Investigation of producer gas biomass gasification on reciprocated internal combustion engine

Abstract

Biomass is sustainable and a source for renewable energy to overcome the limitation of fossil fuel. The research used woody pellet feedstock with 0.79 g/cm3 of bulk density and 6 mm diameter in the syngas production. Therefore, downdraft gasifier reactor with a stainless steel pipe 500 mm length and 120 mm inner diameter produced syngas as producer gas. Reciprocated Internal Combustion Engine (R-ICE) was used to drive the syngas production from biomass gasification process with 1800 rpm ± 20 rpm in constant engine speed. The Indication of Mean Effective Pressure (IMEP) and Excess Air Rate (EAR) were applied as the parameters for analyzing the system. Kawasaki FD750 with single cylinder was implemented to test the effect of syngas instability. Oxidizer and fuel for the engine were mixed in the venture which typed Heinzmann, GM 50 to make homogenous fuel. The laminar flow meter type of Sokken, LFE-25B was adapted to measure the intake air flow rate, and the digital ignition system of Altronic, CD200D was used to control the ignition timing. In conclusion, the synthetic gas (syngas) as the main fuel will not be enough to replicate drive on R-ICE.
