Abstract

Abstract: This study investigated the effect of equivalent ratio on thermal energy and exhaust gas properties obtained from gasification of oil palm empty fruit bunch by using a household gasifier. The fixed bed household gasifier was designed, fabricated and tested. The chopped oil palm empty fruit bunch (EFB) was used as feedstock and its feeding rate was fixed at 11 kg/hr. The studied equivalent ratios (ERs) of air were 0.1, 0.3, 0.5, 0.7, and 1, respectively. Then, the flame temperature of syngas firing and flue gases properties were determined. The results obtained from study showed that the gasification process was obtained if the ERs were 0.3 and 0.5. When the gasifier was operated at ERs of 0.7 and 1, the process was changed to be combustion. At ER of 0.5, it was the suitable condition for fixed bed gasifier due to this condition provided low ash content, low carbon monoxide, and moderate thermal energy.
