Biomass Gasification Utilization for Double-chambered Crematory

Abstract

Cremation is a tradition that Buddhist and Brahmin people usually perform on the deceased according to their beliefs and local customs. Old-fashioned crematories using wood or charcoal as fuel cannot prevent emission release, which affects people's health and quality of life. On the other hand, the modern, double-chambered crematory, which uses fossil fuel such as diesel or LPG, has presented high operation costs. Thus, this research aims to study the feasibility and possibility of biomass gasification utilization in the cremation process. In this research, local biomasses such as macadamia shells and coffee bean pulp were used in a fixed-bed downdraft gasification system for producer gas generation. The producer gas was then used as fuel for sample raw meat burning in a double-chambered incinerator prototype. From the experimental results, it was found that at the equivalent ratio of 0.9, the producer gas from both macadamia shells and coffee bean pulp can raise the maximum temperature in the secondary chamber to 750oC, which can eliminate the undesirable smell and pollutants from the combustion process. In addition, by igniting the secondary chamber, the observed light opacity decreased by 83%, compare to the ignition of only the primary chamber.
