Abstract:
A burner for treating a waste gas, characterized in that:a flame stabilizing zone is open toward a combustion chamber, surrounded by a peripheral wall, and closed by a plate remotely from said combustion chamber; a waste gas flame hole is disposed on said plate for ejecting the waste gas toward said flame stabilizing zone; an auxiliary combustible gas flame hole is disposed on said plate for ejecting the auxiliary combustible gas, and an air ejection nozzle is disposed on the peripheral wall of said flame stabilizing zone for ejecting air substantially circumferentially to produce a swirling flow; wherein said waste gas, an auxiliary combustible gas, and air are introduced into and mixed with each other in said flame stabilizing zone, and the mixed gases are ejected toward said combustion chamber perpendicularly to said plate; said burner characterized in that: said waste gas flame hole and auxiliary combustible gas flame hole are arranged in a substantially circumferential pattern of an annular shape substantially around the center of said flame stabilizing zone; said auxiliary combustible gas flame hole is disposed adjacent to said waste gas flame hole in said annular shape; and said annular shape is in same position with a free vortex region of said swirling flow.
