AN EXPERIMENTAL STUDY OF UPDRAFT BIOMASS GASIFIER USING BIOFUELSC. Sivakandhan, G. Murali and P. Suresh Prabhu
The gasification technology has been facing number of obstacles since its beginning. The relative cost and availability of fossil fuels determine the focus and research in gasification. This study is concentrated on the testing and comparing the composition of syngas produced in a 0.221 m3 fixed bed updraft gasifier from the combustion of coconut shell and biofuel briquette. The firing of the gasifier was done for a period of 8 hours and readings were taken at regular intervals. The composition of the syngas was estimated using Orsat apparatus which uses Potassium Hydroxide for carbon dioxide and Ammoniacal Cuprous Chloride for carbon monoxide. And the composition of CO in syngas produced using coconut shell was 25% that of using briquette it was relatively less. So, coconut shell can be concluded as a most suitable fuel for an updraft gasifier as compared to biofuel briquette.
