Experimental Investigation on Fluidized Bed Gasifier Using Saw Dust as Biomass
Abstract Today, the world is in an urge for search of alternative fuels to replace fossil fuels because of their increasing prices and environmental problems. With the rise in the cost of fossil fuels and concern over the environmental impact of our increasing energy consumption, energy from biomass is increasingly recognized as the anchor for a strong future in renewable energy production. Biomass is a renewable and sustainable source of energy. It covers wide range of materials such as plants, agricultural residues, animal wastes. Biomass is derived from recently living organisms and plants unlike fossil fuels which have taken millions of years to achieve this current form. Gasification is a thermochemical process which can be used to convert solid fuels into more standard and usable form than original biomass. Gasification products include hydrogen, carbon monoxide, carbon dioxide, methane, tar, and dust. Gasification yield is influenced by gasification media and the operating parameters. In the present work, air and air–steam gasification of sawdust are carried out in a bubbling fluidized bed gasifier to investigate the gaseous product and thereby studying the influence of gasification agent and the operating parameters like temperature, steam to biomass ratio (SBR), and equivalence ratio (ER). In the experimental study, it was observed that in air–steam gasification maximum hydrogen yield was 8.64% at a temperature of 700 °C, ER = 0.32 and SBR = 0.66. Maximum hydrogen yield was found to be 8.4% for air gasification at a temperature, T = 760 °C and ER = 0.3.
