Today, fuel flexibility in energy plants is highly desirable but risky. Non-conventional, cheaper fuels might cause ash slagging, fouling and corrosion, which are open questions. Pilot testing is useful but costly and time consuming. Fortunately, BIOFACT is a new accurate, user-friendly and cost-effective tool to rapidly predict operational risks for bio-waste fuels in combustion.


Screen and quickly characterize fuels such as agricultural residues and bio-wastes
Go beyond elemental analyses: improve fuel awareness
 Highly visualize fuel data for any user group, from operators to the CEO, at any location
Sample specific prediction of ash related issues and identify countermeasures
 Deal with the high variability of inorganic contents in opportunity biomass fuels
Ensure high performance multi-fuels plants, allowing industrial valorization of bio-wastes

How it works

   Step 1.    Send us the fuel composition 

   Step 2.    Get your fuel specific study

 Dashboard in 24h: sample specific prediction of combustion boiler operational risks
 Technical Report in 1 week: detailed thermochemical boiler design calculations and engineering advice to mitigate ash risks (T profiles, air splittings, additives optimized dosage, etc.)

We have studied 200+ biomass and waste samples. No fuel is ever the same: biomass ash composition depends on species, part of the plant, soil, fertilization, climate, harvesting, etc.!





   Examples (available upon request)

 Comparing multiple samples of coffee grounds
Comparing multiple samples of an unconventional wood
 Evaluating the use of mineral additives with an agro-residue
 Evaluating the use of bed materials with a low quality wood
 Defining specs limits for samples of SRF to limit corrosion risk
 Evaluating a sample of thermally treated pellets
 Screening co-firing, introducing a new fuel in a mixture
 Studying different fractions of a set of RDFs
 Calculating BA, FA, PM molten fraction, sticking probabilities, viscosity and compositions for a boiler design
 Calculating release fractions and BA embedding of critical elements and heavy metals for a boiler design
 Quantifying condensation species and flue gas corrosiveness in a boiler sections
 Heat transfer computations for clean/heavy fouled tubes, steady state deposits, max steam T for design
 Sensitivity analysis on ash risks for variable composition of an agro-pellet

“Burning biomass, especially agro-biomass, offers a great potential, but it comes along with challenges such as slagging and corrosion. BIOFACT allows to anticipate the combustion behaviour of any biomass, giving precious information to any boilers operators and manufacturers”  •  Bioenergy Europe 

BIOFACT gives a double check on fuel properties for internal use, but graphical presentation also help to explain to customers in an easy and comprehensive way what are the risks of different fuels”  •  Vyncke

BIOFACT is a useful tool when evaluating a fuel change or investigating a particular fuel related problem e.g. corrosion, emissions, deposits, etc.”  •  Jansen Boilers

BIOFACT can help us to select or give ideas for the proper grate / combustion system without making real tests ” •  Akkaya Boilers 

BIOFACT is of great help for us in order to establish beforehand the characteristics of a fuel and therefore better prepare our systems ” •  Biomass Waste BaW Energy
