摘　　要：某厂掺烧焦炉煤气的660 MW等级超临界锅炉,原设计未带有炉水循环泵,我们通过对启动系统增加疏水再循环管和对热一次风母管上的暖风器位置改进的方法,克服了化学制水能力的限制,节约了大量除盐水和燃料,对热源实现了再循环利用,缩短了机组启动时间,实现了节能减排的目的。The original design of 660 MW supercritical boiler of co-combustion coke oven gas in one power plant did not contain the boiler water circulating pump. Through adding the hydrophobic recirculating pipe for the start system and improving the air heater location, the capability of limitation on chemical water production was conquered. The fuel and desahed water were largely saved. It realized the recycling of thermal source, which decrease the unit start-up time and realize the objective of energy saving and emission reduction.
