Pneumatic conveying dryers pilot plant size

Similar results are reported from the drying of bark and peat in superheated steam in a pilot-plant pneumatic conveying dryer [22], The results are presented as a convective apparent heat-transfer coefficient, defined with the assumption that the temperature of the particle surface coincides with the saturation temperature of the transport steam. This transfer coefficient shows a clear dependence on the moisture content of the particles and the particle sizes. Fyhr [23] presented a model for a pneumatic conveying steam dryer. The dryer model consists of two submodels, one for the single particle and the other for the hydrodynamics of gas and particles in the dryer.
