Emission Characteristics of a Small Size Industrial Gas Turbine Combustor with Varying Methane Concentrations in Fuel

연료 메탄 농도 변화에 따른 발전용 소형 가스터빈 연소기 배기성능 평가

Since gas turbine using biogas can reduce carbon dioxide ($CO_2$), the biogas gas turbine is becoming more attractive to renewable energy utilization business sector. Natural gas and $CO_2$ mixture was used to simulate the biogas fuel. At the experiments pressure losses, pattern factor, and emissions were measured. The results revealed that methane concentrations of the fuel mixture showed little effects on the combustor performance except emissions. As methane concentrations in fuel decreased, emissions measured at the exit of the combustor decreased.
