초록

본 연구에서는 OIMS90과 NP12 계면활성제 혼합물을 사용하여 물/벙커 C 오일 비율, 계면활성제 농도 및 조성, 유화 시간, 교반 속도 및 시간, 온도 등을 변화시키면서 유중수적형(water-in-oil, W/O) 에멀젼 연료를 제조하였다. OIMS90과 NP12 계면활성제 혼합물을 사용하여 제조한 에멀젼 연료는 벙커 C 오일에 비하여 미세먼지, $NO_2$, CO, $CO_2$ 및 $SO_2$ 등의 연소배기 가스 중의 대기 오염물 방출을 감소시키는데 효과적이며, 특히 계면활성제 조성 OIMS90/NP12 = 4 : 6, 계면활성제 농도 500 ppm, 수분 함량 10%을 사용하여 $80^{\circ}C$에서 제조한 에멀젼 연료가 배기가스 오염물 저감 효과가 가장 큰 것을 확인하였다. 또한 보일러 효율 측정 시험 결과, 에멀젼 연료가 벙커 C 오일과 비교하여 우수한 디젤 엔진 에너지 효율을 나타내었다.

In this study, water in oil (W/O) emulsion fuel was prepared with surfactant mixture of OIMS90 and NP12 by varying ratio of water to bunker-C oil, surfactant concentration and composition, emulsification time, stirring intensity, temperature and mixing time. Diesel engine performance and exhaust emissions were measured and analyzed with prepared emulsified fuel and compared with those measured using bunker Coil. The results indicated that bunker C emulsion fuel stabilized by surfactant mixture of OIMS90 and NP12 is efficient in reducing emissions of particulate matter, $NO_2$, CO, $CO_2$ and $SO_2$. The biggest reduction in exhaust emission was achieved by using emulsion fuel prepared by OIMS90/NP12 = 4 : 6, 500 ppm of total surfactant concentration and 10% water content at $80^{\circ}C$. Boiler efficiency test measured with emulsion fuel showed excellent energy efficiency compared with bunker C oil.
