  • Combustion Of Fluid Fuel (AREA)

Abstract

PURPOSE: To decrease NOx by mutually arranging the same kind of compartments of each fines fuel burner at symmetric positions when two or more of the burners formed by three compartments are disposed adjacently.
CONSTITUTION: The fines fuel burners are shaped by the three compartments. The first is that the amount of air is less than the theoretical amount of combustion air for a volatile matter in the fuel, the second is two fuel blowing-in compartments in which the amount of air is approximately equal to the theoretical amount of combustion air, and the first and the second are each formed by fuel nozzles 45, 48, fuel mixture passages 44, 47, air passages 52, 53 and secondary air nozzles 50, 51. The third auxiliary air compartment is shaped by an air passage 55 and a anozzle 54. When two or more of the burners are arranged adjacently, the same kind of the compartments are mutually disposed at the symmetric positions. Accordingly, even when mutual interference happens, the same kind of a mixture or air is formed, the change of the rate of the mixture of air and the fines fuel is prevented, the fuel is burnt under the optimum condition and NOx is decreased.
