ABSTRACT
Impinging jets of various congurations are commonly used in numerous industrial drying operations involving rapid drying of materials in the form of continuous sheets (e.g., tissue paper, photographic lm, coated paper, nonwovens, and textiles) or relatively large, thin sheets (e.g., veneer, lumber, and carpets), or even beds of coarse granules (e.g., cat or dog food). In this chapter, we will not examine the last-mentioned application, which is a novel operation in which hot jets are directed normally onto thin beds of pellets transported on a slow-moving conveyor. The jets pseudo¶uidize the bed to ensure good gas-solid contact needed for effective drying.
