ICAR-CIAE Biomass based Power Generation System
The production capacity of the power plant is 25kW. The plant is run by biomass briquettes and other available biomass. Fuel consumption ranges between 1.1-1.2 kg/kW. The plant is equipped with a downdraft gasifier, a rotating grate, ventury type suction unit which sucks the gas as well as cleans it from tar. The system is also equipped with three stages of cleaning consisting of wood blocks, saw dust and charcoal dust for further cleaning of tars.
ICAR-CIAE Biomass Briquette based Rapid Combustion System for Thermal Application
A force draft rapid combustion system for thermal applications using briquettes as a fuel source comprising a combustion chamber insulated with ceramic fibre blanket, continuous biomass feeding unit with provision for feed control, raiser at the top of the combustion chamber, axial fan for air supply, cladding for thermal safety, and sliding ash bin for easy ash has been developed. The biomass feeding unit and axial fan is operated using a 12V, 7Ah battery.
ICAR-CIAE Pyrolysis System for Bio-oil Production from Biomass
A fluidized bed reactor has been developed for 20 kg/h capacity of biomass for fast pyrolysis that comprises mainly reactor unit, cyclone, quencher, recycling unit and feeding unit. Heating coil is wrapped on the outer periphery of main reactor to raise the temperature of bed material up to 600°C and the temperature is controlled with the help of a microcontroller. A screw type feeding system has been provided to feed ground biomass inside the reactor and feed rate is controlled by varying speed by using variable frequency drives. A regenerative blower has been used to fluidize the bed of alumina and biomass inside the reactor, and nitrogen gas is used for initial fluidization of bed materials followed by subsequent fluidization using non-condensable pyrolysis vapour.
Pilot Plant for Bio-Char Production
This is a pilot plant of 300 kg loading capacity at a time. The reactor unit is indirectly heated by firing biomass. A blower is needed for burning of biomass. The outer furnace unit is made of fire bricks. Temperature can reach up to 350°C. Recovery is about 33%. Cost is 2-2.5 lakh.
