Electrically Indirectly Heated Fluidized Beds

An important class of fluidized beds has been investigated, those that are indirectly heated by electrical elements inserted in the fluid flow before the bed. They are commonly used for drying, chemical synthesis, mixing, coating, and similar industrial processes. New models have been developed that are simple to manipulate and are determined by tests at only three flow rates. These models have a high degree of accuracy in the initial treatment region that is of importance in control studies.
