Analysis of New Pulverized Coal Combustion Technology of Super Critical Pressure Boiler

FAN Quangui(North China Electric Power University, Baoding 071003,China)  
This article analyzes the new type pulverized coal combustion technology adopted in the indigenous supercritical pressure boiler.The main features are:to adopt different comprehensive technological conceptions to realize low oxygen combustion in the imitial stage ignition,to adopt multistage air distribution and NO_x reduction technology to realize low pollution emission,to strengthen hot gas back flow in the vicinity of exhaust nozzle of burners to realize quick ignition and steady combustion at low load without oilaid fiving,to adopt low power burners and equilibrium flame temperature to decrease the thermal load of watercooled wall,to adopt whirl burnersopposed arrangement or impellerless burnersback bitangential radiationcontraflow complement to reduce thermal deflection,and to appropriately increase furnace volume and arrange burnout air to further raise furnace deNO_x effect and improve combustion efficiency etc.
