Burner for treating waste gas

A burner for treating a waste gas, comprising:

• a flame stabilizing zone opened toward a combustion chamber, surrounded by a peripheral wall, and closed by a plate remotely from said combustion chamber;
• a waste gas flame hole disposed on said plate for ejecting the waste gas toward said flame stabilizing zone;
• at least one auxiliary combustible gas flame hole disposed on said plate for ejecting the auxiliary combustible gas, and
• at least one air ejection nozzle 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;
• and
• wherein 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.
