These boilers are suitable for burning
of either individual or in combination the fuels like coal,
oil, gas, rice husk, bagasse, biomass and other agricultural
Coal firing units may require continuous ash discharge traveling
grate, where ash percentage is high. The coal with small ash
percentage and other solid fuels are successfully burnt on
Conservative rates of heat release, both
for combustion chamber and grate are selected for all fuels.
Grate dimensioning of furnace and arrangement of further heating
surfaces such as super heater, convention bank, economizer
and air heater run minimum risk of clogging, even in case
of over loading. The soot blowers, retractable and rotary
provided are sufficient to keep the surface clean for longer
period which is a requirement for boilers for co-generation.
Box type combustion chamber uniform gas
velocity. The bank tubes are evenly placed, as a result, gases
leave the furnace at fairly uniform temperature. With the
Uniform evaporation across section.
Uniform water level in the drum
Uniform expansion of pressure parts is achieved. These
features result in quick response to rapid load swing, carry
high rating and produce dry steam at all
For reducing superheater tube metal temperature,
the heating surface is divided in two section with counter
flow and parallel flow arrangements. The attemperator, to
control the steam temperature is, placed in interstage or
at the outlet, depending on the final steam temperature requirement.
Large Air Heaters are provided for higher
heat recovery and therefore higher efficiency. The hot air
assist combustion and makes furnace condition more suitable.
FIRE AIR SYSTEM
To reduce smoke and fly ash, over fire
air system is used. Over fire air burns vaporized volatile
matter which is in high percentage in Bagasse.
These are offered where improvement in
efficiency and operational ease is important, particularly
for large size boilers.
Spreaders strokers for coal are mechanical,
where as for bagasse and similar fuels are pneumatic. These
are designed for suspension burning of lighter particles and
uniform distribution of fuel on the grate. Location of spreaders
are so decided that with minimum carry over of lighter particles

OFFER FOLLOWING BOILER TYPES
Multi-fuel Boilers upto 150 T.
Pressures upto 110 ATA.
Super heater temperature upto 515ºC.
Pre-engineered shop assembled package boilers.
Drum internals consist of chevron driers
Andhorizontal Steam Separators. These internals are prefabricated
and bolted welded in the steam drum. Best performance is assured
over wide variation on of load. These work well during sudden
change in the load with normal boiler water conditions high
standard of steam purity is maintained.
