Bio mass was the fuel used for combustion and produce thermal energy. Gasification was a thermo chemical process it convert solid fuel into gaseous fuel. Gasification is the operation used to produce the combustible gas by burning solid biomass, that combustible gas is also named as producer gas. We are using downdraft gasifier to generate producer gas, why because the down draft gasifier produce a lesser amount of tar content and minimum pressure drop. In our country, large amount of solid waste like coconut shell, groundnut shell, carpentry wastage, bagasse this kind of waste is easily combustible biomass. So we can use that combustible waste to run the down draft gasifier to produce the producer gas. We have fabricated the down draft gasifier with 3.5kW power generation. Performance of gasifier has been analysed in-terms of different zone temperatures and pressure drop, wood consumption this things would be experimentally investigated.
