초록

본 연구에서는 자원 재활용-에너지에 바탕을 둔 돈분, 계분, 혼합물의 연소특성에 대하여 고찰하였다. 시험편은 건조 오븐을 이용하여 항량까지 건조시킨 후에, 콘칼로리미터(ISO 5660-1)를 이용하여 연소성질을 시험하였다. 그 결과 돈분의 최대유효연소열(78.72 MJ/kg)은 계분(69.41 MJ/kg)과 비교하여 탄화수소의 많은 양 때문에 비교적 증가했다. 또한 돈분의 $CO_2$ 발생속도(0.1959 g/s)와 총연기발생률($419m^2/m^2$)도 각각에 대하여 계분보다 증가하였다. 반면에 계분의 CO 발생량(0.0996 kg/kg)과 CO 발생속도(0.0034 g/s)는 계분이 함유하고 있는 많은 무기물 함량 때문에 각각 돈분보다 높았다. 따라서 높은 연소 에너지는 탄화수소 함량에 의존하여 발생되는 것으로 판단된다.

In this work, the combustive properties of the swine manure, poultry manure, and mixtures based on the resource recycling-energy were investigated. After the specimens were dried to a constant weight by dry oven, combustive properties were tested by the cone calorimeter (ISO 5660-1). It was found that the peak effective heat of combustion (PEHC) in the swine manure (78.72 MJ/kg) has risen due to more amount of the hydrocabon compared with poultry manure (69.41 MJ/kg), also the swine manure increased both of the higher $CO_2$ production rate (0.1959 g/s) and total smoke release rate (THRR) ($419m^2/m^2$) than those of the poultry manure. However, both of the CO production release (0.0996 kg/kg) and CO production rate (0034 g/s) in the poultry manure increased due to more amount of the inorganic contents compared with swine manure. Thus, the high combustion energy is expected to generate depend on the hydrocarbon content.
