摘要： PROBLEM TO BE SOLVED: To reduce the NOx in a combustion exhaust gas by improving a combustion device wherein the secondary air is supplied to the primary combustion flame for the secondary combustion, after the primary combustion of the fuel and the primary air of less than theoretical amount of air.
SOLUTION: In this combustion device comprising a fuel supply nozzle 11 for supplying the fuel, a primary air supply nozzle 12 for supplying the primary air of less than the theoretical amount of air to the fuel supplied from the fuel supply nozzle, a primary combustion part 13 for burning the fuel and the primary air, and a secondary air supply nozzle 14 for supplying the secondary air at an outer peripheral side of the primary combustion part, one or more secondary air supply nozzles are mounted within a range of 160° to a center of the primary combustion part, and the secondary air supply nozzles are inclined outward with respect to the primary combustion part.
