Influence of CO₂ injection on biomass updraft gasification process

Abstract

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat. The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming. This study focuses on to performance analysis of updraft gasifier with the injection of CO2 as gasifying agent. During the study CO2 was fed in to updraft gasifier in different feed ratios and producer gas composition was analyzed. Rubber wood chips were used as the feed stock of gasifier and testings were carried out in input fractions of CO2 to analyze its impact of CO yield.
