01Analysis portfolio

Fuel characterization, complete.

Four analysis packages cover the full thermal characterization of solid fuels. Each can be commissioned alone or as a complete suitability programme.

Results are reported with measurement uncertainty, assessed against thermal conversion requirements and translated into process-relevant conclusions — not just a data sheet.

01

Proximate Analysis

Moisture · Ash · Volatile matter · Fixed carbon

The first gate for any thermal project: the four-value fingerprint that determines handling behaviour, combustion profile and preliminary gasification performance.

ParameterDetailMethod
Moisture contentTotal moisture as receivedISO 18134
Ash contentResidual mineral mass after oxidationISO 18122
Volatile matterThermally released fractionISO 18123
Fixed carbonDetermined by difference—
02

Ultimate Analysis

C · H · N · S · O · Cl

Elemental composition that drives stoichiometry, emissions modelling and downstream syngas chemistry — the basis for process design calculations.

ParameterDetailMethod
Carbon (C)Elemental carbon fractionISO 16948
Hydrogen (H)Elemental hydrogen fractionISO 16948
Nitrogen (N)Fuel-bound nitrogen, NOx precursorISO 16948
Sulfur (S)SO₂ precursorISO 16967
Chlorine (Cl)Corrosion & dioxin pathway indicatorISO 16967
Oxygen (O)Determined by difference—
03

Calorific Value

GCV · NCV · energy density

Measured energy content — the number every business case is built on. Reported as gross and net calorific value with energy density for logistics planning.

ParameterDetailMethod
Gross calorific valueBomb calorimetry, constant volumeISO 18125
Net calorific valueCalculated from H content and moistureISO 18125
Energy densityGJ per m³ for transport economics—

Ash Analysis

Fusion behaviour · composition · slagging risk

Ash decides reactor availability. Fusion temperatures and oxide composition reveal slagging, fouling and bed agglomeration risk before they become operational problems.

02Sample workflow

Ensuring representative results.

Analytical quality is decided before the sample reaches the bench. Follow four simple rules and your results will carry full engineering weight.

Biomass fuel sample preparation on a laboratory tray
01

Sample preparation

Collect representative samples following solid biofuel sampling standards — proper size reduction and homogenization before submission.

02

Sample size

Minimum 2 kg per complete analysis package, with additional material retained for repeat verification if required.

03

Storage & transport

Airtight containers, clearly labelled, transported within 48 hours to preserve moisture integrity.

04

Documentation

Source, collection date, storage history and intended application — the context that makes results actionable.

03Reporting

Results you can take to an engineer — or a lender.

Every report closes the loop between measurement and decision.

  • 01Detailed analytical results with measurement uncertainty
  • 02Fuel quality assessment against thermal conversion requirements
  • 03Gasification suitability evaluation
  • 04Environmental impact indicators
  • 05Comparative analysis against reference fuel benchmarks
  • 06Technical consultation on the results and next steps
04FAQ

Before you send a sample.

Following our sample guidelines: a representative sample of at least 2 kg of solid fuel, sealed airtight, delivered to the laboratory within 48 hours and accompanied by basic documentation of origin and handling. Representative sampling matters more than quantity — a perfect analysis of an unrepresentative sample is a wrong answer.

Proximate analysis (moisture, ash, volatiles, fixed carbon), ultimate analysis (C/H/N/S/O), calorific value (GCV/NCV) and ash behaviour — fusion temperature, composition and slagging/fouling indices. Together they determine whether a fuel can be converted reliably and what the plant must be designed to handle.

Yes. Results are reported with measurement uncertainty and assessed against thermal conversion requirements — the deliverable is a process-relevant conclusion, not just a data sheet.

That is what the data is for. As vendor-neutral consultants we translate results into technology screening and design decisions — and we tell you honestly if a fuel does not support the concept you had in mind.
