Biomass gasifier

Biomass gasification is a process of converting biomass to a combustible gas in a reactor vessel, 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 has a calorific value of 4.5 - 5.0 MJ/cubic metre. It has to be cooled and cleaned before using in internal combustion engines for power generation purposes.
Biomass fuel
A wide range of woody biomass in the form of wood or agro residue can be used in the gasifier. In general any biomass that has a density of more than 250 kgs per cubic meter can be used for gasification. Biomass from trees of Eucalyptus, Casuarina, Acacia, Albizzias, Cassia siamea and many other species and agricultural residues such as coconut shell, husk, fronds, corn cobs, corn stalks, mulberry stalks, briquettes of biomass or saw dust, coffee husk, groundnut husk, rice husk etc. can be used as fuel in fuel specific gasifiers.
Conversion efficiency
High Conversion efficiency from solid Biomass to gaseous fuel of upto 85% in hot gas mode, 75% in cold gas mode and 65% with rice husk is possible. Each Kg of biomass can producer 2.5 to 3.0 cubic meters of gas having a average calorific value of 4.5 - 5.0 MJ/cubic metre. During power generation through gen set upto 85% diesel saving is possible in duel fuel mode.
