CHARACTERISTIC FEATURES OF FLUIDIZATION OF BIDISPERSE BEDS IN SUFFOSION CONDITIONS

Experimental investigation of fl uidization of bidisperse beds of quartz sand and straw pellets at a large ratio of their equivalent diameters is carried out. The infl uence of the mass fraction of pellets on the rate of complete fl uidization of a disperse bed has been established. The inapplicability of the available dependences, based on the use of Ergun′s formula, for describing the results obtained is shown.
