CFD MODELING OF BIOMASS REACTOR

Abstract

Biomass gasifier is a device that converts solid biomass (ex. Wood, agro residues like wheat straw, mustered straw etc) into a combustible gas called as producer gas. The composition of product gas determines its quality as a fuel. High concentrations of combustible gasses such as carbon monoxide, hydrogen and methane increase the combustion energy of the product gas. India being agriculture based country that produces tonnes and tonnes of agriculture residue that can be utilized for to meet the rural energy demand which also contributes to environment protection. This study focuses in understanding the processes taking place in the biomass reactor also to investigate and model these reactions by considering a 100 kg/hr down draft biomass (wood) gasifier. The aim of the present work is to predict the performance of the down draft biomass gasifier through computer simulation with computational fluid dynamics (CFD) software. The computation is then extended to study the var...
