Effects of fuel composition on the economic performance of biogas-based power generation systems

Biogas to fuel is an attractive method to reduce global warming potential of methane emission and providing a renewable source of energy. In this study, exergoeconomic assessment of a biogas-based gas turbine system with preheater is conducted. In the present work, effects of fuel composition on the...
