Abstract

Abstract: Amongst the entirely available renewable energy sources, biomass is measured as the maximum accessible source. It has been estimated that half of the renewable energy can be accessed in terms of biomass. Thermochemical conversion in form of gasification is one of the best ways of converting biomass energy into producer gas. Producer gas produced after the gasification of biomass feedstock is suitable for application as fuels for generating heat, electricity production, internal combustion engines etc. and even for small scale application like heating, refrigeration. Downdraft gasifiers with the easy design, fabrication, low tar production and easily controllable operations are the most suitable gasifiers for small scale applications of gasification process with different end applications. Various researchers are continuously aiming their research to enhance the performance of downdraft gasification. The aim of this paper is to review their work concentrating the downdraft gasification process, kinetics, modelling and pilot scale gasification systems using downdraft gasifiers. The review results observed that the enhancement of technology now should be concentrated for the end application in rural areas.
