A novel system was developed by combining the alkali metal thermal to electric converter (AMTEC) and biomass gasification. The primary purpose of this study was to examine the feasibility of utilizing the emitted gas caused by biomass gasification as the heat source of the AMTEC device. Key features were studied at constant temperatures under the influence of changes in biomass. These studies were performed on the effects of the equivalence ratio and the fuel flow rate of the biomass system on the total output power, efficiency, and effective voltage of the intended AMTEC. Due to coupling circumstances, ER changes were limited between 0.3 and 0.4. The findings revealed that the equivalence ratio affected the output power, efficiency, and total current of the system reversibly while directly impacting the effective voltage. Increasing the fuel flow rate initially enhanced the efficiency and total output power, but they both were reduced above a specific fuel flow rate. A maximum efficiency of 18.5% was obtained at the optimum fuel flow rate of biomass. More tubes in the cell improved the overall performance of the developed system. However, design and construction cost limit the number of tubes. The results obtained reveal the advantages of the hybrid model.
