Our fuels range from biomass-based fuels to various solid waste fuels. The range of biomass-based fuels available for energy production is wide; from agricultural and wood residues, to slurries from industrial processes, recycled wood and purpose-grown energy crops.

 

No fuel is ever the same. For example, combustion properties are not only species-specific but also site-specific. Fertilization and the characteristics of the ground, where the biomass is grown, have an effect on ash content and ash melting, fouling and slagging temperatures, as well as emissions. Variations also exist within the various parts of the crop. The biomass properties of bark, branches and the stem wood are all different. The same for the biomass properties of the palm oil tree with its fronds,  empty fruit bunches and palm kernel shells.

Other solid fuels which are recovered from waste, like RDF (refuse derived fuels), SRF (solid recovered fuel) are various mixtures of different solid products and much harder to define. For each fuel we encounter worldwide, we repeatedly analyze all typical characteristics, like the content of volatiles, the high initial moisture content, the ash content and melting behavior, their content of sulphur, potassium or any possible heavy metals.

In general, woody biomass materials are common and popular fuels to burn. Biomass from agricultural crops or contaminated wood residues and SRF is more challenging in combustion. For all these types of fuels VYNCKE applies an advanced grate technology that achieves optimal performances.
