Abstract：In order to alleviate the shortage of designed coal and decrease cost in coal-fired power plant,the key parameters of blending coal were analyzed. Based on the whole production procedure of coal-fired power plant,a multi-aspect model for blending coal burning was designed. The application of the model in Kangping coal-fired power plant was investigated. The model was composed of four function parts which were coal purchasing management,coal yard management,coal blending management and blending combustion management. The model could determine the cost-effective blending coal solution according to the coal properties,slag and ash characteristics,pollutant e-missions,market requirement,coal storage state in yard,boiler running conditions and so on. The model helped Kangping coal-fired power plant consume 3. 5 x106 tons local raw coal,saved transportation costs more than RMB 6x107 ,saved raw coal 6. 1x105 tons,reduced CO2 emissions 1. 5x104 tons every year.
