The Effect of Fuel Type on Temperature Profile within Pilot-Scale Downdraft-Gasifier for the LPG Replacement in Electricity Production

Abstract:

This research presents the effect of fuel type on temperature profile within the pyrolysis-, combustion-and reduction-zone of the pilot-scale downdraft gasifier, and the replacement potential of LPG with syngas for electricity production. The experimental results showed that gasification of different fuels have the distinctions of temperature level in each zone. More stable syngas production was obtained either from wood chips (WC) or plastic carrier bag (PCB). In contrast, gasification of aluminum coated plastic bag (ACPB) showed the unsatisfied syngas. From the operation with the dual mode of LPG and syngas for electric production, LPG consumption was reduced about 27.08%, 14.58% and 8.33% when PCB-, WC-and ACPB-syngas were used, respectively.
