This research investigates an integrated gasification combined cycle (IGCC) system utilizing rubber wood sawdust and municipal solid waste pellets as feedstock in a downdraft gasifier. The study aims to evaluate optimal operating conditions that maximize total power and power efficiency. A simulated process was conducted using the ASPEN Plus V.12.1 program to study various operating variables, including gasification temperature (700-1200°C), steam to biomass ratio (S/B) (0-1), and compression ratio (14-22). The results reveal that increasing the gasification temperature resulted in a reduction in the syngas compositions of H2, CO2, and CH4, while CO and steam increased. In addition, increasing the steam to biomass ratio (S/B) resulted in higher H2, CO2, and steam in the syngas, while CO and CH4 decreased. H2 and CO were identified as the primary syngas compositions for power generation. For the generation of high total power, the optimal operating conditions were found to be a gasification temperature of 1200°C, an S/B ratio of 1, and a compression ratio of 14. Under these conditions, the total power output from rubber wood sawdust and municipal solid waste pellets was 5.55 MW and 5.30 MW, respectively. Moreover, for achieving high power efficiency, the optimal operating conditions were determined as a gasification temperature of 1200°C, S/B ratio of 0.2, and a compression ratio of 14. The power efficiency for rubber wood sawdust and municipal solid waste pellets was 31.85% and 38.49%, respectively.
