摘要

谏壁发电厂2×330 MW机组锅炉燃用神东煤发生严重结渣

对此进行了试验分析

认为结渣是由于炉内燃烧切圆偏斜、燃烧器区域热负荷偏高、一次风周界风挡板开度太小、吹灰不合理、燃尽风挡板开度小等原因造成。对此

采用高、低灰熔点煤混烧并从运行方面采取了一系列针对性调整措施

取得了显著的效果。对锅炉吹灰器布置设计提出了建议。

Abstract

Serious slagging had occurred in boilers of two 330 MW units in Jianbi Power Plant burning Shenfu-dongsheng coal.For this

test and analysis have been carried out

the mixed burning method of coals with high and low ash fusing point being adopted

and a series of adjusting measures with clear aim being taken from the aspect of operation.obtaining remarkable result.In addition

recomondations for soot-blowers' layout design of the boilers have also been put forward.
