SCOPE OF SUPPLY
HUSK GEN MODEL FBC FIRED BOILERS
CONSTRUCTION :
The Fluidised Bed Boilers offered by us are made as per the latest IBR
Regulations and are of Class-I Fusion welded construction. Stringent
quality control is observed at every stage of manufacture right from raw
material stage to testing of Boiler prior to dispatch. The pressure parts
are manufactured from Boiler Quality Steel, fully welded construction,
shell radiograph and hydraulically tested.
One Steam Cum Water drum which incorporates the Smoke Tube boiler
bank.Water tubes are provided within the combustion area to maintain a
furnace temperature range of 6500C to 7500C. These tubes are connected
with header at the bottom along with downcomers to form a natural water
circulation circuit.
A convective evaporator section consisting of a Smoke tube boiler section
is so designed as an inline arrangement.
FLUE GAS PATHS :
The Boiler consists of a configuration enabling high turn down ratios. The
combustion once completed in the bed is released into the free board
zone at a temperature slightly higher than 750oC. The Water Tubes
absorb the heat before leading the gases into the super heater zone and
then to Smoke tube boiler section (Convection Bank). The flue gases are
then taken into an APH, Dust Collector, I.D.Fan and into the chimney.
STEAM CUM WATER DRUM
The boiler consist of one Steam cum water drum. This drum connects the
Risers and Downcomers to various Heating Surface Sections within the
Boiler. Feed Water is fed from the Feed Pumps into this drum. Water level
is maintained in the drum thru Mobrey control provided.This drum also
contains the Convection Bank of Tubes.The Drum is provided with Hinged
doors at the Rear for easy approach and Cleaning. A Blowdown
connection is provided to remove the sludge during operation.

CONTROL PANEL :
The panel consist of a sophisticated but user friendly circuit enabling the
operator to run the boiler in automatic or manual mode as desired.
Various instruments and safety features are as detailed
below:
In auto mode the boiler will operate all sequences
automatically. The boiler can be also adjusted to start
and stop automatically within a pressure range of 3 to 5
Kg/cm2. However in case of Low Loads, below 75% of
MCR, steam superheat temperature will differ from
Designed Values.Initially during pre fluidisation state the
boiler needs to be started manually.

MICRO PROCESSOR BASED FUEL FEEDING :
Microprocessor based indicator cum controller(s) is provided
for Fuel Feeding. The controller senses the temperature of
fluidisation and delivers a precise signal to the dynodrive(s)
to increase / decrease the fuel feeding rate. By the use of
this advanced micro processor technology precise control of
feel feeding is maintained leading to Low excess air losses
and subsequently a very high fuel efficiency.

CASTINGS
The Castings are made out of robust alloy steel of Radiography quality.
The casing is split horizontally at the center line, permitting easy access to
the interior for inspection without disturbing the steam inlet and outlet
lines. Centre line support ensures precise alignment of the turbine with
driven machine.
WHEEL

tolerances, and located between heavy duty Bearings for continuous and
long operations. The Built-up Rotor is dynamically balanced to a high
degree of accuracy to ensure vibration free, smooth, and years of trouble
free operation of the Turbine.
SHAFT
The shaft is made out of Forged Carbon Steel & the Section under the
Carbon glands is chrome plated to minimize erosion & corrosion.
NOZZLES
Nozzles are made of S.S. and manufactured with High accuracy as per
the specified Steam parameters for developing optimum efficiency.
BLADES
These are manufactured out of a thick section of erosion and corrosion
resistance stainless steel and fitted firmly in the rim of the wheel. A
sectional shroud ensures added rigidity. These blades are renewable and
replaceable, if need arises, on account of changing operating conditions.
BEARINGS
Precision split sleeve journal bearings incorporate Babbitt lining, and are
forced lubricated.
GLANDS
The glands are of carbon ring type, each composed of three segments
held together by an inconel spring that incorporates anti-rotation stops.
Carbon rings require no lubrication.

to preclude any thick impurities into entering.
OVERSPEED TRIP GOVERNOR
IBL BT-4 Turbines include an Overspeed Governor. It consists of a Ring
carried on the Turbine Shaft and operates the Emergency Valve when the
Turbine speed reaches a preset speed at 10% above the normal running
speed of the rotor.
HAND NOZZLE VALVE
One Hand operated nozzle control valve is provided to maintain
reasonable high efficiency on part load operation.
LUBRICATION
Forced lubrication is provide by a geared type oil pump which is fitted on
to the reduction Gear Box. The capacity of the pump is 90 LPM. A full duty
motor driven Oil pump is standard to flood the Bearings during start up
and shut down of the Turbine.
GEAR BOX
This non-integrated unit is housed separately and coupled with the
Turbine with metaflex type coupling. The advantage is smooth and long
life performance. This coupling with thin stainless steel flexible
Membranes gives better performance. The Gear box is a single helical
type speed reduction unit as per AGMA standard.
