Gasification stove, sawdust, wood shavings, water boiling testAbstract
The performance of a forced-draft biomass gasifier stove using sawdust and wood shavings was evaluated through the Water Boiling Test (WBT) at air velocities of 0.7, 0.9, and 1.05 m/s. Increasing airflow improved reactor temperature and gas yield for both fuels, with wood shavings achieving higher temperatures (465.9°C) and gas yield (46.62 wt.%) than sawdust. Wood shavings also produced greater water evaporation and higher thermal efficiency (15.07–19.59%) compared to sawdust (11.83–12.99%). Although fuel consumption increased with airflow, wood shavings demonstrated more stable combustion and better heat transfer due to its higher porosity and improved airflow distribution. These findings show that fuel structure and airflow significantly influence gasifier stove performance.
