Today, in energy plants, fuel flexibility is desirable but still risky. Unconventional fuels can cause ash slagging, fouling and corrosion. Pilot testing is costly and time consuming. BIOFACT is the new accurate, user-friendly, fast and cost-effective tool to predict ash related issues for biomass and waste combustion and gasification for flexible operation.



Screen and characterize variable fuels such as agro-residues and bio-wastes
Sample specific prediction of ash related issues and mitigation measures
Risk management of slagging, agglomeration, PM1, fouling, corrosion and erosion
 Maximum output with lower quality fuels, while maintaining the reliability
 Operate more efficiently with challenging fuels in multi-fuels plants
Go beyond elemental analyses, improving fuel awareness and communication
 Visualize fuel data for any user group, from operators to the CEO, at any location

We are an engineering team with a proven expertise in biomass and waste combustion, specifically in fuel related phenomena including ash slagging, agglomeration, fouling and corrosion (>8 years in R&D initiated at the Université catholique de Louvain and the CEA). We have studied >200 biomass and waste fuel samples. No fuel is ever the same because ash composition depends on: fuel species, part of the plant, soil, fertilization, climate, age, harvesting, waste sorting and components, extraneous contaminants. The tool is exploited with independent consulting mandate. We protect privacy of Customer’s information.





“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
