A reducing agent injector is provided to inject a reducing agent into a combustion room uniformly, thereby maximizing the efficiency in removal of nitrogen oxides, by installing a triple-pipe type injector passing through a wall of the combustion room. A reducing agent injector(14) injects a reducing agent into a combustion room, wherein the reducing agent reacts with nitrogen oxides contained in a combustion gas. The injector is installed such that the injector penetrates both walls(9) of the combustion room. The injector comprises a reducing agent supply pipe(10) having a plurality of injection nozzles(11), a cooling water supply pipe(12) for wrapping the reducing agent supply pipe, and a cooling water discharge pipe(13) communicating with the cooling water supply pipe and wrapping the cooling water supply pipe. The injection nozzles pass through the cooling water supply pipe and the cooling water discharge pipe to be exposed to an outside of the cooling water discharge pipe.

본 발명은, 악취와 공해를 유발하는 저열량 가스의 완전연소를 위한 다공 분사구가 형성된 저열량가스 연소기와 그 연소방법에 관한 것이다. 일반적으로 저열량 가스는 보조연료를 사용하여 약 800℃ 내외의 연소온도에서 연소시키게 된다. 그러나 일반 연소기에서는 고온의 연소분위기 온도에서도 가연성분의 농도가 낮은 저열량 가스는 착화가 어려워 완전연소 시키기 어려운 단점이 있다. 따라서 저열량 가스의 예열과 착화가 쉽도록 연소기 구조를 개선한 장치이다. 연소실은 이중벽으로 형성되어 바깥벽에는 단열재가 충진되고 안벽에는 다공의 분사구가 설치된 형태의 공기층으로 구성된다. 상기 공기층의 분사구 설치위치는, 연소실내의 보조연료버너의 화염생성 위치에 저열량 가스가 고속으로 유입되도록 하였다. 보조연료는 저공기비로 환원성 분위기에서 연소가 이루어지며, 여기에 산소농도가 높은 저열량 가스를 고속 공급함으로서 저열량 가스의 착화가 용이하고 연료와 공기의 혼합성이 향상된다. 저열량가스, VOC, 폐가스, 연소기, 저공기비

PURPOSE: A two step combustional type waste tire incinerator induces the complete combustion of a waste tire and restrains the generation of exhaust gas by extending the detention period of combustion of the waste tire. CONSTITUTION: A two step combustional type waste tire incinerator comprises a storehouse(1), a compressor(2), a drier(3), a first incinerator(7), a second incinerator(8) and collectors(9,10). The waste tires are burned by a two step combustional type, thereby making a complete combustion. Further, powder state waste tire is induced in spiral type along the inner periphery surface of the incinerators(7,8), thereby minimizing an ash component and extruding pure air where toxic components have been filtered. Therefore, the combustion efficiency of the waste tire is maximized.
