Municipal solid waste (MSW) is becoming a concern as population in urban area is increasing. Several disposal methods (landfill and biochemical) have been used. However, waste to energy (WTE) particularly gasification technology is a potential technology for energy recovery. The system is used to convert biodegradable material into syngas under limited gasifying media. This study presents numerical analysis of producer gas for the two air paths in the hybrid fixed bed gasifier (HFBG). It was revealed that the optimum operating condition was achieved when the air ratio at the first air flow path (AIR1) was 0.3. Furthermore, the exergy efficiency of about 81.51% was achieved.
