摘要(Abstract)：
近年来,由于煤价的上涨,迫使许多大型燃煤发电厂燃用进口劣质煤。将印尼煤和中煤混配进行了燃烧试验,对锅炉的运行经济性以及检修、停炉时间、厂用电等因素造成的费用变化进行了计算分析,结果显示燃烧劣质煤带来的检修、厂用电等费用的增加明显小于混配煤带来的效益,即混配燃烧具有良好的经济性。
In recent years,many domestic large coal-fired power plants have to use imported inferior coals due to rise in coal prices.The paper brings forward testes for mixed-firing Indonesian with chinese coals to calculate cost change due to changes of such factors as economical efficiency of the operation of boilers for which Indonesian coal and domestic coal are blended,maintenance,duration of boiler shutdown and auxiliary power.The increased cost of maintenance and auxiliary power due to inferior coals is significantly less than the benefit from the blended coals,and hence it is concluded that the mixed-firing can acquire favorable economical efficiency.
