摘要

对国华惠州热电厂330MW机组WGZ1100/17.45-3型锅炉排烟温度偏高的原因进行了分析

认为其主要因炉膛本体及制粉系统漏风、磨煤机一次风掺冷风量过多、炉内结焦和受热面积灰等所致。对此

提出了增加空气预热器面积

利用一次风和排烟加热凝结水等措施

实施后排烟温度明显下降。

Abstract

Serious high exhaust gas temperature occurred on WGZ1100/17.45-3 type boiler of 330 MW unit in Guohua Huizhou Thermal Power Plant.After analysis

air leakage in furnace and the corresponding system

too much cold air entering the coal pulverizer

slagging and fouling on heating surface were considered as the main reasons.Thus

several countermeasures were carried out

such as increasing the heating surface area of preheater

heating the condensate water by primary air and exhaust gas etc.Through these improvements

the exhaust gas temperature decreased obviously.
