【Abstract】 Since the traditional calculation of carbon loss goes against the finding of on line energy loss,a new analytic evaluation model based on coal quality and operational characteristics is built up through deduction and experimental analytical research.Thus the quantitative search of factors causing carbon loss is realized.The accuracy of this model is validated through testing coal quality parameter,combustible basis volatile flux V daf ,operational characteristic parameter and the excess air coefficient of furnace outlet α 1,which provides basis for energy conservation and consumption drop.更多还原
