EFFECTS OF USING DRAFT TUBES IN A CONTINUED SPOUTED BED DRYER

摘要

The interest shown in the use of biofuels such as pellets and briquettes has continued to grow in the European market.This paper presents the experimental results obtained from the drying of sawdust in a continuous spouted bed with various draft tube designs.The tests are performed using wet sawdust at various inlet and outlet gas temperatures.In a spouted bed dryer,the drying capacity depends on the heat capacity flow.The results show that draft tubes can improve the drying capacity.They also show that the utilised heat capacity flow is influenced by the design of the draft tube.
