Results of previous studies that levels of ash, durability and density biopellet not meet the standard DIN. Results of previous studies that biopellet high ash content and does not meet the standards.
Pras, Apologies if I am completely mistaken. But if your goal is to remove ash to make the pellets a better fuel couldn't water wash the ash out? The pellets would then, of course, need to be dried. Or might the ash be shaken out on a mesh conveyor?
As the specific gravity and calorific value of sole palm wood pellets will be less it will results but if we can mix some charcoal or other better combustible additives the palm biopelltes ash content can be reduced.
