Abstract

To replace waste oil with the lowest grade which has high viscosity into heating fuel, light oil and buncker C oil in waste oil was used and the fuel characteristic was analyzed by its concentration after mixing oil. The mixture conditions were controlled by the reaction time (30 s~30 min) and kept by the reaction temperature ($75{\pm}5^{\circ}C$) when mixing speed was stirred at 3400~3600 rpm. We used the buncker C oil and light oil to decrease viscosity of waste oil and the dynamic viscosity was decreased by 81~96%. Optimum mixing ratio (waste oil : buncker C oil : light oil) as heating fuel was 1 : 1 : 1. Flash point, dynamic viscosity and heating value of this case were identified $78^{\circ}C$, $20.02mm^{2}/s$, 9158 kcal/L respectively.

고점도인 최저급 폐유를 난방유로 대체하기 위하여 폐유에 희석용제로 경유,벙커C유를 이용하여 일정비율로 혼합한 후 연료 특성을 분석하였다. 혼합조건은 교반속도 3400~3600 rpm에서, 반응 시간을 30 s~30 min으로 조절하였고 반응온도는 $75{\pm}5^{\circ}C$로 유지하였다. 벙커C유, 경유를 이용하여 폐유의 점도를 낮춘 결과 최소 81%, 최대 96% 정도 감소되었다. 난방연료로서 폐유 : 벙커C유 : 경유의 최적 혼합 비율은 1 : 1 : 1이었으며 이 경우 인화점 $78^{\circ}C$, 동점도 $20.02mm^{2}/s$, 발열량 9158 kcal/L을 가짐을 확인하였다.
