In order to solve the problem that the operating parameters of the boiler cannot be well grasped when different types of coal are co-burned,takes a 660 MW"W"flame boiler as the research object,and uses the detection method of 100％heat consumption according to the current burning Yima bituminous coal(black coal)as the research object.The numerical simulation method was used to analyze the effective utilization heat,flue gas velocity and temperature,and NOx,SOx,CO yield of the two coals under different ratios.
