Abstract
In this research, the simulation of a biomass power generation system was studied by comparing two processes: biomass combustion coupled with a steam turbine for power generation and biomass gasification coupled with a combined cycle system. The aim was to compare the efficiency of power generation system using sugarcane bagasse and cassava pulp as feedstocks. The simulated process was conducted using the Aspen Plus program to analyze various operating variables, including combustion temperature (800-1,000°C), air-to-fuel ratio (1-10), gasification temperature (800-1,000°C), and steam-to-biomass ratio (0.1-2.0). The results revealed that the most efficient power generation system, yielding maximum total power output and electrical efficiency, was biomass gasification coupled with a combined cycle system. The optimal operating conditions were gasification temperature at 1,000°C and steam-to-biomass ratio of 1. Under these conditions, the total power outputs from bagasse and cassava pulp were 4,995.10 kW and 4,985.08 kW, respectively. Moreover, the electrical efficiencies were 66.88% and 77.43% for bagasse and cassava pulp, respectively. In addition, for biomass combustion coupled with a steam turbine for power generation using bagasse and cassava pulp, the optimal operating conditions were a combustion temperature of 1,000°C and air-to-fuel ratio of 7. This resulted in comparable electricity outputs of approximately 700 kW, with electrical efficiencies of 13.91% and 15.89% for bagasse and cassava pulp, respectively.
