Wood sawdust—the clean, fine residue from sawing and planing—becomes a high-performance, low-ash industrial fuel when properly dried and densified. Converted into sawdust pellets (6–8 mm) or sawdust briquettes (90 mm), it replaces coal and furnace oil in boilers, thermic fluid heaters (TFHs), hot-air generators, and gasifiers with predictable heat release, easy handling, and cleaner stacks. Bhavishya Biofuels sources virgin sawdust from compliant wood processing lines, stabilizes moisture, and delivers consistent, specification-backed fuel across India.

What Exactly Is Wood Sawdust Fuel?

Wood sawdust biomass is the fine particulate generated during primary and secondary wood processing. When left loose, it is bulky and difficult to meter. Densification into pellets or 90 mm briquettes dramatically improves bulk density, storage, and flow—unlocking steady boiler operation and reliable heat rates. Our feedstock policy prioritizes clean, untreated wood (no MDF, laminates, paints, or contaminated scraps), protecting combustion quality and downstream emissions.

Why Choose Sawdust Pellets or Briquettes?

• High GCV with fast ignition: Properly dried sawdust delivers strong calorific value and lights quickly, stabilizing steam curves.
• Ultra-low ash: Clean, virgin wood typically yields very low ash, reducing housekeeping, disposal, and bag filter loading.
• Consistent sizing: 6–8 mm pellets and 90 mm briquettes feed smoothly in screws, rotary valves, and grate systems.
• Lower SO₂ risk: Wood has naturally negligible sulfur compared with many solid fossils, easing compliance.
• Spec-driven procurement: You can order to ISO 17225-2 wood-pellet parameters for moisture, ash, durability, and fines.
• Ready for co-firing: Sawdust pellets blend well with other biomass streams and suit power/utility co-combustion lines.

Fuel Formats We Supply

1) 6–8 mm Sawdust Pellets

Designed for automated feeding—silo storage, screw conveyors, and pneumatic transfer. Pellets deliver narrow size distribution, high durability, and low fines to protect feeders and filters. Ideal for package boilers, TFHs, hot-air generators, and co-firing.

2) 90 mm Sawdust Briquettes

Excellent for manual or semi-automatic feeding; high bulk energy per truck reduces freight per kcal. Uniform diameter supports steady combustion on grates and in kiln/heater applications.

3) Screened Sawdust (Loose, Project-Specific)

For clients with on-site densification or specialized gasifiers, we can supply screened, kiln-dried sawdust with agreed particle-size ranges. Recommended only where storage and dust management are well engineered.

Typical Technical Parameters (Guidance Ranges)

Values vary by species, season, and process. We dispatch with truck-wise QA reports as needed.

• Gross Calorific Value (GCV): High for woody biomass; specify a minimum GCV target in your PO for consistency.
• Moisture (as-received): Typically single-digit to low-teens; kiln-dried pellets target lower moisture for fast ignition.
• Ash: Very low for clean, virgin wood; avoids frequent hopper evacuation and reduces particulate loading.
• Pellet diameter: 6–8 mm (state preference); Briquette diameter: 90 mm (length tailored to feeder).
• Fines & durability (pellets): Low fines and high mechanical durability to protect screws/valves and maintain flow.
• Bulk density: Densified formats greatly improve ₹/kcal freight efficiency vs. loose sawdust.

Where Sawdust Biomass Performs Best

• Textiles & dyeing: Stable steam on package boilers and TFHs while easing SO₂ and ash burdens.
• Food & beverage: Clean combustion for hot air and process steam in snacks, spices, bakeries, distilleries, and dairies.
• Paper & board, chemicals, pharma: Predictable heat input with low fouling risks.
• Bricks & ceramics: Dense briquettes support longer burn cycles and steady bed behavior.
• Power & utilities: Wood pellets India supply is co-firing ready; pellets blend smoothly with other agro residues.

Combustion & Boiler-Tuning Tips

• Fuel prep: Keep pellets/briquettes dry; store on pallets with roofed, ventilated sides. Follow FIFO inventory.
• Feeding: Pellets prefer clean, dry screws and guarded inlets to avoid bridging; briquette length should match feeder pockets.
• Air management: Begin with settings similar to mixed woody firing; trim using stack O₂/CO to minimize unburnt carbon.
• Bed temperature (FBC): Operate within OEM windows to avoid sintering; wood’s low ash helps keep beds clean.
• Particulate control: Multicyclones/bag filters handle low-ash dust well; maintain tight ducting and hopper routines.
• Safety: Enforce no-smoking zones and spark arrestors; maintain dust housekeeping around conveyors and silos.

Standards, Compliance & Documentation

We align our declarations with parameters from the ISO 17225-2 series for graded wood pellets (where applicable): moisture, ash, mechanical durability, fines, and size class. On request, each truck can be supported with a pre-dispatch lab sheet covering moisture, ash, and GCV. For export-style specs (e.g., ENplus A1 ranges), tell us your target values and we’ll propose feasible limits based on local species and process routes.

Procurement, Pricing & Logistics

• Contract models: Spot lots, monthly schedules, or annual agreements with optional price indexation.
• Load formats: Full-truck loads (FTL); tarpaulin-covered. Jumbo bags available for select sites.
• Pan-India supply: Aggregation from multiple wood hubs provides resilient, year-round volumes.
• QA: Truck-wise batch tagging; optional third-party testing; photo documentation on request.

FAQs (SEO-Focused for Buyers & Boiler Teams)

What is the GCV of sawdust pellets or briquettes?

GCV of sawdust is high among biomass options when moisture is controlled, enabling sawdust pellets and briquettes to replace low-grade coal in many boilers and TFHs. We include GCV in our batch-wise reports.

Are sawdust pellets better than briquettes?

Pellets (6–8 mm) are ideal for automated feeding, silo storage, and pneumatic transfer. Briquettes (90 mm) shine where manual/semi-auto feeding is used and you want excellent ₹/kcal freight efficiency.

What ash levels should I expect from wood sawdust biomass?

For clean, virgin wood sawdust, ash is typically very low—far below many agricultural residues and most Indian coals—simplifying housekeeping and filter operations.

Can I co-fire wood pellets with other biomass?

Yes. Sawdust pellets blend well with agro residues to tune flame stability and ash behavior, useful in AFBC/CFBC and grate systems.

Is there any restriction on wood types or add-ons?

We prioritize untreated wood only: no MDF/particleboard with binders, no painted/varnished wood, and no plastics or metals—protecting combustion quality and emissions.

How do I compare costs versus coal or FO/LDO?

Use a ₹/kcal comparison, not just ₹/tonne or ₹/litre. High GCV, lower ash handling, reduced SO₂, and cleaner operations often deliver a lower total cost of heat.
