BI DRUM FBC BOILERS

Bi Drum Boiler is generally used to generate high Pressure steam required for incidental power generation or cogeneration. It is also used for saturated steam applications which demand uninterrupted operation on highly choking fuels. This boiler is very rugged and can operate continuously throughout the year.
Bi Drum Water tube steam boiler design, which is highly acclaimed all over the world for its reliability of performance and sturdiness
Water wall is provided with 2 ½’’ size tubes and are spaced 1’’ apart. This provides larger volume of water in furnace walls and contributes to faster load Response.
Soot Blowers are properly located for effective convective cleaning
Economizer and Air Pre-Heater are provided for better waste Heat recovery and to increase the overall thermal efficiency of boiler.
Capacity Ranging from 5tph to 15tph and pressure ranging 10.54kg to 45Kg/Cm2
Capable of firing coal dust, lignite, rice husk, saw dust, dolochar etc

WASTE HEAT RECOVERY BOILER

Waste Heat Recovery Boilers (WHRB) are fully packaged smoke tube industrial boilers with advanced instrumentation to deliver maximum possible heat recovery
These Boilers are ideal to recover heat from gen sets, incinerators, furnace and kiln exhausts
Can support fluctuating steam requirements
Reduced capital cost requirements and overall system operating cost
Provides increased protection of the environment and aids in conservation of natural resources

PROCESS AND POWER BOILER ACCESSORIES

Super Heater:

Super Heater is a heat exchanger which convers saturated steam into super-heated steam. It’s constructed in two halves – radiation and convective zones connected to each other by an attemperator. The convective zone of the super heater is shielded from radiation by nose wall, which also guides the flue gas co cover the entire convective super heater area

Economizers

Economizers are made of bare tubes aids in heat recovery and improving efficiency of the boiler. It uses the heat of the flue gases coming out from the boiler to pre heat the water that goes to the boiler shell. In smaller boilers it’s not pressurised and in high-capacity boilers it is pressurised.

Air Pre-Heater:

Air Pre-Heater is also a heat recovery equipment situated last in the flue gas path. It is a cross flow gas to gas heat exchanger which provides hot air for combustion.

In Bed Coils

In Bed Coils is a part of FBC boiler where the heat exchanger is immersed in a bubbling send bed, to help take away the heat from the bed. This helps in maintaining combustor temp below the ash melting point using minimal excess air which also results in higher efficiency. Since send is continuously rubbing against the in bed tubes special studding is provided on in bed coils.

Deaerator

Deaerater is a device that is widely used for removal of oxygen and other dissolved gases from the feed water. The presence of dissolved oxygen causes rapid localized corrosion in boiler tubes

Feed water is sprayed in thin films into a steam atmosphere allowing it to quickly heated to saturation. Spraying feed water in thin films increases the surface area of liquid in contact with the steam, which results in more rapid oxygen removal and lower gas concentrations. This process reduces the solubility of all dissolved gases and removes them from the feed water. The liberated gases are then vented out from deaerator
