Abstract

PURPOSE:To miniaturize a burner device while economically decreasing NOx, by a mechanism wherein exhaust gas is recirculated by forming a flame central portion in negative pressure. CONSTITUTION:Secondary air 13 diffuses at a fixed angle to the center axis of a burner in a furnace 18, and primary air 12 is also absorbed to the currents of the secondary air 13 and diffuses. Consequently, a flame 17 widely diffuses in the furnace and is burnt. Thus, a central portion of the flame 17 diffusing in a funnel- shaped form is brought to negative pressure, and one portion of combustion exhaust gas 15 once burnt completely is recirculated toward a burn ignition point as recirculation gas 16. The recirculation gas 16 lowers the concentration of oxygen in combustion air and inhibits the generation or NOx becasue the gas 16 is absorbed and mixed to the primary combustion air 12 and the secondary combustion air 13 having inclinations spreading to the outside when the gas reaches near the burner ignition point.
