摘要

介绍了在华能太仓发电有限责任公司超临界机组4号锅炉调试中采用稳压和不熄火降压方式蒸汽吹洗的情况。吹洗结果表明

4号锅炉无论采用稳压或不熄火降压方式吹洗

均能保证要求的吹管系数及吹洗质量。不熄火降压方式吹洗的效果优于稳压法

且省时、省燃料、省除盐水、操作简化。

Abstract

The situation of steam blowing by using pressure-stabilizing method and pressure-reducing method under condition without putting out the fire in debugging process of boiler no.4 for supercritical unit in Huaneng Taicang Power Generation Co Ltd has been presented.Practice in blowing shows that the required pipe-blowing coefficient and blowing quality can be ensured no matter what method is used for steam blowing

however

the effectiveness of pressure-reducing method under condition without putting out the fire is superior than that of pressure-stabilizing method

saving time

fuel

and desalting water

and being simple in operation.
