Burnup type removal damage device and burner null for burnup type removal damage device

摘要

PROBLEM TO BE SOLVED: To provide a combustion noxious substance removing device to remove various noxious gases with high-efficiency for a long time and to provide a burner to form an effective flame for combustion noxious substance removal and facilitate cleaning of a nozzle part. ;SOLUTION: This device comprises a combustion cylinder 3 to close one end by a cover body and have the other end opening connected to a cooling cylinder 2; a gas to be treated introduction nozzle 4 situated at the cover body; and a pilot burner 6; and a main burner 5 to effect combustion and/or thermal decomposition of gas to be treated. The main burner 5 is an annular body provided on an inner peripheral surface with a fuel gas injection nozzle and an injection nozzle for assisting gas necessary for fuel combustion. The combustion cylinder 3 consists of axially disposed peripheral wall bodies 31-33, and the main burner 5. The peripheral wall bodies 32 and 33 have an inner wall 34 formed of a porous material, a feed pipe 37 for combustion assisting gas for oxidation is connected to an outer wall 35, and combustion assisting gas for oxidizing gas to be treated is injected in a combustion cylinder through the inner wall 34.;COPYRIGHT: (C)2001,JPO
