关键词：燃气轮机；压气机；在线水洗；离线水洗；经济效益abstract: this paper briefly introduces the composition and working principle of 9fa type gas turbine, the operation of the compressor washing work is elaborated, discusses the encountered in the process of water problems and solutions, and puts forward some ideas and solutions to improve the evaluation, and the corresponding benefit.keywords: gas turbine; compressor; online washing off-line washing; economic benefit;中图分类号：u263.11文献标识码：a 文章编号：为适应国家电力供应发展的多样化，以各种新能源、清洁能源发电的电厂建设正在逐步丰富和完善我国以燃煤为主力发电的格局。
在工业发达、用电量高的大中型城市，电网的负荷需求在白天和夜晚的变化很大，这就需要多样化的调峰手段来保证电网的安全稳定运行。
以天然气为燃料的燃气轮机电厂，具有启停方便、运行灵活等优点，成为了电网调峰的主要手段之一。
9fa型燃气轮机为美国通用电气公司(ge)生产，一般采用燃气—蒸汽联合循环布置，以提高发电效率，在国内具备一定的装机规模。
1 系统介绍9fa型燃气轮机主要由一台18级的轴流式压气机、一个由18个低nox燃烧器组成的燃烧系统、一台3级透平和燃机辅助系统组成。

电厂闭式冷却水系统窜入空气原因分析
第40卷第2期2019年4月电力与能源267D()I：10.11973/dlyny201902035电厂闭式冷却水系统窜入空气原因分析崔超，朱挺进，李大超(华能营口热电有限责任公司，辽宁营口115000)摘要：闭式冷却水系统是电厂的重要系统，其作用是向冷却水质要求高的设备提供冷却水。
闭式水系统的故障直接影响着主机设备、辅机设备的安全稳定运行。
以华能营口热电厂1号机组闭式水系统窜入空气为出发点，找岀了空压机冷却器内部管路破裂是引起闭式水窜入空气的主要原因。
关键词：闭式冷却水；窜入空气；氢气冷却器；空压机冷却器作者简介：崔超(1990-).硕士，工程师•从事电厂集控运行工作。

康明斯公司推荐在大多数气候条件下使用50％乙 烯乙二醇或丙烯乙二醇基的防冻液与50％纯净水 的混合液作发动机的冷却液。对使用湿缸套的C系 列以上的发动机还需要添加规定浓度的防腐蚀剂 DCA4。某些新型防冻液可以不需要DCA4，如加 德士公司的Extended Life Coolant.

Desert climates in the northern Sonoran Desert are typified by warm days but sometimes experience nighttime temperatures that are below freezing in the winter.Young saguaros that survive are found sheltered beneath more frost-tolerant desert shrubs.The cover of these shrubs acts as a thermal blanket,capturing heat radiated from the ground and keeping the microclimate of the small saguaro warm at night.As thecactus grows,it eventually rises above the cover of the protective shrub.The radiation of heat from the stalk of the large mature cactus prevents freezing.This strategy works up to a point.The range of the saguaro is restricted to areas that do not experience more than about 12to24continuous hours of air temperatures below0℃.It appears that after24hours of freezing air temperatures,not enough heat reserve is left in the saguaro to keep the tissue from freezing.译文植物适应寒冷环境①有许多有趣的适应性可以让植物在凉爽的环境中生存。

9FA燃机水洗系统解析
9FA燃机水洗系统解析摘要：燃气轮机在运行一段时期以后，为了恢复压气机的性能，要求定期对其通流部件进行清洁。
本文旨在通过对燃机压气机水洗系统的分析、解读，全面掌握水洗过程控制，完成控制系统的国产化自主改造，保障机组运行的可靠性和安全性。
关键词：燃机压气机、水洗、PLC0 引言某电厂现有GE公司S109FA燃气-蒸汽联合循环发电机组，机组投运已十余年，控制系统硬件设备已不能满足机组长期运行要求，通过燃机控制系统（TCS）国产化自主改造，全面更新控制系统硬件设备及软件系统。
分析、解读燃机压气机水洗系统，全面掌握水洗过程控制，完成控制系统的国产化自主改造。
为机组水洗系统的试验及正常投运提供技术支持。
1 概述燃气轮机运行一段时期以后为了恢复它的性能，要求定期对通流部件进行清洁。
一些油性的污染物，如碳氢化合物烟气，必须用含有洗涤剂的水溶液将它们清洗掉。
对于烧天然气的燃气轮机机组，配备有压气机水洗装置。
通常可采用两种水洗方法，在线水洗和离线水洗。
机组在接近基本负荷、IGV全开时，将水喷向压气机进行清洗的方法称在线水洗。
当机组以冷拖方式运行，向压气机喷射清洗液进行清洗，则是离线水洗。
在线水洗的优点是可以在不停机的状态下完成，但它的效果没有离线水洗好，因此在线水洗不能替代离线水洗。
水洗模块装置具有“自动在线清洗”、“轮间温度报警”和“水箱温度控制”三个控制电路。
接线盒控制面板用于支持与最多4台燃气轮机控制系统进行通信。
逻辑功能由位于电气控制中心内的可编程控制器（PLC）完成。
模块的操作由中央控制室进行控制。
2 压气机在线水洗压气机在线水洗需具备的条件：1、机组在运行状态；2、IGV开度大于70°；3、压气机进口气温和水洗的水温大于10℃；4、IBH在关闭状态，且未采取强制关闭措施。
在线水洗操作步骤：检查水洗气动门前三通阀在中间位置、水洗水箱液位大于800mm等允许条件满足后，操作员控制机组负荷略低于基本负荷，使燃气轮机从温度控制过渡到转速控制，在“On Line Water Wash”画面上，点击“ON”，在线水洗正式开始，水洗泵启动，并持续15min，在30min时结束在线水洗程序。

It was specially developed for extremely large CPU DIEs and fully covers processors such as the AMD Threadripper but also the AMD Ryzen CPUs. The Eisbaer Pro has also been designed for the Intel Socket 3647 to ensure the best possible cooling performance of the entire CPU. The Eisbaer Pro is a true multi-talent. Expandable, fully compatible with DIY water cooling components and it is the optimal solution for the most powerful processors on the market.Large cooling surfaceThe cold plate bottom covers the entire surface of the respective processors. The area of the cooling fins exceeds all known processor cores with an area of around 55 x 42mm. This ensures that all hotspots of a CPU are directly covered and thus optimally cooled. With the included AM4 bracket, cooling an AMD Ryzen processor is also child's play. The cooling fins are 0.4mm thick and also have an optimal distance of 0.4mm between them. In total there are 58 cooling fins on the bottom of the cooler. The bottom of the cooler is only 3mm thick, which allows the heat to reach the water and be dissipated as quickly as possible.PumpThe Eisbaer Pro ES (Solo) cooler uses the very compact and small DC-LT 2 pump. It offers enough power to integrate other components such as a GPU water cooler or radiator into the water circuit.Usable fittingsConnections that are too large mean that the fill port can no longer be used. We recommend the following:- up to and including 13/10 without restriction- 16/10 only in angled version- Connections larger than 16/10 should not be usedDrawing。

GENERALThe cooling water system is designed to accommodate the heat dissipation requirements of the lubricating oil system, atomizing air pre-cooler, turbine supports and flame detector mounts, generator gas coolers, and the LCI cooler (if required). The components of the cooling water system are located on the accessory module, the liquid fuel/atomizing air module, the gas turbine base, the generator base, and the LCI base (if required).(冷却水系统的设计，以满足滑油系统，雾化空气预冷器，透平支撑腿，火焰探测器，发电机和LCI的冷却（如果需要）。

）II. FUNCTIONAL DESCRIPTION（功能描述）A. Accessory Module（附件模块）1. Lubricating Oil System（润滑油系统）The lubricating oil cooling system components consist of two heat exchangers (LOHX1 & LOHX2), a temperature regulating valve(VA32–1) and butterfly valves. Two heat exchangers are provided so that one is in operation cooling the lubricating oil while the other one is being maintained. Only one of the heat exchangers is to be in service during operation. The exchanger not in service must have the coolant return isolation butterfly valve closed. Both supply and return isolation valves should not be closed for an extended period of time on the inactive heatexchanger as this will then be an enclosed volume. In an enclosed volume, any thermal fluid expansion could result in an external leak. （润滑油冷却系统设备由两个热交换器（LOHX1&LOHX2）,一个温度调节阀（VA32-1）和蝶阀组成。
两个热交换器互为备用。
只有一个冷油器工作，备用冷油器的蝶阀必须关闭。
在备用冷油器上的进出口隔离阀都不应该长时间关闭，因为这是一个封闭的空间在，任何热的流体膨胀都可能造成外部泄漏。
）To change from one heat exchanger to the other while the gas turbine is operating the following steps are to be followed: 1) Open the lubricating oil fill valve and allow the heat exchanger to fill with oil until flow is observed in the sight glass. 2) Open the closed coolant isolation valve on the exchanger currently not in service. Coolant is now being circulated through both heat exchangers. 3)Operate the oil transfer valve to direct the total oil flow to the heat exchanger that will now be in service. 4) Close the coolant return isolation valve on the exchanger with no oil flow.（燃机在运行期间切换冷油器时要遵循以下步骤：1.打开润滑油充油阀给备用冷油器冲油直到观察口有连续的油流出；2.打开备用冷油器的冷却水隔离阀；3.操作切换阀至备用冷油器，使全部的油流通过；4.关闭先前运行的冷油器冷却水隔离阀）The temperature-regulating valve (VA32–1) is provided to control the lubricating oil header temperature. The three-way valve bypasses coolant around the heat exchanger allowing the correct coolant flow to maintainthe oil within the temperature control range. An Electro-pneumatic Temperature Controller (90LT–1) regulates the valve.If the oil temperature outside of the heat exchanger exceeds the setpoint temperature, then the signal from 90LT–1 will open the control valve further in the B–L position, allowing more coolant to flow through the heat exchanger and thus reducing the oil temperature. If the oil temperature out of the heat exchanger is less than the setpoint, then the signal out of 90LT–1 will open the VA32–1 valve further in the B–R position, reducing the flow of coolant to the heat exchanger and thus reducing the oil temperature. On start up of the gas turbine, the valve is usually closed to the heat exchanger and will open as the oil temperature reaches the control temperature range. The Cooling Water Control Valve arrangement also includes a Pneumatic Pressure Regulator (VPR64–2).An override crank is also provided on the valve to allow manual control. （通过温度调节阀（VA32-1）来控制滑油出口温度。
三通道阀旁路控制通过冷油器中冷却水的流量，保证滑油温度在正常范围。
电-气温度控制器（90LT-1）调节此阀门。
如果滑油温度超过设定温度，从90LT-1来的信号将进一步打开控制阀B-L侧，允许更多的冷却水通过冷油器以此降低滑油温度。
