As we all know , the design coal select specific boiler , boiler fuel coal . In practice, however, due to the tension of coal resources , coal prices , leading to more and more difficult to have been burning in the actual operation of the plant design coal , coupled with cost - saving considerations , blended coal combustion has become Most plant selection . This article describes an overview of Shanxi Datang International Yungang Thermal Power Plant 300MW boiler . Blended coal combustion pulverizing system , boiler operating performance , the impact on the economy . By thermodynamic calculation of the blended coal combustion boiler furnace , superheater , reheater , economizer, air preheater the condensate residue tubes and boiler tubes , the impact of the additional boiler heating surface . The comparative analysis of the boiler results in the original design checking coal and mixed coal thermal coal in three load (95% BMCR, 100% BMCR, 105% BMCR) to provide for the safety and economy of the boiler operation reference.
