM is lost if the power is switched off. However there is a nonvolatile EEPROM where data that must be retained is stored. Examples, of such data are trim, calibration, block configuration andidentification data.TT302 - Fieldbus Temperature TransmitterCommunication ControllerIt monitors line activity, modulates and demodulates communication signals and inserts and deletes start and end delimiters.Power SupplyTakes power of the loop-line to power the transmitter circuitry.Power IsolationJust like the signals to and from the input section, the power to the input section must be isolated. Isolation is achieved by converting the DC supply into a high frequency AC supply and galvanically separating it using a transformer.Display ControllerReceives data from the CPU informing which segments of the Liquid Crystal Display, should be turned on.Local AdjustmentThere are two switches that are magnetically activated. They can be activated by the magnetic tool without mechanical or electrical contact.Figure 2.2 - LCD IndicatorTemperature SensorsThe TT302, as previously explained, accepts several types of sensors. The TT302 is specially designed for temperature measurement using thermocouples or Resistive Temperature Detectors (RTDs).Some basic concepts about these sensors are presented below.ThermocouplesThermocouples are constructed with two wires made from different metals or alloys joined at one end, called measuring junction or "hot junction". The measuring junction should be placed at the point of measurement. The other end of the thermocouple is open and connected to the temperaturetransmitter. This point is called reference junction or cold junction.For most applications, the Seebeck effect is sufficient to explain thermocouple behavior as following:How the Thermocouple Works (Seebeck Effect)When there is a temperature difference along a metal wire, a small electric potential, unique to every alloy, will occur. This phenomenon is called Seebeck effect. When two wires of dissimilar metals are joined at one end, and left open at the other, a temperature difference between the two ends will result in a voltage since the potentials generated by the dissimilar materials are different and do not cancel each other out. Now, two important things must be noted. First: the voltage generated by the thermocouple is proportional to the difference between the measuring-junction and the cold junction temperatures. Therefore the temperature at the reference junction must be added to the temperature derived from the thermocouple output, in order to find the temperature measured. This is called cold junction compensation, and is done automatically by the TT302, which has a temperature sensor at the sensor terminals for this purpose. Secondly, if the thermocouple wires are not used, all the way to the terminals of the transmitter (e.g., copper wire is used from sensor-head or marshaling box) will form new junctions with additional Seebeck effects. It will be created and ruin the measurement in most cases, since the cold-junction compensation will be done at the wrong point.NOTEThe relation between the measuring junction temperature and the generated mili-voltage is tabulated in thermocouple calibration tables for standardized thermocouple types, the reference temperature being 0 oC.Standardized thermocouples that are commercially used, whose tables are stored in the memory of the TT302, are the following:. NBS (B, E, J, K, N, R, S & T). DIN (L & U)Resistive Temperature Detectors (RTDs)Resistance Temperature Detectors, most commonly known as RTD’s, are based on the principle that the resistance of metal increases as its temperature increases. Standardized RTDs, whose tables are stored in the memory of the TT302, are the following:. JIS [1604-81] (Pt50 & Pt100). IEC, DIN, JIS [1604-89] (Pt50, Pt100 & Pt500).. GE (Cu10).. DIN (Ni120)For correct measurement of RTD temperature, it is necessary to eliminate the effect of the resistance of the wires connecting the sensor to the measuring circuit. In some industrial applications, these wires may be hundreds of meters long. This is particularly important at locations where the ambient temperature changes constantly.The TT302 permits a 2-wire connection that may cause measuring errors, depending on the length of connection wires and on the temperature to which they are exposed. (See Figure 2.3 -Two-Wire Connection).In a 2-wire connection, the voltage V2 is proportional to the RTD resistance plus the resistance of the wires.V2 = [RTD + 2 x R] x IFigure 2.3 - Two-Wire ConnectionIn order to avoid the resistance effect of the connection wires, it is recommended to use a 3-wire connection (See Figure 2.4 – Three-Wire Connection) or a 4-wire connection (See Figure 2.5 - Four - Wire Connection).In a 3-wire connection, terminal 3 is a high impedance input. Thus, no current flows through that wire and no voltage drop is caused. The voltage V2-V1 is independent of the wire resistances since they will be cancelled, and is directly proportional to the RTD resistance alone.V2-V1 =[RTD + R] x I - R x I = R TD x IFigure 2.4 - Three – Wire ConnectionIn a 4-wire connection, terminals 2 and 3 are high impedance inputs. Thus, no current flows through those wires and no voltage drop is caused. The resistance of the other two wires is not of interest, since there is no measurement registered on them. Hence the voltage V2 is directly proportional to the RTD resistance.(V2 = RTD x I)Figure 2.5 - Four - Wire ConnectionA differential or dual channel connection is similar to the two-wire connection and gives the same problem (See Figure 2.6 - Differential or Dual Connection). The resistance of the wires will be measured and do not cancel each other out in a temperature measurement, since linearization will affect them differently.Figure 2.6 - Differential or Dual ConnectionSIEMENSHighlight of SIMATIC PCS 7 PSLow investment costs.Modular system based on standard components, therefore high degree of flexibility and scalability..Open thanks to the use of standard technologies.Low operation and maintenance costs.Horizontal integration with Totally Integrated Au tomation..Control system specific functionality and components for power plant requirements.

Stream superheating is one of the design features accepted in central electric power stations. Superheating raise overall cycle efficiency. In addition, it reduces a moisture level in the last stages of the steam turbine and thus increases the turbine internal efficiency.Superheaters are commonly classified as either radiant superheaters, convective superheaters, or combined superheaters, depending on how heat id transferred from the gases to steam. These superheaters have different performance characteristics. The feature that the outlet steam temperature can stay essentially constant over a wide range of unit load is the most desirable. When the outlet steam temperature becomes excessive, it may cause failures from overheating parts of the superheater.The convective superheater is located in the furnace exit or in the zone where it can receive thermal energy from the high temperature produces of combustion. The convective superheater is frequently screened from the furnace radiation by a bank of water-filled tubes. These tubes, when adequately spaced, can also intercept the slag particle and reduce slagging problems in superheatrs. Convective superheaters in large steam generator systems are frequently split into two parts: the primary superheater and the secondary superheaater. Saturated steam first enters the primary superheater and receives the initial heating. The primary superheater is located in a zone of relatively low gas temperature. After the partial heating steam moves to the secondary superheater and completes its superheaing process. The main reasons for splitting the superheater are to provide space for the steam reheater and to achieve an effective heat transfer from the gases the steam.The radiant superheater is not as commonly used as the convective superheater. When the radiant superheater is needed, it is usually placed on the furnace wall replacing a section of water-filled tubes. Another arrangement is to have the radiant superheater just behind the screen tubes. The radiant superheater is an integral part of the secondary superheater.Central station boilers provide for steam reheating. The reheater is essentially a convective type and usually located in the space between thee primary and secondary superheaters. After steam partially expands in the tubine, it returns to the boiler for reheating. The temperature of steam leaving the reheater is usually equal to the superheated steam temperature. Since the design and operation of reheater are essentially the same as superheaters, the discussion of superheaters will be equally applicable to reheaters.In superheater thermal design, the steam temperature is first determined. This is generally accomplished in the plant system design, balancing the plant initial cost against the lifttime operating cost. In recent years the optimum steam temperature is approximately 538℃ for all large steam generation systems. In the second step, the amount of superheater surface required is approximated.After the amount of superheater surface id determined, the next consideration is to select the tube length, tube diameter, and the number of tubes. Evidently, the selection is an iterative process, generating a trial solution and checking to see whether all constraints are met. From several acceptable solutions, the optimum is found. The optimum superheater should have enough heat transfer surface necessary to give the design steam temperature. The tube parameters(length and diameter) are such that the steam pressure drop and tube metal temperature willnot exceed the design values. The tube metal temperature is an important parameter and has a strong influence on the tube material selection. In addition, the optimum superheater should have its tubes so spaced that minimum ash and slag deposits will result.Modern superheaters have many tube passes, and the tubes are arranged in-line rather than staggered. The tubes are usually cylindrical and have 5 or 6.3cm outside diameter. There is no extended surface(i.e.fins)attached to the tubes. The material selection depends on the steam temperature and pressure. Carbon steel has an allowable temperature up to 430℃ and is frequently used for loe-temperature superheaters. Chrome-moly, stainless steel, or same similar heat resistant alloy can withstand the temperature up to 650℃. Therefore they are selected for the Superheater in a high-temperature zone.Temperature regulation and control are importation for both superheaters and reheaters. Steam temperature adjustments are frequently made at the time of the commissioning of a boiler. The principal methods are an addition or regulating the hot gas temperature and mass flow rate. These are generally accomplished by changing the excess air or the effectiveness of the evaporation section.During a boiler operation, there are many factors affecting the temperature of steam leaving the superheater and reheater. These include a boiler load, excess air, feedwater temperature, and cleanliness of heating surfaces. Control of steam temperature during operation must be done without changing the arrangement of equipment. The most effective approaches are gas bypass, burner control, attemperation, gas recirculation, excess air, divided furnace.A gas bypass is to control the gas flow rate to superheater. The main disadvantages of this approach are the operating difficulties experienced by the movable dampers located in the high-temperature zone and the slow response to load change.Burner control is used to control the flame location and combustion rate. Tilting burners can direct the flame toward or away from the superheater. These will result in a change of heat absorption in the furnace and change of gas temperature in the superheater. As the boiler load is reduced, burners are removed one by one from service. This will change the combustion rate and, thus, change the gas flow rate to the superheater.Attemperation is one of approaches frequently used. The attemperator is usually located at the point between the primary and secondary superheaters.There are two basic types of attemperator. The first is the tubular type in which some of superheated steam is passed through the tubes of a heat exchanger and has heat transferred to the boiler water(either boiler feedwater or water in the boiler drum).Subsequent to attemperation, the divided streams from the primary superheater will combine and enter the secondary superheater.The second type of attemperator involves a spray of feedwater into the atream ofsuperheated steam. The feedwater evaporates and reduces the steam temperature. Controlling the amount of feedwater will result in control of the ateam temperature. Care must be exercised to ensure that the spray water has sufficient purity. Thespray water should mix well with the superheated steam so that there are no water droplets in the inlet of the secondary superjeater.Gas recirculation is used to control the steam temperature by changing the heat absorption rates both in the furnace and in the superheater. When the ateam temperature needs to be raised, some of the furnace. Therefore, the furnace temperature will become lower, resulting in a lower heat absorption in the furnace and thereby a higher flue gas temperature in the furnace exit. This high gas temperature, combined with an increase in the gas floe rate, will increase the heat transfer rate in the superheater and thus increase the steam outlet temperature.Temperature control can be affected bu using different amounts of excess air. the more the excess air, the higher the steam outlet temperature would be. The reasons for this are similar to those for the gas recirculation method. It must be pointed out, however, that too much excess air will result in a reduction of boiler combustion efficiency. A divided-furnace boiler is usually arranged with a generation of saturated steam in one section and a superheating of steam in another section. The temperature of the superheated steam is regulated by controlling the firing rates in the two furnaces. This method is not economical and is seldom applied in a central electric power station.。
