초록

가솔린 엔진에서 개조된 가스 엔진에서 발생하는 냉각수와 배기가스를 분석하여 복합발전 시스템에서 활용 가능한 폐열의 양과 질을 확인하였다. 엔진 배기가스의 온도는 $573.8^{\circ}C$이고, 엔진 출구 냉각수의 온도는 $85.7^{\circ}C$이고, 폐열의 양은 엔진 냉각수가 배기가스에 비교하여 두 배 수준이었다. 두 가지 폐열의 상이한 온도와 양에 대응하는 유기랭킨사이클 (Organic Rankine Cycle: ORC) 발전시스템을 설계하고 열역학적 분석을 수행하였다.

The amount and quality of waste heat from a gas engine which is modified from an automobile gasoline engine is analyzed. Exhaust temperature is $573.8^{\circ}C$ and engine cooling water exit temperature is $85.7^{\circ}C$. The amount of waste heat of engine cooling water is double compared to that of exhaust gas. Organic Rankine cycle (ORC) system is designed for two different waste heat source of engine cooling water and engine exhaust and is thermodynamically analyzed.
