80 kW Updraft Gasifier Performance Test using Biomass Residue Waste from Thailand Rural Areas

Abstract

This research presents the combustion test of Kanchanaburi’s residue waste used in an 80kW updraft gasifier as biomass fuel. Three types of selected biomass were considered: corncob, bagasee, and straw. The 80kW updraft gasifier was designed, fabricated, and experimentally studied. In the gasifier, a variable speed centrifugal fan acted as a forced convection unit, which was installed near the combustion chamber and transferred air volume to the updraft gasifier stove. The experimental results show the temperature in each zone of the thermochemical processes. The gasifier was evaluated by comparing the performance of the 3 different biomass fuels. The average producer gas from the burning of corncob, bagasee, and straw was 2.31m3/kg, 2.15m3/kg, and 2.11m3/kg respectively in the updraft gasifier. The recorded stove running times (h) for were 1.24, 1.2 and 1.05, respectively. The producer gas can be used to run a local cooking stove kiln with at normal rated heat generation successfully.
