본 연구는 B시 생활폐기물 및 유기성 폐기물의 혼합에 따른 연료화 및 활용방안에 대한 연구를 진행하였다. 반입폐기물, sludge cake와 food wast의 모든 혼합비율의 발열량이 6,000 kcal/kg으로 산출되었고, sludge의 경우 공연비와 온도가 높을수록 발생되는 유해물질 농도가 낮은 것으로 나타났다. 유해물질의 배출기준과 비교하여 보았을 때, 공연비가 2인 경우 800$^{circ}C$일 때 유해물질 (CO, NOx, SOx)들이 기준이하의 배출 농도를 나타내었으며 혼재 소각 시 소각로 내부 온도 또한 가장 안정되는 것으로 나타났다. 소각시 완전연소가 이루어진다면, 혼합하여 RDF를 제조 시 발열량이 6000 kcal/kg이상으로 연료화 하기에 적합한 것으로 나타났다.
This study was conducted to examine the possibilities to utilize the mixture of domestic and organic wastes from B-city as a fuel. All types of mixing ratio for uncarried waste, sludge cake, and food waste were found 10 generate heating value with 6,000 kcal/kg, and in case of sludge cake the concentration of toxic substance produced was found to be decreased as air-fuel ratio and temperature were increased. It was noted that toxic gases such as CO, NOx, and SOx were observed below concentration of emission standard, and temperature inside the incinerator was stabilized at 2 of air-fuel ratio and 800$^{circ}C$. It was observed that a heating value of 6000 kcal/kg generated using RDF(Refuse Derived Fuel) was appropriate to utilize a fuel if a complete combustion was attained.
