Dual Firing Wood Semi Industrial Boilers

Dual Firing Wood Semi-Industrial Boilers Flexibility | Power | Sustainable Industrial Heating At IndianBoilers.com, our Dual Firing Series provides the ultimate fuel security for your production line. These semi-industrial boilers are specifically designed to operate primarily on Wood/Biomass, with the secondary capability to fire Gas or Oil. This “Hybrid” approach allows you to take advantage of low-cost timber and wood waste while having a backup fuel source ready at the flip of a switch, ensuring your factory never stops due to fuel shortages. Key Features & Performance True Fuel Flexibility: Seamlessly switch between Firewood/Briquettes and Gas/Diesel depending on price and availability. Hybrid Furnace Design: Features a large-volume primary furnace for efficient wood combustion and a secondary combustion chamber optimized for high-efficiency burners. High Thermal Efficiency: Designed with a 3-pass heat exchanger that achieves 75%–80% efficiency on wood and up to 88% on gas/oil. Rugged Grate System: Equipped with heavy-duty cast-iron fire bars designed to handle the high temperatures of wood-fire without warping. Large Fire Door: Extra-wide feeding door to accommodate larger logs, reducing the labor required for fuel preparation. Low Carbon Footprint: Utilizing wood as a primary fuel makes your steam generation carbon-neutral while maintaining industrial-scale output. Operating Range Capacity: 100 Kg/hr to 500 Kg/hr Fuel: Coal, Wood, Gas, Oil, or Electrical Power Pressure: 7.00 Kg/cm2 Core Industry Applications These dual-fired boilers are the backbone of industries with access to wood waste: Plywood & Furniture: Utilizing internal wood waste to power steam presses. Food Processing: Reliable steam for boiling, drying, and pasteurization using agricultural waste. Textile Dyeing: High-volume steam requirements met with low-cost biomass fuel. Chemical Plants: Consistent heat for reactors with a gas-fired backup for precision control. Agro-Industries: Utilizing husks, shells, and wood for drying operations. Advantages Safety Interlocks: Equipped with water level controllers, pressure switches, and safety valves that work across both firing modes. Simplified Conversion: Our dual-firing units come with a pre-installed burner mounting plate, making the transition from wood to gas/oil fast and easy. Advanced Pollution Control: Can be integrated with Cyclones or Multi-Cyclone Dust Collectors to ensure clean stack emissions that meet local PCB norms. Ahmedabad Heritage: Robustly manufactured to handle the tough operating conditions of the Indian industrial landscape.

Frequently Asked Questions How long does it take to switch from wood to gas? Once the wood fire is extinguished and the grate is cleared, the burner can be activated in roughly 15–20 minutes. Can I use sawdust or wood chips? Yes, though these fuels burn better with our specialized forced-draft (FD) fan systems to ensure complete combustion. Is the maintenance higher for dual-firing boilers? While wood firing requires periodic ash removal, the overall maintenance is low due to our high-quality refractory and heavy-duty shell design. Does this require a tall chimney? Yes, wood-firing requires a natural or induced draft, usually necessitating a chimney of 20–30 meters depending on capacity. Are these boilers IBR certified? We manufacture both IBR and Non-IBR versions depending on your steam capacity and local regulatory requirements.
