Biomass gasification is a process of converting biomass to a combustible gas in a reactor, known as gasifier, under controlled conditions. The combustible gas, known as producer gas has a composition of approx. 19 % CO, 10 % CO2, 50% N2, 18% H2 and 3 % CH4.This gas which has a calorific value of 4.5 - 5.0 MJ/cubic metre is then cooled and cleaned prior to combustion in internal combustion engines for power generation purposes.
Biomass for gasifier:
A wide range of biomass in the form of wood or agro residue can be used in the gasifier:Any biomass that has a density of more than 250 kgs per cubic meter can be used for gasification.
Woody Biomass from trees of Eucalyptus, Casuarina, Acacias, Albizzias, Cassia siamea and many other species
Agricultural residues- Coconut shell,husk ,fronds,corn cobs,corn stalks,mulberry stalks, briquetted biomass of saw dust, coffee husk, groundnut husk, rice husk etc
