Abstract
PURPOSE: To accomplish low-NOx combustion of fuel, by disposing a plurality of burner sets horizontally, each of said burner sets consisting of a main burner and an auxiliary burner, and disposing a pluraity of sets of an air port and an after-burner on the downstream side of said burner sets in respect of the flow of exhaust gas.
CONSTITUTION: The burner set 5 is constituted by a main burner 2 for combusting fuel at an air-fuel ratio higher than 1 and an auxiliary burner 3 disposed downstreams of the main burner in respect of the exhaust gas for combusting fuel at an air-fuel ratio lower than that of the main burner. A burner group is constituted by arranging a plurality of such burner sets 5 in a plurality of stages, for instance, in a zigzagged manner in the front wall and the rear wall of a furnace 1. In such an arrangement, a plurality of sets 4 of an after-burner and an air port capable of supplying the shortage of combusting air required for complete combustion of fuel are disposed on the downstream side of the burner sets 5 in respect of the exhaust gas, whereby it is enabled to accomplish low-NOx combustion of fuel.
