HD PELLETS
STUDIES AND TEST RESULTS

With HD technology, it is technically possible to produce pellets of theoretically any length for the first time. However, it would not be sensible to just produce the longest pellets possible now. We rather use the wide variety of possible settings for the HD technology specifically to create pellets with an ideal length distribution for pellet burners.

Only with defined homogeneous length distribution do wood pellets become pellets optimised for combustion. With HD pellet technology, it is possible to increase the average length from approx. 16 mm to approx. 22 mm and at the same time reduce the maximum length from 40 mm to 30 mm – an absolute novelty for wood pellets.

The end surfaces, owing to their brittle and porous form, are the main cause of increased rubbing, abrasion and dust production. One metric ton of conventional pellets, on average, consists of around 2.2 million individual pellets. This gives an end surface of around 70 m2 on average. One metric ton of HD pellets, thanks to the high proportion of pellets in the ideal length range, consists of just 1.5 million individual pellets on average with approx. 45 m2 of end surface. This results, quite simply, in significantly less fine particles and dust.

Before: With conventional production technology, the proportion of pellets in the ideal length range was generally only around 45% at the time of loading. After: By converting to HD technology, the proportion of pellets which are optimal for combustion regularly rises to some 85%.

Changing pellet breakage in the transport chain: Wood pellets are put under a lot of strain during transportation and handling. The highest production quality thanks to the HD pellet technology allows for optimal condition and size of pellets right up to the customer’s fuel store.

Studies by various research institutions have determined, independently from one another, that too many short pellets and fragments can also affect emissions: HD pellets thus has up to 37% less CO in the flue gas in comparative tests thanks to their homogeneous size*. *Combustion and material handling assessment of wood pellets with improved physical properties, Technology and Support Centre in the Competence Centre for Renewable Resources, 03/2014
