Husk Fired Packaged Steam Boilers
ADVANCED BIOMASS COMBUSTION TECHNOLOGY FOR HIGH-EFFICIENCY STEAM GENERATION
BELLFABS BOILERS manufactures a premium range of Husk Fired Packaged Steam Boilers engineered specifically for efficient combustion of rice husk and other lightweight biomass fuels. Designed with a three-pass, fully wet-back configuration, these boilers deliver superior thermal efficiency, reliable steam generation, and optimized fuel utilization.
The boilers are equipped with advanced automatic fuel feeding systems through either:
- Pneumatic Husk Feeding System
- Screw Conveyor Feeding System
These systems ensure continuous and uniform fuel feeding into the furnace, resulting in stable combustion, reduced manual intervention, and improved operational consistency.
Rice husk being a low-density and high-volatile biomass fuel requires specialized combustion engineering. BELLFABS Husk Fired Boilers are therefore designed with:
- Large furnace volume
- Optimized grate arrangement
- Controlled primary and secondary air distribution
- Enhanced combustion residence time
This ensures complete combustion, minimized unburnt particles, and reduced fuel wastage while maintaining stable steam pressure under varying load conditions.
The multi-pass heat recovery arrangement extracts maximum heat from flue gases, reducing stack losses and improving overall boiler efficiency. Manufactured in compliance with IBR standards, BELLFABS boilers are trusted for their durability, fuel economy, and long operational life across demanding industrial applications.
