Jan Oltvoort 

 R&D, Proces Engineer

  • Research experience in biomass processing in several academic projects
  • Practical experience as process technician in several companies

Jan Oltvoort studied Chemical engineering at the University of Twente and during his internship period, he was working with Patrick to further develop the debottlenecking of the torrefaction process. Jan has proven to be a valuable force in the R&D and design of the Yilkins technology scope. In addition, he recently had a position in the field of small-scale combustion of biomass. He has a very analytical mind, but can also “feel” the phenomena he’s dealing with. Jan shares the passion of the Yilkins business concept and has the natural tendency to be exited to bring biomass conversion to the next stage in the energy transition.

Yilkins has substancially improved the torrefaction process. Yilkins pellets are the proof

  • Low chlorine content
  • High water resistance
  • High calorific value; product from 20 to 23 GJ/t
  • Considerable less pollution of the combustion plant
  • Combustion performance of boilers improves up to 10%
  • High abrasion resistance and low dust forming
  • Low volatile components concentration
  • High energy density
  • No additives needed to pelletize

Several researches point out that the torrefaction process sets chlorine free, which results in a significant reduction of this element in the end product from 50% to 90% in some specific cases. Therefore, the Yilkins pellets are the solution when a low chlorine level is required.

Because the Yilkins pellets are highly impermeable, they can be stored outdoor with minimal degradation risks. That means also a huge advantage for transportation purposes.

Due to the high calorific value the capacity of the biomass boiler can be increased – or the investment reduced with the same capacity – and more energy will be produced in the same combustion conditions.

The use of Yilkins pellets as biofuel produces less pollution in the boilers. That means a reduction in the operational costs due to less maintenance operations and less stops of the boilers.

Less pollution and the higher calorific value of the Yilkins pellets increase the combustion performance of the boilers up to 10%.

The high abrasion resistance of Yilkins pellets decreases significantly the dust forming in the process. The result of this is less production waste and considerable lower danger of dust explosions.

Due to the torrefaction process, volatile components in the feedstock, like chlorine, become unlocked in higher percentage. That reduces considerably the level of emissions of the end product.

The high energy density of Yilkins pellets makes them more water-resistant and less dusty than other pellets. This reduces the costs of transport and storage of the product.

The natural polymers of the biomass are better preserved with the Yilkins torrefaction technology. The use of any kind of binding agent for optimal pelletizing can be avoided, which reduces the production costs.
