Thermal power plants in China most bituminous coal burning, but with the power consumption is more and more big, the demand for coal more and more. But because of bituminous coal prices higher can cause power cost is higher, so many of the burning coal power plant boiler has hope will switch to cheaper by the bituminous coal anthracite. Transformation of the coal happen before and after the great change, change so that boiler when it will have some problems. In this paper, the characteristics and the economical efficiency of coal power plant every link of coal quality paper characteristics of the power station efficient influence. Including volatile matter, moisture, ash, heat, lying in detail. For bituminous coal boiler burning righteousness horse change when jingxi anthracite respectively, the two kinds of the thermal coal auxiliary calculation. Including boiler air leakage coefficient and the balance of the air quantity determine calculation, fuel combustion calculation, and air flue gas enthalpy of calculation, boiler heat efficiency enthalpy and fuel consumption estimate, hearth checking thermodynamic calculation. And the results calculated a comparative analysis. In addition, the chamber structure schematic drawing size, write platen superheater flue gas into circulat
