Background
INDCON
have been pioneers in boiler design & manufacturing in northern
India. With our outstanding track record of innovative products, we
are responsive to the latest combustion and heat transfer engineering
and developments translating all this knowledge into fuel efficient
steam boilers.
Construction
INDCON
boilers are of class-1 welded construction and designed in accordance
with IBR or any other international code. Strict quality control is
maintained at all production stages expert shop supervision is
provided to ensure finest workmanship. All welding seams are 100%
radiographed to ensure durability and longer life. Hinged doors are
provided at front and rear at the ends of the boiler to give easy
access for inspection, cleaning and replacement of tubes.
The Mechanism
The
fuel is added to a bed of non-combustible particles like sand and is
kept in constant movement by combustion air which is blown through
from below. The mixed bed behaves as if it were a boiling liquid. It
is compact fluidised. The normal operating temperature of fluid bed
is 750 Deg.C. and at this low temperature the ash is not sintered or
melted. The larger area of contact between fuel and oxygen of
combustion air and good mixing gives intensive combustion. The larger
quantity of heat held by the bed function as a thermal reservoir and
levels out the variation in fuel quantity and moisture content. The
fuel particles automatically remain suspended for longer period of
time and swirl around in hot material of fluid bed until they burn
out completely to ash.
