The biomass gasifier based power generation system has a
fixed bed down draft reactor, a heat exchanger for hot air
generation and a series of gas cleaning and cooling equipment.
The reactor was designed with multilayer insulation, to
reduce the heat loss and to maintain high temperature. Hot air
was injected into the gasification reactor through twelve
nozzles, distributed equally at two tiers. Six nozzles were
provided in each tier.
A vibrating grate, ash removal system was introduced to
remove the ash from the reactor, at a regular interval. The
vibrating grate was designed in such a way, that it removes
only the ash from the reactor while retaining the charcoal in
