Biomass Gasifier System
Introduction
Gasifier Action Research Project RP01066 at Chemical Engineering
Department of IIT Delhi has developed village level gasifier
system of 5, 10 and 20 HP based on partially pyrolysed biomass
fuels. Gasifier systems convert biomass into producer gas,
which is then intoroduced into diesel engines. Injection of
the gas results in reduction of diesel consumption in engines
by 65 to 75%. These systems have been effectively utilized
for rural electrification using locally available agro-forestry
residues. The gas can also be used for thermal applications
in furnaces, stoves, heaters etc. Biomass material is partially
pyrolysed (carbonized) in the drum charring unit. It is sized
and fed to the gasifier where heating is initiated using the
hand blower. The producer gas is cooled and cleaned in the
hydro-separator before it enters the surge tank. The gas is
then either burnt directly or fed to the engine-pump / alternator
set as per requirement. Biomass Fuel As biomass fuel, many
type of local agro-forestry residues having ash content less
than 4-5 percent on dry basis. Corn Cobs - Lantana Camara
Weeds - Arhar Dal Stalk - Twigs of Bushy Plants and Trees
- Bhimal & others can be used.
Special Features:
Simplicity of construction, easy maintenance - all internal
parts easily approachable and replaceable, No moving parts
except the engine, Low cost due to mild steel construction
except 3-4 air inlet tubes of stainless steel, Quick start
up within 15 minutes after feed charging, Simple and reliable
operation - one day training, Charring route - tar free -
no choking of engine, Provision of smokeless fuel as additional
output
Prospective Users:
Industries for electrical and thermal applications.
