Wood Chip Fired Boiler
High-Efficiency Biomass Steam | Automated, Sustainable & Scalable
At IndianBoilers.com, our Wood Chip Fired Boilers represent the next generation of biomass heating. While traditional firewood boilers require heavy manual labor, our wood chip systems are designed for fully automated operation. By using chipped wood waste, we achieve a high surface-area-to-volume ratio, resulting in near-instant combustion and precise pressure control.
Manufactured in Ahmedabad, these boilers are the ideal solution for factories looking to transition away from expensive fossil fuels without sacrificing the convenience of an automated steam plant.
Key Features & Performance
- Fully Automated Fuel Feeding: Equipped with integrated screw conveyors or hydraulic pushers that feed wood chips directly from the storage silo to the furnace, reducing labor costs by up to 80%.
- High-Efficiency 3-Pass Design: Flue gases are circulated through a precision-engineered 3-pass path, ensuring maximum heat absorption and achieving thermal efficiencies of 78% to 84%.
- Precise Combustion Control: Features Variable Frequency Drives (VFD) on the FD and ID fans, allowing the boiler to modulate its output based on your factory’s real-time steam demand.
- Low Carbon Footprint: Wood chips are a renewable energy source. Utilizing them makes your production process carbon-neutral and helps meet international sustainability standards.
- Uniform Temperature Distribution: The small, uniform size of wood chips allows for a consistent fire bed, preventing “hot spots” and pressure fluctuations.
- Advanced Ash Management: Integrated with automated ash extraction systems and high-efficiency Cyclone Separators to ensure a clean stack and minimal maintenance downtime.
Core Industry Applications
The Wood Chip Fired Boiler is a versatile powerhouse for:
- Plywood & Furniture Plants: Using internal wood waste and trimmings to generate free process steam.

Frequently Asked Questions
Can I use "Green" wood chips directly from the forest?
Fresh wood chips can have up to 50% moisture. While our boilers can handle higher moisture than standard units, we recommend seasoned or dried chips (below 25% moisture) for maximum efficiency and higher steam output.
What is the GCV of typical wood chips?
Depending on the species and moisture, the Gross Calorific Value (GCV) ranges from 3200 to 4500 Kcal/kg. Hardwood chips generally offer longer burn times and higher energy density.
Is this boiler IBR certified?
Yes. IndianBoilers.com manufactures wood-chip boilers in full compliance with Indian Boiler Regulations (IBR), ensuring safety and legal reliability for high-pressure industrial use.
How much steam can 1 ton of wood chips produce?
On average, 1 ton of dry wood chips can produce approximately 3.0 to 4.0 tons of steam, depending on the boiler's efficiency and the moisture content of the chips.
How do you automate the feeding of wood chips?
We offer automated screw conveyors or hydraulic push-ram systems that feed chips from a storage silo directly into the furnace based on real-time steam demand.
What type of grate is best for wood chips?
For smaller units, a Fixed Grate is sufficient. For larger, continuous industrial operations, we recommend a Reciprocating Grate or Traveling Grate to ensure automatic ash removal and uniform combustion.
Can the boiler handle different sizes of wood chips?
Our feeding systems are designed for standard industrial chips (approx. G30 to G50 size). We recommend a screening process to remove oversized chunks or "longs" that could jam the screw feeder.
How do you manage smoke and emissions?
By using Secondary Air Injection, we create a high-turbulence environment in the furnace. This ensures that wood gases burn completely, resulting in a clean, smoke-free chimney discharge.
Can I mix wood chips with other biomass like sawdust or briquettes?
Yes. Our furnaces are multi-fuel capable. You can co-fire chips with sawdust, pellets, or briquettes to manage fuel costs and availability.
How much ash does a wood chip boiler produce?
Wood is a very clean fuel, typically producing only 1% to 2% ash. This makes it much easier to manage than coal, which can produce up to 30% ash.
How often do the tubes need cleaning?
To maintain peak heat transfer, we recommend a monthly inspection. For 24/7 operations, we offer integrated Soot Blowers that clean the smoke tubes while the boiler is running.
What is the startup time for a wood chip boiler?
From a cold start, our boilers typically reach operating pressure in 60 to 90 minutes. Once warm, the response to steam load changes is very rapid.
Is the boiler safe to run unattended?
Our fully automated PLC systems monitor water levels, furnace temperature, and steam pressure. If any parameter goes out of range, the system triggers an alarm and executes a safe shutdown.
How do you prevent "Back-burning" in the fuel feeder?
We install Rotary Air Locks and independent water-sprinkler safety valves in the feed line to ensure the flame never travels back from the furnace into the fuel storage silo.
What is the typical ROI (Return on Investment)?
By switching from Diesel or Furnace Oil to wood chips, most industrial units reduce their fuel bill by 50% to 70%, achieving a full ROI within 10 to 15 months.
Is wood chip firing considered "Carbon Neutral"?
Yes. The CO2 released during the burning of wood is equivalent to the CO2 absorbed by the tree during its growth, making it a sustainable, eco-friendly energy choice.
How do you control particulate matter in the chimney?
We equip every boiler with a Multi-cyclone Dust Collector (MDC). For regions with strict environmental laws, we also provide Bag Filters or Wet Scrubbers to meet the lowest emission norms.
Can I get a subsidy for a wood chip boiler?
In many states, biomass-based steam generators qualify for capital subsidies or low-interest loans through agencies like IREDA. We provide the technical documentation to support your application.
Why choose IndianBoilers.com for wood-fired systems?
Based in Ahmedabad, we provide a rugged, "industrial-grade" design. Our boilers use thicker plates and higher-quality refractory than standard models, ensuring your investment lasts for decades, not just years.
