Mathematical Model of a Flash Drying Process
The model of the flash drying process presented in this paper was initially developed for the specific purpose of drying subbituminous coal and was successfully used for that purpose in the case of a 60 MW plant although the results of that application remain restricted by confidentiality agreements.
