Methods for calculating the main practically important types of convective dryers for dispersed and liquid materials are outlined. The main regularities of their hydrodynamics and heat and mass transfer, regime parameters and structural elements are considered. The properties of heat carriers and wet materials, the basics of thermal analytical calculation of drying plants and exergy analysis, and energy saving methods are briefly described. Examples of calculation of the main types of industrial convective dryers are given.For students of higher education institutions in energy and technological specialties. It may be useful for graduate students and undergraduates, scientific and engineering workers.
