ADVANCED BIOMASS COMBUSTION TECHNOLOGY FOR HIGH-EFFICIENCY STEAM GENERATION

BELLFABS BOILERS offers a technologically advanced range of Shell Type Water Wall Membrane Panel Husk Fired Steam Boilers, engineered for reliable and energy-efficient steam generation using rice husk and biomass husk fuels. Designed for continuous industrial operation, these boilers combine the ruggedness of shell type construction with high-performance water wall membrane furnace technology to deliver superior combustion efficiency and long operational life.

The boiler is equipped with an automatic screw feeder fuel feeding system, ensuring continuous and controlled feeding of husk into the furnace for stable combustion and uninterrupted steam generation. The combustion chamber is fully integrated with water wall membrane panels, allowing direct absorption of radiant heat and significantly improving thermal efficiency while minimizing heat loss.

Rice husk being a lightweight and high-ash biomass fuel requires specialized furnace engineering. BELLFABS boilers are therefore designed with:

• Large furnace volume
• Optimized grate arrangement
• Controlled primary & secondary air distribution
• Extended combustion residence time

These design features ensure complete combustion, reduced unburnt losses, minimized clinker formation, and improved fuel utilization.

The multi-pass heat recovery system extracts maximum thermal energy from flue gases, reducing stack temperature losses and enhancing overall boiler performance. The membrane wall construction also reduces refractory dependency, resulting in lower maintenance and improved furnace durability.

Manufactured in compliance with Indian Boiler Regulations (IBR), BELLFABS Husk Fired Water Wall Boilers are trusted for their reliability, fuel efficiency, and superior operational performance in demanding industrial environments.
