Abstract

In these days, many countries carry out many renewable energy policies to increase the renewable energy portion and to reduce the GHG(Green House Gas). In Korea, RPS(Renewable Portfolio Standards) focused on over 500MW power producers is conducting. And they are using the bio-fuel oil to meet their RPS quota. The oil is a mixture of animal and vegetable fat or fatty acid ester of them and should satisfy some specifications to use the power generation such as viscosity, pour point, acid number. Depends on the raw materials, quality characteristics of power bio-fuel oil are changed. By adding the power bio-fuel oil, pour point, density, sulfur content and viscosity are decreased and acid number, iodine number, oxygen content are increased. In this study, we test the quality characteristic of power bio-fuel oil and the property changes by the blending ratio of power bio-fuel oil & conventional fuel oil.

전 세계적으로 에너지원 다양화 및 온실가스 저감을 위한 다양한 신재생에너지 보급활성화 정책이 추진되고 있다. 국내에서도 500MW 이상의 발전설비를 보유한 발전사업자에게 신재생에너지 공급 의무화제도(Renewable Portfolio Standard(RPS))를 시행중이다. 발전사업자들은 의무공급량 이행을 위해 발전용 바이오중유를 사용하고 있다. 발전용 바이오중유란 동 식물성 유지, 지방산에스테르 및 그들의 혼합물로서 동점도, 유동점, 전산가 등의 품질특성을 만족해야 한다. 발전용 바이오중유는 원료물질에 의해 품질특성이 결정되었고, 중유와의 혼합비율이 증가할수록 유동점, 밀도, 황분 및 동점도는 감소하고 전산가, 요오드가, 산소함량은 증가하였다. 본 연구에서는 중유 대체연료로서의 발전용 바이오중유의 품질특성과 C 중유에 혼합 시, 혼합비율에 따른 물성 변화에 대해 검토하였다.
