Indirect Use Hot Air Generator

Indirect Hot Air Generator consists of a Fluidised Bed Combustion Furnace, Radiative Heat Exchanger, Convective Heat Exchanger, Heat Recovery Unit, Air pollution control equipment as well as Invertor controlled fans.

Radiative heat exchanger:

Radiative Heat Exchanger comprises of a bank of S.S. Pipes, welded with a free floating Box Header, which rested on rollers, supported on a channel frame.

Convective heat exchanger:

Convective Heat Exchanger comprises of a bank of S.S./M.S Pipes, welded with a free floating Box Header rested on rollers, supported on a channel frame. These heat exchangers are in two stages, for increasing the overall system efficiency.

Heat recovery unit [HRU]:

It recovers heat from the flue gases, and in turn heats the incoming clean atmospheric air by cross flow design.

Pollution control equipment:

High efficiency Cyclone is provided for collecting fine ash from flue gases emitted in the ambient through the stack.

FBC Furnace with wind box:

Groundnut shell / Coal / Lignite fired FBC system comprises of a Nozzle plate with attached Air Plenum and a side structure frame bolted with Nozzle plate . Graded CI (Cast iron) nozzles are fitted on top of the nozzle plate. Sand drain pockets are provided for removal of heavy unwanted silica particles from the FBC Furnace.


Refractory material:
All the standard / specially shaped refractory bricks for the furnace walls along with fixtures and holders are provided.
