摘　　要：由于火力发电的燃料成本约占发电成本的70%以上,且近年来煤炭价格不断上涨,火电企业利润大幅下降,出现行业性亏损。为改善火电企业经营状况,许多火电厂正在掺烧非设计的、价格相对较低的煤种,介绍了国内某电厂掺烧褐煤和印尼煤的概况和具体实施方案,研究了不同掺烧煤种方案对锅炉效率的影响,并对产生的经济效益进行分析,为同类型电厂提供有益参考。The fuel cost accounts for over 70% the total generating cost. With the continuous roaring of the coal price, the profit of the thermal power enterprises has decreased substantially and as a result the whole thermal power industry even operates in loss. In order to improve this operation situation, some thermal power plants try to add the non-designed low price coal to the fuel. This paper introduces the general situation and actual execution schemes of blending lignitous coal and Indonesia coal in a power plant, studies the influence of different blending schemes on the boiler＇s efficiency, and makes an analysis on their economic benefits, which can be used as a reference for other similar power plants.
