HIGH-EFFICIENCY WATER WALL COMBUSTION TECHNOLOGY FOR HEAVY-DUTY INDUSTRIAL STEAM GENERATION

BELLFABS BOILERS presents a premium range of Shell Type Water Wall Membrane Panel Steam Boilers engineered for efficient and reliable steam generation using fire wood as fuel. Designed for industries requiring continuous operation with economical solid fuel firing, these boilers combine the strength of conventional shell construction with advanced water wall membrane furnace technology for superior thermal performance.

The furnace is designed for manual fire wood feeding, allowing operational flexibility while ensuring efficient combustion of varying wood sizes and moisture content. The combustion chamber is fully integrated with water wall membrane panels, enabling direct radiant heat absorption and significantly improving heat transfer efficiency.

Unlike conventional refractory-lined furnaces, the membrane water wall construction minimizes heat loss, reduces refractory maintenance, and enhances furnace durability under high-temperature operation. The optimized furnace geometry and controlled air distribution system ensure:

• Complete combustion of fuel
• Stable furnace temperature
• Reduced unburnt losses
• Improved fuel economy
• Consistent steam generation under varying load conditions

Manufactured in accordance with Indian Boiler Regulations (IBR), BELLFABS Water Wall Membrane Panel Boilers are built for rugged industrial service, long operational life, and dependable performance in demanding process industries.
