Design and Fabrication of Biomass Gasifier

Abstract

       Today’s Energy Hungry World is consuming non-renewable sources of energy such as fossil fuels at alarming rates, which has increased the importance of developing renewable energy sources. Biomass is one such source of renewable energy which is abundantly available in India in the form of industrial and agricultural by-products. In this project we aim to contribute in a small way to this changing face of sustainable energy resources by designing and fabricating a Downdraft gasifier using two sources of biomass viz. rice husk and wood pellets. The syn-gas subsequently produced are used to run an I.C. Engine and a performance analysis would be conducted. High heat transfer rates of the walls and tubes may allow the particles of biomass to achieve a high enough temperature necessary for Substantial tar destruction and complete gasification of greater than 90 per cent of the biomass particles into reaction products including hydrogen and carbon monoxide gas in a very short residence time between a range of 0.01 and 5 seconds.
