What this product reference covers.
Biomass fuels are renewable organic materials used directly or densified into briquettes or pellets; feedstock and processing govern quality.
Products within the family.
Names used in commerce can overlap. Use the nominated standard and exact grade rather than relying on a generic product label.
Biomass briquettes
Biomass briquettes is a recognised biomass & briquette fuel category whose exact composition, grade limits and suitability must be confirmed from the governing specification and equipment requirement.
Wood pellets
Wood pellets is a recognised biomass & briquette fuel category whose exact composition, grade limits and suitability must be confirmed from the governing specification and equipment requirement rather than inferred from the generic label.
Agro-residue pellets
Agro-residue pellets is a recognised biomass & briquette fuel category whose exact composition, grade limits and suitability must be confirmed from the governing specification and equipment requirement rather than inferred from the generic label.
Loose biomass
Loose biomass is a recognised biomass & briquette fuel category whose exact composition, grade limits and suitability must be confirmed from the governing specification and equipment requirement rather than inferred from the generic label.
What the product is built from.
| Component | Technical role |
|---|---|
| Combustible organic fraction | Provides the principal energy released during combustion. |
| Moisture | Affects net energy, storage stability, handling and ignition. |
| Mineral matter / ash-forming constituents | Influences residue, slagging, fouling and emissions. |
| Minor sulfur, nitrogen and trace elements | Influence emissions, corrosion and ash chemistry. |
Define the decision before selecting the panel.
- 01
Confirm new biomass & briquette fuel identity, grade and fitness for the intended application.
- 02
Detect contamination, degradation, mixing or storage-related change.
- 03
Investigate abnormal equipment, combustion, filtration or handling behaviour.
- 04
Establish a representative baseline for later comparison.
- 05
Support specification, maintenance and root-cause decisions with corroborated evidence.
What each result contributes.
“High” and “low” are directional investigation prompts, not pass/fail decisions. Corroborate them using the correct specification, baseline and companion evidence.
| Test / parameter | Typical methods | Why it matters | Possible causes when high | Possible causes when low |
|---|---|---|---|---|
| Gross calorific value | ASTM D5865 / ISO 1928 | Quantifies combustion energy for purchasing and boiler calculations. | Higher fixed carbon and lower moisture/ash. | High moisture, ash, weathering or low-energy feedstock. |
| Total moisture | ASTM D3302 / ISO 589 | Affects handling, net energy, storage and combustion efficiency. | Wet feedstock, exposure, poor drying or sampling bias. | Drying, protected storage or loss of representative fines. |
| Ash | ASTM D3174 / ISO 1171 | Estimates inorganic residue, slagging burden and non-combustible content. | Mineral matter, soil contamination or high-ash raw material. | Cleaner feedstock, washing or biased sampling. |
| Volatile matter | ASTM D3175 / ISO 18123 | Supports combustion, ignition and fuel-rank interpretation. | High volatile organic fraction or lower-rank material. | Carbonised material, weathering or higher fixed-carbon fraction. |
| Sulfur | ASTM D4239 / ISO 19579 | Supports emissions, corrosion, fuel selection and ash-behaviour decisions. | Sulfur-bearing mineral or organic constituents. | Low-sulfur feedstock or blending with cleaner material. |
Condition-monitoring application.
Once the product is in service, the question changes from “does it meet a product requirement?” to “what has changed, why, how confident are we and what action is proportionate?”
- 01Use a stable, representative sampling point and document operating hours, top-ups, transfers and maintenance.
- 02Trend method-consistent results rather than treating one value as a complete diagnosis.
- 03Separate new-product conformance from in-service condition and machine-wear questions.
- 04Escalate correlated evidence and rate of change; confirm surprising results before major action.
