摘要：
This study deals with the energetic analysis of a combined heat and power (CHP) system installed in Eskisehir City of Turkey. The mass and energy balance relations are derived and applied to the components of CHP system and overall CHP system. The performance characteristics of this CHP system are evaluated in terms of energetic aspects. Considering total output energy, the total energy efficiencies (electrical and thermal) of gas turbine cycle, heat recovery steam generator(HRSG), steam cycle and CHP system are 95.3 %, 83.56 %, 76.7 % and 79.3 %, respectively. Based on total useful energy output (excepting the stack gas, waste boiler loss, condenser line, medium pressure steam collector energies), the total useful energy efficiencies of gas turbine cycle, HRSG, steam cycle and CHP system are 82.3 %, 65.2 %, 18.5 % and 40.02 %, respectively.
