Quantitative predictions of biomass ash risks in combustion

Numerical simulations for process optimization and fuel quality monitoring.

 Predict quantitatively ash related risks for solid fuels including low quality coals, variable agro-fuels and wastes
 Assess the reliability with challenging quality sources, in multi-fuel combustion and gasification plants
 Support the value chain: fuel procurement, plant design and retrofit, O&M troubleshooting, operations
✔ Improve fuel awareness and communication, visualizing fuel data for any user groups.

No fuel is ever the same: ash depends on the species but also the part of the plant considered, the soil composition, the fertilization and harvesting practises, and in case of a waste, the sorting process and trace elements. Therefore specific modeling is needed to evaluate each fuel.




Fuel screening and design

Ash chemistry optimization

Boiler and plant simulations

O&M challenge root cause


Slagging, agglomeration

Prediction of the slag load, sticking properties and agglomeration in the furnace


Fouling, deposition

Prediction of the volatilized sticky fly ash and hard deposits adhesion in convective passes


Fireside corrosion, erosion

Prediction of corrosive species occurrence in the high and low temperature boiler sections


Prediction of PM, SOx, HCl, HF, heavy metals emissions with ash and sorbents retention



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!

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.

BIOFACT is helpful in evaluating a fuel change or investigating a particular fuel related problems e.g. corrosion, emissions, deposits, etc.

About us

BIOFACT is an engineering firm focusing on quantitatively predicting ash related issues in thermal plants.

We support boiler manufacturers and operators to predict the extent of slagging, fouling and corrosion for the specific fuel, in each energy plant.

Simulations studies are 20%40% less expensive than comparable pilot experimental tests and are available with independent consulting mandates.
