This study investigates the tar content in an updraft gasifier modified with three gas outlet channels, namely the upper channel, the reduction channel, and the combustion channel, using coconut shell biomass as the feedstock. The research is motivated by the large potential of biomass resources in Indonesia and the main drawback of updraft gasifiers, namely the high tar content, which can disr…
This study aims to analyze the stability of coconut-shell biomass gasification in a modified updraft gasifier equipped with two gas outlets: a reduction zone outlet and a combustion zone outlet. The modification was implemented to evaluate operational characteristics, combustible gas stability, flame behavior, and performance differences between the two outlets. The reduction zone produced CO, …
The increasing dependence on fossil fuels poses challenges to energy security, highlighting the need for renewable energy alternatives such as biomass. Coconut shell, a carbon-rich biomass waste, has significant potential to be converted into combustible gas through gasification. Although updraft gasifiers offer high efficiency, they are prone to excessive tar production, which can be mitigated…
