Hazelnut shells for biomass fuel

A detailed, procurement-ready overview of hazelnut shells used as biomass fuel — including common shell formats, fuel specification markers (moisture, ash, particle size), handling and storage practices, safety considerations, and packaging/logistics options for continuous industrial supply.

Back to applications

Best for: biomass boilers, industrial heat generation, dryers, greenhouses, and facilities seeking an agricultural residue fuel with predictable handling when properly specified and cleaned.

Where it fits

Hazelnut shells are a valuable by-product of hazelnut processing and can be used as a biomass fuel for heat generation. In industrial settings, shells are typically combusted in biomass boilers or burners designed for agricultural residues. The key value proposition is practical: shells can help reduce reliance on fossil fuels while supporting circular use of processing residues.

Unlike food-grade ingredients, shell fuel performance is driven less by taste and more by consistency. Procurement teams usually focus on: moisture control (for stable combustion), ash behavior (to manage maintenance and slagging), particle size distribution (for feeding systems), and contamination control (to protect equipment). These variables are the difference between a fuel that runs smoothly and one that causes feed bridging, excessive ash, or unplanned downtime.

We support industrial users by aligning the shell format to your equipment: loose shells for simple conveyance, crushed shells for more uniform feeding, and densified formats (pellets/briquettes) where higher bulk density and automated handling are required. For long-term programs, we align packaging, documentation, and shipment cadence to your consumption profile and storage capacity.

What “good” looks like for shell fuel

A strong shell fuel spec reads like an operations document: it defines the format, cleanliness expectations, moisture range, particle size distribution, and a delivery/handling plan that fits your receiving and storage reality.

  • Stable combustion: moisture managed for consistent flame and reduced smoke/soot risk.
  • Predictable ash: ash level and behavior aligned to your boiler’s cleaning schedule.
  • Feed reliability: particle size and fines controlled to reduce bridging or dust issues.
  • Cleanliness: minimized foreign material to protect screws, conveyors, and grates.
  • Logistics fit: packaging and transport aligned to unloading method and storage.

Recommended formats

Typical starting points for trials and continuous supply. We align shell cleanliness, particle profile, and packaging to your combustion system and material handling setup.

  • Loose cleaned shells — standard option for suitable biomass boilers and simple bulk handling.
  • Crushed shells — more uniform feed behavior for screws/augers and controlled dosing.
  • Shell pellets / briquettes (where available) — higher bulk density and consistent handling for automated systems.
  • Screened fractions — reduced fines or defined particle bands based on your feeding requirements.

Technical considerations

Variables that impact combustion stability, equipment reliability, and day-to-day operations.

  • Moisture control: affects ignition, efficiency, smoke/soot, and storage stability.
  • Ash content & behavior: drives cleaning frequency and risk of clinker/slag formation.
  • Particle size distribution: influences feed consistency, bridging risk, and dosing accuracy.
  • Fines/dust management: helps reduce dust load, explosion risk areas, and handling mess.
  • Contamination control: foreign material (stones/metal/plastics) can damage conveyors and grates.
  • Storage & biodegradation: moisture and ventilation matter to avoid odors, heating, or mold growth.

Packaging approach

Packaging and transport are chosen based on unloading method, storage design, and whether you need loose material or densified fuel.

Common solutions include bulk truck/containers for loose shells, big bags for controlled site handling, or palletized bagged formats for smaller programs. For longer routes, protection from rain ingress and moisture pickup is essential to preserve fuel performance.

Typical specification markers

Below is a practical checklist used by procurement and operations teams when buying shells as fuel. We align each item to your combustion system (grate, screw-fed, pneumatic), your storage setup, and your route/season.

ParameterHow we align it
FormatLoose shells, crushed shells, screened fractions, or densified formats (pellets/briquettes)
MoistureManaged to an agreed target range to support stable combustion and storage
Ash contentAligned to your maintenance expectations; used to forecast cleaning and disposal volumes
Particle sizeDefined distribution or screening plan to match your feeding equipment and reduce bridging
Fines / dustControlled via screening; handling guidance provided for dust-sensitive sites
Foreign materialCleanliness expectations defined (stones/metal/plastics minimized) to protect equipment
Bulk densityConsidered for transport efficiency and silo/bin behavior; densified options where required
DocumentationLot identification, shipment paperwork, and agreed quality checks for receiving
Packaging / transportBulk, big bags, or bagged/palletized solutions aligned to unloading and storage

Final target values depend on your combustion technology and site handling constraints. For continuous users, the most important success factor is consistent format + moisture + cleanliness, supported by a predictable delivery plan.

Handling & storage guidance

Shell fuel is operationally simple when storage conditions are controlled. Most issues come from moisture pickup, poor ventilation, or inconsistent particle profiles.

  • Keep dry: protect from rain ingress; moisture drift affects efficiency and can cause handling problems.
  • Ventilate appropriately: avoid tightly sealed damp storage that can lead to odors or material degradation.
  • Match to equipment: choose loose vs crushed based on augers, conveyors, and grate design.
  • Plan for dust: define housekeeping and dust control around transfer points.

Combustion system fit

Performance depends on how shells are introduced and burned. Aligning format and particle profile to your system reduces downtime and improves stability.

  • Grate systems: can tolerate wider particles; focus on moisture and cleanliness.
  • Screw-fed systems: prefer controlled particle profile to prevent bridging and uneven feed.
  • Pneumatic conveyance: needs careful fines/dust strategy and consistent density.
  • Mixed-fuel programs: shells can be blended, but define ratio and handling impacts.

Safety & compliance notes

Biomass handling includes risks that should be managed operationally, especially around dust and hot work.

  • Dust: manage accumulation; use appropriate controls at transfer points.
  • Hot surfaces: keep storage away from ignition sources; follow site procedures.
  • Receiving checks: simple visual inspection + documentation reduces surprises.
  • Traceability: lot identification supports consistent performance over time.

FAQ

Which format is most common for hazelnut shells used as biomass fuel?

Most industrial users start with cleaned loose shells for direct combustion in suitable biomass boilers. If you need more predictable feeding (especially with screws/augers) or improved transport efficiency, crushed shells or densified formats (pellets/briquettes) may be a better fit.

Can you match a target particle size or screening requirement?

Yes. We can support screened fractions (reduced fines or defined size bands) to align with your feeding and conveyance system. Defining particle distribution is one of the best ways to reduce bridging and improve stable dosing.

What are the key quality checks on arrival?

Most sites check moisture condition (no rain ingress), cleanliness (foreign material), and particle consistency versus the agreed format. For continuous programs, lot identification and consistent paperwork help maintain stable performance across shipments.

Do you support long-term supply programs?

Yes. We structure multi-shipment programs with consistent specifications, batch documentation and forecast-based planning. If you share your monthly consumption and storage method, we can propose packaging and a delivery cadence that fits your operations.
