1 000 MW机组锅炉大风箱烧损原因分析与控制策略

Causes Analysis and Contrd Strategies of Burning Loss of Big Bellows in 1000 MW Power Plant Boiler

对哈尔滨锅炉厂有限责任公司HG-3159/29.3-YM6型锅炉低负荷时大风箱烧损的现象进行了分析,给出了导致大风箱烧损的4个原因,并对1个不确定因素进行了实验。实验证明该分析准确无误。针对如何避免大风箱烧损的问题给出了切实可行的解决办法,对该锅炉安全运行有重要指导意义,并对同型号和同风箱布置形式的锅炉机组试验具有借鉴意义。

This paper described the burning loss of big bellows of HG-3159/29.3-YM6 boiler under low load in Harbin Boiler Factory Co.,Ltd.,analyzed the four causes of the fault,and analyzed one uncertain factor.The result of the test can prove that the analysis is sure.It proposed practical methods to solve the problem of the burning loss of the big bellow,which has important guiding significance for the safe operation of the boiler,and it is of reference significance for the boiler unit test of the same model and the same bellow layout.
