FULLY AUTOMATED BIOMASS COMBUSTION SYSTEMS FOR HIGH-EFFICIENCY INDUSTRIAL STEAM GENERATION

BELLFABS BOILERS manufactures a premium range of Shell Type Water Wall Membrane Panel Wood Chips & Briquettes Fired Steam Boilers, engineered for industries seeking highly efficient, fully automated, and sustainable biomass-based steam generation solutions.

Designed with advanced Water Wall Membrane Panel Furnace Technology, these boilers ensure maximum radiant heat absorption, superior combustion stability, and high thermal efficiency while maintaining rugged reliability for continuous industrial operation.

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

• Screw Feeders, and
• Pocket Feeders

This integrated fuel handling arrangement ensures continuous, uniform, and controlled feeding of wood chips and biomass briquettes into the furnace, resulting in stable combustion, optimized fuel consumption, and minimal operator intervention.

The combustion chamber is scientifically engineered with:

• Large furnace volume
• Optimized grate configuration
• Balanced primary and secondary air distribution
• Extended fuel residence time

These features enable complete combustion of biomass fuels with varying density and moisture content while minimizing unburnt losses and clinker formation.

The water wall membrane furnace directly absorbs radiant heat from combustion, significantly improving thermal efficiency and reducing refractory dependency. Combined with a multi-pass heat recovery system, the boiler extracts maximum thermal energy from flue gases, reducing stack losses and lowering overall operating cost.

Manufactured in strict accordance with Indian Boiler Regulations (IBR), BELLFABS boilers are designed to deliver dependable steam generation, superior fuel economy, and long-term industrial durability.
