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

Sample specific predictive Dashboard and Report

   Step 1.    Send us the fuel composition 

   Step 2.    Get your fuel specific study in 24h

Sample specific prediction of combustion operational risks and most suitable boiler technologies
 Engineering advice to mitigate ash risks, such as temperature profiles, additives 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)

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

They trust us

“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
