摘　　要：结合我国第一台使用炉水循环泵启动系统的3033t／h超超临界直流锅炉的特点,通过分析计算,比较了目前主要的两种锅炉吹管工艺的优缺点,并指出超超临界锅炉不宜采用稳压吹管,而应采用熄火降压吹管,给出了吹管压力和工艺流程。Based on the analysis of the first 3033t/h ultra-supercritical once-through boiler with a recycle pump, advantages and disadvantages of two main kind of steam purging techniques currently employed are compared through calculation. It is concluded that intermittent pressure cycle purge instead of stable-pressure continuous purge is suitable for ultra-supercritical pressure boiler. Starting pressure and procedure of intermittent pressure cycle purge is also given.
