  • Combustion Of Fluid Fuel (AREA)

Abstract

PURPOSE: To prevent mutual interference, and to decrease NOx by arranging a nozzle ejecting an inactive fluid between mutual fines fuel burners when two or more of the burners formed by three compartments are disposed adjacently.
CONSTITUTION: The fines fuel burner is 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 fuel, the second is two fuel blowing-in port 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 molded by an air passage 55 and a nozzle 54. When two or more of the burners are arranged adjacently, the inactive fluid nozzles 56 are disposed among the burners, and an inert gas such as combustion exhaust gas is blown into a furnace. Accordingly, mutual interference among the burners is obstructed, the change of a mixture of air and the fines fuel is prevented and the increase of NOx is obviated.
