Kostogryz K. Research and development of energy-saving tehnology of heat treatment of dispersible materials in fluidized bed aparatus

The thesis is devoted to research and development of heat treatment of disperse materials in fluidized bed apparatus. On the basis of researches the practical problems such as energy-saving and increasing of efficiency in production process of disperse materials as a perlite, fly ash cenosphere and sand were solved. The kinetic of a perlite dehydration in the fluidized bed was investigated. The mechanism of explosive destruction hollow ash cenosphere at their drying due to a superpressure of water vapours and deffects in microballons shell was established. The effect of carry-over from fluidized bed to achieve of simultaneous heat treatment and classifying of polydisperse materialswas used. The experimental base and procedure for accounts of fluidized bed launder-type apparatus for different materials and applications were developed. Detail designs and the designer documentation of perlite termal-preparation furnaces and heat-utilizer and dryind -sizing apparatus for sand and cenosphere with a launder-type fluidized bed were developed.
