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。
由于火力髮電的燃料成本約佔髮電成本的70％以上，且近年來煤炭價格不斷上漲，火電企業利潤大幅下降，齣現行業性虧損。為改善火電企業經營狀況，許多火電廠正在摻燒非設計的、價格相對較低的煤種，介紹瞭國內某電廠摻燒褐煤和印尼煤的概況和具體實施方案，研究瞭不同摻燒煤種方案對鍋爐效率的影響，併對產生的經濟效益進行分析，為同類型電廠提供有益參攷。

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.
