증기분사가 바이오가스를 이용한 가스터빈 열병합 시스템에 미치는 영향

초록

Several MW-class gas turbines are suitable for application in medium-size combined heat and power systems such as community energy systems(CES). Recently, biogas is acknowledged as an alternative energy source, and its use in gas turbines is expected to increase. Steam injection is an effective way to improve performance of gas turbines. This study intended to examine the influence of steam injection on a gas turbine CHP system using biogas as the fuel. A commercial gas turbine of 6 MW class was used. The primary concern of this study is a comparative analysis of system performance in a wide biogas composition range. In addition, the effect of steam temperature and injected steam rate on gas turbine and CHP performance was investigated.
