The results of energy analysis show that with the biomass mixing ratio rising from 0%-30%, the outlet temperature of the combustion chamber increases from 1262.7-1287.1 ℃, while the outlet temperature of the gas turbine increases from 590.2-609.8 ℃. The mass-flow rate of the natural gas drops from 13.92-9.57 kg/s, however, the total mass-flow rate of the fuel increases from 13.92-27.48 kg/s. Additionally, the steam turbine power output changes from 135.84-136.73 MW. The gas turbine power output changes from 254.15-253.26 MW. The results of exergy analysis show that with the biomass mixing ratio rising from 0%-30%, the exergy destruction of the air compressor, combustion chamber, and gas turbine drops. The exergy destruction of the heat recovery steam generator slowly increases from 192.91-193.12 MW. The exergy destruction of the steam turbine is slowly increasing from 155.02-156.2 MW. These research findings offer innovative solutions for the green transformation of industrial energy systems. It can effectively assist designers in optimizing heat recovery steam generator and steam turbine to improve the thermal performance of combined cycle power plant systems coupled with biomass gasification.
