Abstract

Bubbling fluidized bed technology is an invention that dates from the early 1920s (Winkler, BASF Ludwigshafen), therefore all its aspects have a rather long history. Heat transfer between bubbling fluidized beds and submerged surfaces is described by heat transfer coefficients related to the temperature difference between the heating surface and the bulk of the bed. There are different options to derive appropriate theoretical predictions, so relations between non-dimensional groups (e. g. Baskakov’s equations for gas convective heat transfer [1,2]) or even the dimensionally inconsistent but nevertheless useful Zabrodskij equation for particle convective heat transfer [3].
