This paper analyzed the operating conditions of the W-type flame boilers of 300 MW in Heze Power Plant,in accordance with its designed characteristics.With the burning of non-designed coal,there are many problems in boiler equipments,such as overload running of pulverizing system,over high flow of primary air and high the mass fraction of unburned carbon in fly ash etc.Based on this,this paper proposed adjusting of the combustion,enhancing regulation of coal,increasing safeguard belt zone,improving pulverize power.The application experiences show that the combustion stability and efficiency of boiler has been improved greatly.
