A new biomass hydrogen-power cogeneration system based on the coupling of gasification and pyrolysis was proposed to address the issue of low conversion efficiency of biomass energy. In this system
the syngas produced by biomass gasification and pyrolysis drives a gas turbine to generate electricity
and then the waste heat in exhaust gas of the gas turbine was used to heat feed water into high-temperature steam
which drives the high-pressure and low-pressure steam turbines to generate electricity. The system was simulated using the thermodynamic simulation software Aspen Plus
and the simulation results were subjected to thermodynamic analysis
economic analysis
sensitivity analysis
and environmental analysis. Results show that the net power of the system is 8 061.07 kW
the thermal efficiency is 49.27% and the total exergy efficiency reaches 45.98%. The payback period of the system is 4.80 years and the net present value is estimated to be 630.555 9 million yuan.
