Abstract
In this work, a detailed thermodynamic analysis is performed on a solid oxide fuel cell-gas turbine combined system. The fuel input to the fuel cell is the synthetic gas produced from the gasification of municipal solid waste. The efficiency and output power of the system are calculated and the system is analyzed for its performance by variation of parameters which includes compression ratio, fuel utilization factor and current density. The work is done based on the Municipal solid waste generated in Indian cities. Destruction of exergy is calculated from exergy analysis. System is modelled using flow sheeting program Cycle Tempo®. Components contributing to major exergy destruction are combustor and fuel cell. Energy efficiency of 44.5%, exergy efficiency of 39.2% and a power output of 170 kW is obtained in this system. This CHP system is very much acceptable for restaurants, shopping complex and other small-scale applications where power requirement is less.
