Description

가연성 분말용 연소장치Combustion device for flammable powder
본 발명은 가연성 분말용 연소장치에 관한 것이다.The present invention relates to a combustion device for a combustible powder.
가연성이란 불에 잘 탈 수 있거나 타기 쉬운 성질을 말한다.Flammability refers to properties that can burn well or burn.
가연성 고체에는 종이, 천, 목재, 석탄, 고무, 수지, 황 등의 일반 가연물 및 연료류, 금속류의 일부가 여기에 속하며, 목조건물, 가구, 도장물품 등도 포함된다. Flammable solids include general combustibles such as paper, cloth, wood, coal, rubber, resin, sulfur, and some of the fuels and metals, including wooden buildings, furniture, and painted items.
또한, 가연성 쓰레기에는 유기물로 되어 있는 음식쓰레기, 사체, 분뇨 등이 있다.In addition, flammable trash includes food waste, carcass, and manure which are organic materials.
상기 가연성 쓰레기를 처리하는 방안에는 소각하는 제1방안, 퇴비화하는 제2방안 및 매립하는 제3방안이 있다.Methods for treating the combustible waste include a first method for incineration, a second method for composting, and a third method for embedding.
퇴비화하는 제2방안은 가연성 쓰레기가 음식쓰레기 또는 분뇨인 경우에는 염분이 많아 부적절하고, 그리고 매립하는 제3방안은 침출수가 많이 발생되어 토양과 주변의 하천을 오염시킬 수 있고 매립택지를 마련하기가 어렵다고 하는 문제점이 있다.The second method of composting is that the flammable waste is inadequate due to the high salinity in the case of food waste or manure, and the third method of landfilling is to pollute the soil and surrounding rivers by generating a lot of leachate, There is a problem that it is difficult.
소각하는 제3방안은 한국등록실용20-0199645호에 개시된 바와 같이, 가연성인 음식쓰레기를 건조하여 분말화된 음식쓰레기분말을 공기와 함께 소각로 내의 화염에 투입하여 연소시켜 소각시키고 있지만, 소각로에 구비된 버너의 화염에 의해 음식쓰레기분말을 소각하는 것이어서, 버너의 화염을 제공하기 위한 별도의 기상, 액상 또는 고상 연료가 필요된다고 하는 문제점이 있을 뿐만 아니라, 음식쓰레기분말, 즉 가연성 분말이 화염 주변의 분위기 온도로 인하여 화염 속에 투입되지 못하고 완전연소를 갖지 못하는 화염 주변에서 불완전연소된다고 하는 문제점을 가진다.The third method of incineration is to burn food garbage which is flammable by burning food garbage powder into the flame in the incinerator together with air to burn the food garbage powder by incineration as disclosed in Korean Registration Practice No. 20-0199645, Liquid or solid fuel is required to provide the flame of the burner because the food waste powder is incinerated by the flame of the burner, and the food waste powder, that is, the flammable powder, There is a problem that incomplete combustion occurs around the flame which can not be injected into the flame due to the atmospheric temperature and does not have complete combustion.
또한, 상기 개시된 제3방안은 가연성인 음식쓰레기분말을 송풍기의 날개와 접촉시켜 소각로 내로 공급하기 때문에, 송풍기의 날개가 용이하게 부식 및 손상될 수 있다고 하는 문제점을 가진다.In addition, the third method described above has a problem that the food wastes powder, which is combustible, is supplied into the incinerator by contacting the wings of the blower, so that the wings of the blower can be easily corroded and damaged.
