Abstract

In this paper, Gas engine was tested for the energy of synthesis gas. As excess air ratio increase 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 in 1800 rpm and synthesis gas, thermal efficiency generally decrease and power generation was 34 kWm at λ 1.4. And excess air ratio increase 1, 1.1, 1.2, 1.3, 1.4 in power generation 34 kWm, thermal efficiency generally increase 34.2%, 36.9%, 37.2%, 37.4%, 38.1%. Total efficiency through power generation consumes 38.7 kg/h of fuel at 30 kWe load and recovers 57.3% of waste heat by recovering 57.3 kW of waste heat through 32.1% power generation efficiency and heat recovery from cooling water and exhaust gas. The total efficiency was 85.8%.

본 연구에서는 합성가스의 에너지화를 위한 가스엔진 성능 평가를 수행하였다. 회전수 1800 rpm 조건에서 공기과잉률이 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 증가에 따른 엔진출력(kWm)과 열효율(%)을 평가한 결과, 공기과잉률 λ 1.4에서 엔진출력 34 kWm를 나타냈으며, 공기과잉률이 증가할수록 엔진 열효율은 전반적으로 감소하는 경향을 보였다. 엔진출력 34 kWm 조건에서 공기과잉률이 1, 1.1, 1.2, 1.3, 1.4 증가시 열효율이 34.2%, 36.9%, 37.2%, 37.4%, 38.1%로 증가하였고, 발전출력을 통한 종합효율은 발전출력 30 kWe 부하조건에서 38.7 kg/h의 연료를 소모하여 32.1%의 발전효율과 냉각수와 배기가스에서의 열회수를 통해 57.3 kW의 폐열을 회수하여 53.8%의 열을 회수하여 총 85.8%의 종합효율을 보이는 것으로 나타났다.
