Energy and exergy analysis of combined power cycle integrated with biomass gasifier for power production

In this paper, the thermodynamic first law and second law analysis of combined power cycle are conducted. Energy and exergy distribution of biomass in the proposed cycle are shown. A parametric analysis is performed to investigate the effects of change in biomass material, gas turbine inlet temperature and steam turbine inlet pressure on performance of the topping integrated gasification combined cycle (IGCC). The results show that both first and second law efficiencies increases considerably with the increase in gas turbine inlet temperature and decreases with the increase in steam turbine inlet pressure.
