Study on Computational Methods for the Refractory Belt Area of Coal Fired Boilers

Abstract:

The worse coal quality cause low center flame temperature in furnace, low combustion stability, high carbon content in fly ash and slag. The refractory belt installed in primary combustion zone can reduce the heat absorption capacity of water wall and improve the average temperature to steady ignition and high efficient combustion. For conforming the area of refractory belt better, the equation was founded by thermal computational methods and analyzing the different influence to the area of refractory belt.
