THE POTENTIAL IN USING TWO STEP DRYING TECHNIQUES FOR IMPROVING ENERGY EFFICIENCY AND INCREASING THE DRYING CAPACITY IN FUEL PELLET INDUSTRIES

摘要：

　　The use of wood fuel pellets has increased worldwide in recent years and pellet producers conclude that the lack of drying capacity is a barrier for increased production.In this study,a concept of two different driers was developed which called the “Two Step Drying Technique.The aim is to show the potential to increase drying capacity and energy efficiency improvements when introducing a second dryer in pellet plants.The study,based on an industrial packed moving bed dryer,shows that the drying capacity increases by 22% and that a pneumatic dryer is the best chose as a second dryer.
