Recently, technologies and policies to secure energy using waste resources have been actively promoted to reduce greenhouse gas emissions due to resource depletion and climate change, and developed countries such as Europe and Japan are trying to recover energy contained in waste. In other words, the expansion of fuel (mechanical biological treatment) or MBT (mechanical biological treatment) facilities, which are the production technology of SRF (Solid Refuse Fuels), is increasing.
특히, 온실가스 저감을 위해 폐기물을 연료로 회수하여 에너지로 활용하는 시장이 급속히 확대되고 있으며, 이에 폐기물에 포함된 불연물(타지않는 물질)을 선별하고, 수분을 저감시켜 발열량을 높여, 에너지 효율을 향상시키기 위한 연료화 공정의 개발과 이를 적용한 사업이 활발히 추진되고 있다.In particular, the market for recovering wastes as fuel and using them as energy to reduce greenhouse gases is rapidly expanding. Therefore, non-flammables (unburned substances) contained in wastes are sorted, and moisture is reduced to increase heat generation and energy efficiency. Development of fueling process to improve and projects applying it are being actively promoted.
폐기물 연료화 사업은 기존의 일괄적인 소각 열 회수 방식을 벗어나 화석연료를 대체하고, 자원의 효율성을 높일수 있고, 폐기물 매립장의 사용연한을 증가시키는 등 긍정적인 측면에서 정책적으로 추진되고 있다.The waste fueling project is being promoted in a positive manner, replacing the existing incineration heat recovery method, replacing fossil fuels, increasing the efficiency of resources, and increasing the service life of waste landfills.
하지만, 대부분의 폐기물의 연료화 시설에서는 폐기물의 수분을 저감시키는 건조기가 포함되어 있으며, 필요에 따라서 펠렛(Pellet)형태로 제조하는 성형기와 재활용품와 불연물 등을 인력으로 선별하는 수작업 선별공정이 불가피하게 된다. However, most waste fueling facilities include a dryer to reduce the moisture of the waste, and if necessary, a manual sorting process for sorting the molding machine and pellets produced in pellet form and recycling and non-flammable materials is inevitable.
이처럼 기존 연료화 생산 공정은 프로세스가 복잡하고, 회수 효율이 낮아 고형연료(SRF)로 생산되는 제품 회수율이 비성형(Fluff) 기준으로 60% 내외로 낮다는 문제점이 있다.As such, the conventional fueled production process has a problem that the recovery rate of the product produced by the solid fuel (SRF) is low around 60% on the basis of the non-molding (FRF) due to the complicated process and low recovery efficiency.
또한, SRF에 포함된 수분을 저감시키기 위해 LNG 등의 화석연료를 이용한 열풍건조 방식을 사용함으로써, 건조에 소요되는 에너지 비용이 전체 고형연료화 공정에 소요되는 에너지 비용의 50% 이상을 차지할 정도로 건조비용이 증가하는 문제도 있었다.In addition, by using a hot air drying method using fossil fuels such as LNG to reduce the water contained in the SRF, the drying cost is such that the energy cost of drying takes up more than 50% of the energy cost of the entire solid fuel conversion process. There was also an increasing problem.
또한, 통상적으로, 연료화 공정에는 수분을 저감시키기 위해 건조장치가 설치되나, LNG 등의 화석연료 사용으로 인해 전체 연료화 공정의 사업성을 악화시키는 요인으로 작용하고 있다는 문제점도 있었다.In addition, although a drying apparatus is usually installed in the fuelization process to reduce moisture, there is also a problem that the use of fossil fuels such as LNG deteriorates the feasibility of the entire fuelization process.
