재생 가능 에너지 원은 산업에서 온실 가스 배출을 줄이기 위한 방벙 중에 하나이다. 그러나 이러한 에너지원은 대한 다양한 분야에 활용하는 기술은 부족하다. 이들 중 열전 발전은 어업에 적용될 수 있다. 엔진 점화 과정 후, 발생하는 폐열을 재활용하는 것은 에너지 원 일뿐만 아니라 온실가스 배출을 감소시킬 수 있다. 따라서 본 연구는 폐가스로 인한 발전 가능성을 검증하고 성능을 분석하기 위해 고안되었다. 설계된 실험 장치는 데이터 로거 및 전기부하기와 연결되어 전류 및 전압을 측정하였다. 열전발전 장치는 연안자망어업을위한 연안 어선에 설치되었다. 전체 어업과정 중, 발전량은 엔진 rpm에 의해 측정되었다. 선박 운영을 포함한 어업 운영 절차. 실용적인 범위에서 최대 1500rpm에서 발생량은 113.6 와트였다. 결선방법에 따라 발전량 차이는 5 와트 이내였다. 직렬 연결은 111.4 와트이고 병렬 연결은 115.84 와트였다.
Abstract
The renewable energy sources can be thought of one of the major measures to reduce greenhouse gas emissions in the industries. However, the utilization technology for those sources is approaching in the different matters. One of them, thermoelectric generation might be applicable to fishing industry. A various of internal combustion engines are used in a wide range of fisheries. After the ignition process, the heat passed out from the exhaust outlet. Recycling the heat could be not only an energy source but also reduction of green gas emission. Therefore, this study was designed to verify the feasibility of generation from wasted exhaust gas and analyze the performance. The designed experiment devices were connected with a data logger and an electric loader to quantify the currency and voltage. The devices were installed in a coastal fishing vessel for a gillnet fishery. During the whole fishing trips, the amount of generation was measured by engine rpm and the fishing operation procedures including vessel operations. At the maximum 1,500 rpm in the practical range, the generation amount was 113.6 W. The amount difference in relation to connection method was within 5 W: serial connection was 111.4 W and parallel connection was 115.8 W.
