Abstract

Biomass gasification is the most appropriate natural energy conversion technology for clean coal mechanism and pollution control purpose. Due to the decreasing conventional and non-renewable resources as fossil fuels and their environment impaction, biomass becomes the more important CO2-nuetral fuels. In this work, CFD modeling and simulation is used for performance analysis of a 10kWe downdraft fixed bed type biomass gasifier which is installed at Department of Energy And Environment Mgt. in UTD Rajiv Gandhi Proudyogiki Vishwavidyalaya, Bhopal. The complete model is created in ANSYS MESHING and simulated in ANSYS FLUENT. The simulation work is done through the species transportation model with volumetric and particle surface reaction for calculation of gas temperature and mass fractions. In this study work on thermal, kinematic and chemical reaction analysis of gasifier view modeling and simulation on fluent.

Keywords: Biomass, downdraft-gasifier, CFD simulation, ANSYS FLUENT, air velocity, species transportation model
