| 摘 要： | 潮州电厂3号、4号1 000 Mw 超超临界燃煤机组在运行过程中多次出现主蒸汽温度、再热蒸汽温度大幅度波动且偏离设定值的问题.为此,对机组主蒸汽温度、再热汽蒸温度波动较大的原因进行分析并提出详细的优化方案.分析结果认为中间点温度波动大、给水调节策略存在问题是主蒸汽温度波动大的主要原因;减温水调节阀投入自动时超调量大,烟...

| Abstract: | The main and reheat steam temperature drastically fluctuates and deviates from setting value on many occasions during the operation of the 3rd and 4th 1 000 MW ultra supercritical coal-fired generating units in Chaozhou Power Plant.Therefor,causes for drastic fluctuations of main and reheat steam temperature are analyzed and detailed optimization proposals are brought forward.The analysis result indicates that the fierce temperature fluctuations at the intermediate points and problems in strategy for feed w... |
