HIGH-CAPACITY WATER TUBE BOILERS FOR CONTINUOUS INDUSTRIAL STEAM GENERATION

ADVANCED WATER TUBE TECHNOLOGY FOR HIGH PRESSURE & HIGH EFFICIENCY OPERATION

BELLFABS BOILERS manufactures a premium range of Bi-Drum Water Tube Steam Boilers engineered for high-capacity, high-pressure, and continuous industrial steam generation applications. Designed with advanced water tube technology, these boilers deliver superior thermal efficiency, rapid steam generation, and exceptional operational reliability under demanding process conditions.

The boiler consists of:

• Steam Drum (Upper Drum)
• Mud Drum (Lower Drum)

interconnected through precisely engineered water tube circuits that enable efficient water circulation and rapid heat transfer. The furnace is integrated with Water Wall Membrane Panel Construction, ensuring maximum radiant heat absorption and optimized combustion performance.

BELLFABS Bi-Drum Boilers are designed to efficiently utilize a wide range of fuels including:

• Coal
• Biomass
• Rice Husk
• Wood Chips
• Briquettes
• Bagasse
• Agro Waste
• Oil & Gas Fuels

depending on the combustion system configuration.

The combustion chamber is scientifically engineered with optimized furnace geometry, controlled air distribution, and advanced heat recovery systems to achieve:

• Complete combustion
• High thermal efficiency
• Reduced fuel consumption
• Stable steam pressure
• Lower emissions

The water tube arrangement allows faster steam generation and superior load handling capability compared to conventional boiler systems, making Bi-Drum Boilers ideal for large process industries and continuous operation plants.

Manufactured in strict compliance with Indian Boiler Regulations (IBR) and international engineering standards, BELLFABS Bi-Drum Boilers are built for rugged industrial performance, long service life, and dependable steam generation.
