Abstract
The invention discloses an oven head of gas appliance by burning low nitrogen oxides. Fire covers of outer and inner rings are set on the oven head and the oven head is set on the furnace disc. The furnace disc is set on the base of oven head, on which a first and second air supply pipes are set. Central circular fame is set on the fire cover of inner ring. A first, second and third ring flames are set on the fire cover of outer ring in turn and relative to them a first, second and third ring air supply grooves are set on the oven head. By several nozzles, which can control fuel consumption, the second flame jets burning gas. Air supply is enough at one time in burning. The side of the first and third ring flames back to the second ring flame can obtain a second time air and the side near the second ring flame can not obtain the second time air. In this way, the first and third ring flames are drawn out and longer flame prolongs the burning and heating time so that the flame temperature decreases and oxinitride is controlled to generate efficiently. So the invention can decrease the discharge quantity of oxinitride indeed.
