Abstract: The world is facing serious environmental problems due to the green house gas emissions from the use of fossil fuels. Renewable energies like biomass fuels can play an important role in reducing green house emissions and other pollution. A research study was carried out to pre-treat sugarcane bagasse through torrefaction process for generating a non-cohesive powdery bagasse and to fabricate a cyclone gasifier for gasification of sugarcane bagasse. A 1D1.5D nomenclature of the cyclone was selected for fabrication of a cyclone gasifier. The cyclone having a barrel of 150 mm diameter, cone of top and bottom diameter are 150 and 75 mm respectively, tangential inlet duct of rectangular cross-section (38x75 mm), cleaned gas outlet of 93.7 mm diameter, dust outlet of 78 mm diameter and 50 mm in length was developed. The biomass feeding rate was kept as 40 kg/h for the selected particle size range of 0.18-0.70 mm. The heating value of the producer gas at an equivalence ratio of 1:4 was about 5.0 MJ/Nm3. The present study concludes that the torrefaction of biomass improves grindability, proximate composition by increasing the carbon content with a decrease in moisture and oxygen content, and biochemical composition by decomposition of hemicelluloses and softening of lignin. As per cyclone separator design standards, the coarse and fine particles in the size ranges of 0.35-1.40 mm and 0.18-0.70 mm can be best separated and gasified in a cyclone separator of 1D2D and 1D1.5D nomenclature respectively.
