The role of the airflow distribution plate in the boiling dryer
The airflow distribution plate in the boiling dryer has two functions: one is to support the material layer, and the other is to make the gas distribution uniform. The size, shape, distribution pattern, and porosity of the openings in the distribution plate have a crucial impact on the distribution of fluids. Uneven gas distribution can cause "circulation" in the bed, which tends to be extreme and can lead to "channeling" in some parts of the bed, while the rest is a dead bed. At this time,...
