Effectiveness Study on The Vacuum Biomass Gasification System Using Variation of Suction Pump Rotation Power and Biomass Wetness

Abstract

Environmental damage and depletion of fossil fuels trigger the development of biomass conversion technology to produce environmentally friendly fuels. One of them, biomass conversion technology is vacuum pressure biomass gasification technology. Previous research has succeeded in converting biomass energy into electricity, but the results are still not effective. In this regard, the effectiveness of the gasification system needs to be improved in this research. The combination of dry biomass and soaked biomass, as well as the combination of suction pump rotation at 1400 and - 2800 rpm, is the focus of this study. Based on the experimental results, the larger the motor rotation, the higher the vacuum pressure. The soaked biomass is more stable in maintaining the level of the amount of biomass in the reactor and the reactor is never overflowing. The combination of 2800 rpm rotation with drenched biomass can maintain the reactor temperature maintained at 800-1000 °C, the most stable and highest evaporation rate is around 23.0 x 10-4 kg/s, and produces the highest heat rate of 5.19 kilowatts. Based on this, the combination of soaking biomass with a rotation of 2800 rpm produces the best effectiveness.
