| Summary: | Gasification is an endothermic reaction process to convert biomass
producing combustible gas called syngas. Gasification is done in a high
temperature with limited oxygen. Biomass has high volatile matter, low carbon
content, and moderate calorific value. Biomass which is used in this study are rice
husk and sawdust. This study was done to determine the time of burning, fuel
consumption rate, gasification process rate, the burning rate, power output and
efficiency.
his study T used gasification stove as a model, refers to an existing design
by adding hopper at the top of the gasifier as a place to supply biomass during the
stove operation. Research was done by testing the stove to boil water (Water
Boiling Test). The volume of water was 1.5 L, the amount of biomass fuel was 0.5
kg. Variation of air velocity was 2 m/s, 2.5 m/s, 3 m/s, 3.5 m/s, 4 m/s and 4.5 m/s.
Variations addition of biomass feed was 75 gr, 100 gr and 125 gr. Observations
were done until the biomass in the gasifier didn�t produce syngas anymore.
esults show R s that the best efficiency of the stove with fuel gasification of
rice husk is 17.24%. The air velocity of the best efficiency is 3.0 m/s and the
addition of feed is 125 gr. While the best efficiency of gasification stove using
sawdust fuel is 11.52%. The air velocity of the best efficiency is 2.5 m/s and the
addition of feed is 125 gr. The increase of air velocity increases fuel consumption
from 0.09 to 0.33 m/hr. The variations of feeding fuel stoves increases the
operational time of 17% - 32%. |
