ADVANCED COMBUSTION TECHNOLOGY FOR HIGH-EFFICIENCY MULTI-FUEL STEAM GENERATION

BELLFABS BOILERS offers a technologically advanced range of Shell Type Water Wall Membrane Panel Fluidized Bed Combustion (FBC) Steam Boilers, engineered for high combustion efficiency, fuel flexibility, and reliable continuous steam generation for demanding industrial applications.

Designed with advanced Fluidized Bed Combustion Technology, these boilers are capable of efficiently firing a wide range of solid fuels including:

• Coal
• Saw Dust
• Rice husk

The boiler is equipped with a 100% automated fuel feeding system utilizing:

• Screw Feeders
• Pocket Feeders

This ensures continuous, controlled, and uniform fuel feeding into the fluidized combustion bed, resulting in stable furnace temperature, improved combustion efficiency, and consistent steam generation with minimal operator intervention.

The combustion chamber is integrated with Water Wall Membrane Panels, enabling direct radiant heat absorption and significantly improving thermal efficiency while reducing refractory heat losses. The fluidized bed maintains intense turbulence and excellent mixing of fuel and air, ensuring:

• Complete combustion
• High heat transfer rates
• Reduced unburnt losses
• Uniform temperature distribution
• Lower emissions compared to conventional firing systems

The multi-pass heat recovery system further extracts maximum thermal energy from flue gases, reducing stack losses and improving overall boiler performance.

Manufactured in compliance with Indian Boiler Regulations (IBR), BELLFABS FBC Boilers are designed for rugged industrial operation, superior fuel adaptability, and long-term reliability.
