目的:掺煤混乱,煤种随意搭配,不但不能防止锅炉结焦,降低发电煤耗率,反而影响锅炉安全经济运行.通过测算和试验得出最佳配煤方式,能有效防锅炉结焦,提高锅炉燃烧效率,相对降低锅炉发电原煤耗率.同时为采购部门选择煤种提供依据,引导燃料分场合理配煤输煤. The purpose of this paper is to confuse coal and mix coal freely, which not only can not prevent the boiler from coking and reduce the coal consumption rate of power generation, but also affects the safe and economic operation of the boiler.According to the calculation and experiment, the optimal coal blending method can effectively prevent the boiler coking and improve the boiler combustion Efficiency, relative reduction of raw coal consumption rate of boiler power generation.At the same time for the procurement department to provide the basis for selection of coal, and guide the fuel sub-ration with coal rationing.
