BURNER AND AFTERTREATING DEVICE OF EXHAUST GAS

摘要

PURPOSE: A burner for reducing the harmful material from the exhaust gas and a harmful material reducing device comprising the same are provided to enable the temperature of the exhaust gas to uniformly raise without the increase of the inner back pressure since flame is protected by a flame protecting pipe and the exhaust gas and the flame are mixed in a longitudinal direction. CONSTITUTION: A burner for reducing the harmful material from the exhaust gas comprises a combustion chamber, an exhaust gas pipe(120) and a flame protecting pipe(130). A flame forming unit and an outlet unit are formed on one side and the other side of the combustion chamber. The flame forming unit comprises an exhaust gas inlet unit, a fuel injecting nozzle and an ignition unit. An exhaust gas flow pipe is communicated with the exhaust gas inlet unit in the combustion chamber. A plurality of hollow portions, out of which the exhaust gas flows, are formed on the outer circumferential surface of the exhaust gas flow pipe. The flame protecting pipe is communicated with the flame forming unit in the combustion chamber.
