Abstract:Superheated steam temperature is a variety of important industrial boiler equipment parameters, in the production process, the entire path of soft drink is the highest temperature of superheated steam temperature, superheater temperature normal working hours, there are generally closer to the material to allow the maximum temperature, if overheating steam temperature too high, easy to damage superheater Leabharlann Baidund steam turbine will cause excessive internal seriously affected the production of thermal expansion of the safety of operation; superheated steam temperature is low, it will reduce the efficiency of equipment, while the adoption of the final class of steam turbine steam humidity increased, the wear and tear caused by the leaves. Therefore, we must control the export steam superheater temperature. Overheated steam boiler control is tantamount to the task, that is, in order to maintain the export steam superheater temperature in the permit, and to protect the superheater tube wall temperature does not exceed allowable operating temperature.
锅炉是化工、冶炼、发电等作为公用民用部门必不可少的主要动力设备，其产品是蒸汽，即将一次能源（煤炭、石油、提燃气等）转换为二次能源（蒸汽）。
工业锅炉是工业生产的重要设备，往往直接影响生产的正常进行和产品的质量、产量和成本。工业锅炉又是能耗极大的设备，在整个工业生产的能源消耗中占相当大的比重。而燃煤锅炉又是一种广泛实用的工业锅炉，广泛地使用于国民经济各个领域。由于技术落后、设备陈旧、操作水平低下，目前我国工业燃煤锅炉普遍存在着热效率低、能耗高的问题。据不完全统计，我国共有各类锅炉近四十万台，每年的耗煤量达三亿多吨，占我国原煤产量的三分之一。由于煤质变化大，设备陈旧，不仅工人劳动条件差，劳动强度大，而且锅炉热效应低。由此可见，提高锅炉的效率，具有十分重要的意义。然而我国近些年来的实践表明，除设备本身经过合理改进或采用先进的节能设备外，另一条节能的途径就是通过对锅炉的自动控制。此外，要想实现锅炉安全运行，保证向用户提供高质量的蒸汽，减轻工人的劳动强度，减少环境污染等目的，采用自动控制也是必须的。

随着科学技术的飞速发展，带动社会生产的发展，人类对能源的需求不断增加，世界上发达国家为了解决能源紧张而带给各行业的冲击，都努力在开发能源的同时，致力于节能新方案的研究。
摘 要：过热温度是各种工业锅炉设备的重要参数。如果过热蒸汽温度过高，则过热器容易损坏，也会使汽轮机内部引起过度的热膨胀严重影响生产运行的安全；过热蒸汽温度偏低，则设备的效率将会降低，同时使通过汽轮机最后几级的蒸汽湿度增加，引起叶片的磨损。因此，必须控制过热器出口蒸汽温度。锅炉过热蒸汽温度的控制任务，就是为了维持过热器出口蒸汽温度在允许的范围内，并保护过热器管壁温度不超过允许的工作温度。
