바이오중유 적용에 따른 선박용 엔진의 성능 및 배출가스, 부식 특성에 관한 연구
길기현,이민호,정진도 대한기계학회 2023 大韓機械學會論文集B Vol.47 No.1
As the interest on environment pollution has been gradually increasing at home and abroad, fuel and engine researchers have been working on the exhaust and greenhouse gas emission reduction from engines through several approaches such as new device design, innovative after-treatment systems for example, scrubber, SCR, and DPF, clean (eco-friendly alternative) fuel usage, and fuel quality improvement. In this study, the characteristics of performance, exhaust emissions, and metal corrosion when biofuel oils are used in marine engines was studied. Compared with heavy oils, biofuel oils have excellent environmental improvement effects such as reducing sulfur oxides, PM, Co, THC, and greenhouse gases in the exhaust gas. Therefore, biofuel oil must be reviewed as a marine and industrial alternative fuel to cope with the regulation of sulfur content, PM, and reduction of greenhouse gases. 국내·외에서 환경오염에 대한 관심은 급격히 증가하고 있으며, 연료 및 엔진 연구자들은 새로운 장치의 설계 및 획기적인 후처리장치(스크러버, SCR, DPF 등), 클린연료(친환경 대체연료), 연료 품질 개선 등 다양한 접근을 통해 엔진으로부터 배출가스나 온실가스를 줄이기 위해 노력하고 있다. 본 연구에서는, 바이오중유를 선박용 엔진에 사용하였을 때 성능 및 배출가스, 금속 부식 특성에 대해 연구를 진행하였다. 중유 대비 바이오중유는 배출가스에서 황산화물 및 입자상물질, 일산화탄소, 총탄화수소, 온실가스 등 훌륭한 환경 개선 효과를 보여주고 있다. 이러한 결과를 통해서, 황산화물 및 입자상물질(black carbon) 규제 및 온실가스 감축의 관점에서 선박 및 산업용 대체연료로서 바이오중유에 대한 검토가 필요하다고 할 수 있다.

This is a thesis about the experiment of comparison characteristic of exhaust gas in the same condition between diesel engine that is equipped response power 200HP turbocharger to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment with natural aspiration diesel engine and turbocharger diesel engine, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is much higher than the other one. In other hand, in exhaust gas experiment, turbocharger model exhausts more NOX and O2, but it doesn’t significantly affect the result when it comes with decreasing of CO2 and effectiveness of increased power characteristic. As a result, the turbocharger diesel engine is economically effective comparing with the natural aspiration diesel engine.

This is a thesis about the experiment of comparison characteristic of exhaust gas in the same condition between diesel engine that is equipped turbocharger to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment turbocharger diesel engine according to response power, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is almost the same in four turbocharger. In other hand, in exhaust gas experiment, high response power turbocharger model exhausts less NOX, but it doesn’t significantly affect the result when it comes with decreasing of CO2 and effectiveness of similar power characteristic. As a result, the high response power turbocharger diesel engine is economically effective comparing with the low response power turbocharger diesel engine
