石煤与烟煤的混燃特性研究

Characteristic research on combined combustion of stone coal and bituminous coal

利用1 MW循环流化床试验台进行了石煤和烟煤的混燃试验,对燃烧过程中炉膛温度、燃烧效率、成灰特性的数据进行了分析,结果表明石煤与烟煤混燃稳定,燃烧效率较高,灰渣的粒度特性有利于灰渣的综合应用,可为石煤的综合利用技术提供依据。

Stone coal and bituminous coal combined combustion experiment was proceeded on 1 MW circulate fluidized bed. Data on furnace temperature,combustion efficiency and ash formation was analyzed in combustion process. The conclusion was that stone coal and bituminous combined combustion was stable and its combustion efficiency was high,size characteristic of ash slag was beneficial to comprehensive utilization. Necessary referrence for further promotion and application of stone coal was furnished.
