摘　　要：某电厂1000MW二次再热燃煤机组在投产运行后,干排渣系统漏风量大于设计值,掺烧部分印尼煤和低热值烟煤,导致空预器排烟温度偏高。本文分析了原因,提出可行的技术方案,并具有良好的经济性。After a 1000 MW secondary reheat coal-fired unit in a power plant was put into operation,the air leakage rate of the dry slag removal system was greater than the design value,and some Indonesian coal and low calorific value bituminous coal were blended,resulting in higher exhaust gas temperature of the air preheater.This paper analyzes the reasons and puts forward a feasible technical scheme,which has good economy.
