Patent ID: 6969250

Claim:
A waste gas treatment system comprising: a burner part; and a combustion chamber provided at a downstream side of said burner part, wherein combustion flames are formed from said burner part toward said combustion chamber and a waste gas is introduced into the combustion flames, thereby oxidatively decomposing the waste gas, wherein said combustion chamber has an inner wall made of a fiber-reinforced ceramic material comprising ceramic cloth coated with a binder-containing ceramic material, and wherein said burner part has a cylindrical member having a side wall, being closed at a top thereof and having an opening at a bottom thereof, said cylindrical member also having a waste gas inlet in said top thereof and an air nozzle at a predetermined position on said side wall, said cylindrical member further having an auxiliary burning gas nozzle in said side wall in a vicinity of the opening, said air nozzle and said auxiliary burning gas nozzle extend at predetermined angles to a tangential direction to said cylindrical member to blow a swirling air flow and a swirling auxiliary burning gas flow downward against the combustion flames formed downward below the opening.
