SHELL & WATER WALL MEMBRANE PANEL COMBINATION BOILER

COMPACT HIGH-EFFICIENCY STEAM GENERATION SYSTEM WITH INTEGRATED COMBUSTION TECHNOLOGY

BELLFABS BOILERS presents an advanced range of Hybrid Steam Boilers, combining the operational reliability of shell type boilers with the superior heat absorption capability of Water Wall Membrane Panel Furnace Technology. Engineered for compact installation, high thermal performance, and fuel flexibility, these boilers are specially designed for industries requiring efficient steam generation with optimized space utilization and reduced installation complexity.

The boiler incorporates a fully integrated combustion and heat recovery system mounted on a single engineered frame, including:

• Air Pre-Heater
• Air Duct System
• Flue Gas Ducting
• ID Fan & FD Fan Arrangement
• Integrated Furnace & Boiler Assembly

This compact integrated design ensures simplified installation, improved system alignment, and enhanced operational reliability.

The membrane panel furnace is designed to absorb maximum radiant heat directly into water-cooled surfaces, resulting in faster steam generation, improved combustion stability, and efficient heat utilization. The combustion chamber is engineered with optimized furnace volume and controlled air distribution to ensure complete combustion of both manual and automatically fed fuels.

BELLFABS Hybrid Boilers are available with:

• Manual Feeding System.
• Fully Automatic Fuel Feeding System.

depending on fuel type and plant operational requirements.

Designed and manufactured in accordance with Indian Boiler Regulations (IBR), BELLFABS Hybrid Boilers deliver dependable industrial performance, operational flexibility, and long-term durability for continuous process applications.
