摘  要:某电厂供热期间长期处于低负荷运行,锅炉运行参数较差,该厂未设计主、再热烟气挡板,常规调整方法无法平衡主、再热汽温低与锅炉悬吊管壁温高之间的矛盾。经过分析与实验,提出借用高位燃尽风风门偏差的方法,进行锅炉蒸汽参数调整,取得良好效果。During the heating period of a power plant,the boiler is in low load operation for a long time,and the operation parameters of the boiler are poor.The main and reheat flue gas baffles are not designed in the plant,so the conventional adjustment method cannot balance the contradiction between the low main and reheat steam temperature and the high wall temperature of the boiler suspension pipe.Based on the analysis and experiment,the method of using the deviation of high burnout air valve to adjust the steam parameters of the boiler has been put forward,and good results have been achieved.

关 键 词:主再热汽温 锅炉壁温 高位燃尽风
