In an era of growing demands for environmental responsibility and cost-effective industrial heating, pellets are becoming an increasingly sought-after solution. These granulated fuel units made from renewable feedstock combine high calorific value, stable combustion, and minimal environmental impact. In this article, we explore the key aspects of using pellets in industrial applications: from technical specifications to practical recommendations for selection and storage.
What Are Pellets and What Are They Made From?
Pellets are cylindrical, compressed granules manufactured from biomass: wood sawdust, wood chips, sunflower husks, straw, and other agro-industrial byproducts. Production requires no chemical binders: natural lignin present in the raw material, activated by heat and pressure, ensures granule durability.
Main Types of Industrial Pellets
| Pellet Type | Raw Material | Calorific Value | Ash Content | Key Features |
|---|---|---|---|---|
| Wood Pellets | Softwood/hardwood species | 17–19 MJ/kg | ≤ 0.7% | Low ash content, clean combustion, suitable for automatic boilers |
| Sunflower Husk Pellets | Oil extraction byproducts | 16–18 MJ/kg | 3–6% | High heat output, cost-effective pricing, requires more frequent ash removal |
Advantages of Pellets for Industrial Heating
✅ Environmental Sustainability
Pellet combustion releases only the CO₂ absorbed by the plant during its growth cycle — a closed carbon loop. The absence of sulfur and heavy metals reduces strain on filtration systems.
✅ Economic Efficiency
Compared to coal, diesel, or natural gas, pellets deliver stable energy costs unaffected by fluctuations in global fossil fuel markets.
✅ Process Automation
Standardized size and free-flowing properties enable seamless integration into automated fuel feed systems, reducing labor costs and enhancing boiler room reliability.
✅ Logistics & Storage Convenience
Pellets are packaged in 15–25 kg bags or supplied in bulk via big-bags. When stored properly, they resist caking and occupy less space than firewood or coal.
✅ Compliance with International Standards
High-quality pellets are certified to ENplus and ISO 17225 standards — essential for export operations and partnerships with European clients.
Key Selection Criteria for Industrial Pellets
🔹 Calorific Value & Moisture Content
Optimal moisture: ≤ 10%. Higher levels reduce combustion efficiency and may cause condensation in flue systems.
🔹 Mechanical Durability
Granules must withstand transportation and feeding into boilers without disintegrating. Low durability leads to dust formation, impairing automated system performance.
🔹 Ash Content & Ash Composition
For automatic boilers, pellets with ash content ≤ 1.5% are preferred. Higher ash levels necessitate more frequent equipment maintenance.
🔹 Certification & Documentation
Always request quality passports, test reports, and compliance certificates. This is especially critical for export contracts or government procurement.
🔹 Supply Chain Reliability
Choose manufacturers with secured raw material sources and adequate storage capacity — this ensures uninterrupted supply during the heating season.
Storage & Preparation Guidelines
🔹 Storage Conditions: Dry, well-ventilated facility with air humidity ≤ 60%. Avoid direct contact with concrete floors — use pallets.
🔹 Shelf Life: Up to 2–3 years without loss of calorific properties, provided storage conditions are maintained.
🔹 Pre-Use Preparation: If needed, sieve pellets to remove dust — particularly important for boilers with pneumatic feed systems.
