Solid biomass fuels are available from a large number of different sources. Depending on local conditions, biomass resources are available in most of the world.
Experience with many types of biomass
The majority of our biomass plants are straw- and stalk-fired plants (baled material combustion) or plants fired on wood chips, saw dust, etc. The latter we characterise as bulk material suspension combustion.
However, our expertise covers a much wider range of biomass. Based on your specific fuel and needs, we can help you build a custom-designed plant.
Your fuel determines choice of technology
First of all we look at your fuel. We base your plant design on the physical and chemical properties of your fuel as well as your specific needs in terms of output – being hot water or steam – your labour situation, etc.
On the basis of our standard sieve analyse we distinguish between fuel characteristics which are close to our analyses, and fuels which are not fulfilling it.
Technologies for fuels close to our standard sieve analysis
For fuels close to our standard sieve analysis, a storage, feeding, and combustion system could consist of:
• Transport system from fuel storage to boiler house
• Boiler silo (either hydraulic or with snails)
• Firing silo with water-cooled feeding gastropods (or hydraulic feed hopper for smaller installations)
• Water-cooled vibrating grate (or air-cooled grate staircase for small plants)
A bran-fired boiler in BioWanze
Recently we delivered a new bran-fired steam boiler to supply steam for a new bioethanol factory in Wanze, Belgium.
The boiler is fired primarily with bran, which is a residue from the milling of wheat grain used for the production of ethanol. The steam from the boiler is expanded through a steam turbine to provide low pressure steam for the heating processes in the ethanol factory. The power is sold to the grid as green electricity.
Although bran has traditionally been used primarily for cow feed, the increasing amount of bran available and its favourable electricity prices have made the use of bran for generating power more profitable.

Additionally we are able to convert so-called multi-fuels.
Do you have contaminated waste wood, refuse-derived fuels, or solid recovered fuels?
Do you need the flexibility to burn more than one type of fuel?
In order to meet these needs, we have developed a new multi-fuel technology based on our unique experience with both biomass and waste-to-energy plants.
