초록

대기오염으로 인한 기후변화, 에너지 자원의 고갈 및 에너지 안보 등의 이유로 세계 각국에서는 신재생 에너지 연구 개발에 국가적 노력을 아끼지 않고 있다. 신재생 에너지 중 바이오디젤 연료는 기존의 디젤연료를 대체할 친환경 에너지로써 각광을 받고 있으며, 일정한 비율로 디젤연료와 혼합 시 기존 디젤기관의 개조 없이 사용가능하다. 다양한 연구결과에 의해 선박의 배기가스 배출계수는 지속적으로 예측되고 있지만 특수선박으로 분류되는 함정의 배출계수 연구결과는 부족한 실정이며, 특히 바이오디젤 혼합 연료에 대한 배기가스 배출계수는 함정뿐만 아니라 선박에서도 연구 실적이 부족한 상황이다. 본 논문에서는 해군함정에 탑재되어 있는 추진 디젤기관에 바이오디젤 혼합 연료를 적용시켰을 때 배출되는 이산화황 및 이산화탄소의 배출계수를 연료성분 분석 결과를 이용하여 구하고, 연료소비율 계산을 통하여 배출량을 정량적으로 예측하였다.

National investment was performed in the research and development of renewable energy because of climate change by air pollution, exhaustion of energy sources, energy security, and so on. Biodiesel fuel of the renewable energy is highlighted as friendly environment energy, it is possible to operate in regular diesel engines when it is blended with invariable ratios without making any changes. Emission factors have been estimated for commercial ship from various research institutes; however, it is difficult to develop emission factors for military vessels. In this work, biodiesel blended fuel emission factors for sulfur dioxide and carbon dioxide were quantitatively estimated from propulsive diesel engine installed on naval vessel using fuel property analysis. In addition, exhaust emissions were quantitatively calculated on the basis of fuel consumption rate with biodiesel content by percentage.
