The role of various biomass feedstocks in the design and optimization of an integrated gasification combined cycle

Abstract

In this research study, a system comprising simultaneous electricity and heat production is selected, simulated, and investigated from the standpoints of energy, exergy, and economics. This integrated energy system is comprised of key components of a gasifier, a gas turbine, a Stirling engine, and a supercritical cycle ofS-CO2 with a water heater. The consequences of cycle coupled with the Stirling engine on system effectiveness and net performance have also been investigated. Various biomass fuels are considered for the comparison. The fundamental and efficient characteristics of the cycle were found by thermodynamic and economic assessment using parametric research, and optimization was then carried out using the target operations of exergy efficiency and expense for wood biomass inside the system. When evaluating both exergy effectiveness andexpense, the most acceptable point of system design leads to exergy effectiveness and expense equal to 0.43 percent and22.79 $/h, respectively. Finally, a multi-objective optimization is carried out to determine the best optimal design parameters.
