Heat transfer by convection to a moving bed

Abstract

A critical review of the literature pertaining to melting and moving beds has been made. The amount of reliable information is shown to be limited. A general review of fixed bed heat transfer literature is also given to illustrate intraparticle temperature distribution and wall effects, and to indicate the different problems in fixed and moving bed heat transfer. Following Rose's work (1) on melting beds of granular solids, an apparatus was designed and built as a tower melter. Experiments on this apparatus showed two heat transfer regions, the preheating and melting zones.
The problem of calculating the thermophysical properties of glass and alumina ceramic is considered in some detail and experimental values are shown to agree well with theoretical predictions.
