to CFD simulations, coal boilers can handle operation with up to 100% of torrefied biomass without an obvious decrease of energy efficiency and fluctuation of the boiler load [14]. The direct application of torrefied biomass pellets in smallscale pellet boilers may not be advisable at this point unless boiler technology is adapted [15].

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
