在许多电厂中,电站锅炉都不同程度地存在着蒸汽温度偏离设计值的问题.针对某电厂3#锅炉主蒸汽温度、再热蒸汽温度同时偏低的问题,编制适用于此锅炉的热力计算程序.在改变几种运行工况进行热力计算、分析计算结果后,得出了不同参数的改变对炉膛出口烟温、过热蒸汽、再热蒸汽、排烟温度的影响规律,为改善锅炉汽温特性、解决汽温偏低的问题提供依据.
In many power plants, power plant boilers have different degrees of deviation from the design value of the steam temperature.For a 3 # boiler main steam temperature, reheat steam temperature at the same time the problem of low, the preparation of the thermal calculation program for this boiler After changing several operating conditions for thermal calculation and analyzing the calculation results, the influence of different parameters on the flue gas temperature, superheated steam, reheat steam and exhaust gas temperature at the outlet of the furnace was obtained. In order to improve the steam temperature characteristics , To solve the problem of low temperature to provide the basis.
