초록

본 연구는 해군함정에 탑재되어 있는 주 추진 디젤엔진에서 배출되는 입자상 물질, 황산화물, 이산화탄소 및 질소산화물의 배출량 예측에 초점을 두었다. 국제사회 및 각국의 정부는 인간의 건강 및 환경을 보호하기 위해 선박의 배기가스 규제를 엄격히 적용하고 있으며 선박 제작사들은 이러한 법규에 대응하기 위해 다양한 기술을 선박에 적용시키고 있다. 엄격히 적용되는 배기가스 법규는 선박의 크기에 따라 차이를 보이고 있지만 함정은 규제대상에서 제외된다. 다양한 연구결과에 의해 선박의 배기가스 배출량 계수(emission factor)는 지속적으로 최신화되고 있으나 함정의 배출량 계수는 그 특성의 차이 때문에 설정이 어려운 실정이다. 본 논문은 함정 엔진의 연료소모량과 함정에서 사용하고 있는 연료의 황성분 함량을 분석하여 항해 시 선박에 적용되고 있는 오염물질 기여도 조사(emission inventory) 방법론을 해군함정에 적용시켜 정속항해 조건에서 배기가스 총 배출량을 예측하는 것이다.

This study was focused on the estimations of air pollutants, such as PM(Particulate matters), SOx(Sulfur Oxides), $CO_2$(Carbon diOxides) and NOx(Nitrogen Oxides), from a diesel propulsion engine installed on a naval vessel. Legislative and regulatory actions for exhaust emissions from ships are being strengthened in international communities and national governments to protect human health and the environment. In this context, various technologies have been developed from all of the nations of the world to meet strict standards. These regulations are based on commercial ship applications and according to size, but are not suitable for military naval vessels, which have much different engine operating conditions and hull architectures. Additionally, there is no international emission control system for military ships. Emission factors have been updated for commercial ship types from work at various research institutes; however, it is difficult to develop emission factors for military vessels because of their characteristics. In this paper, exhaust emissions from diesel engines installed on naval vessels under steady navigation condition were estimated with emission inventory methodology applied to ocean going vessels using fuel-based methods and fuel sulfur content analysis.
