✦ Synopsis

Partlcle-to-emulsion and mterpartrcle heat transfer rates were estimated in the range 1 5 G u/u,,,f 6 3 5, 0 69 c $ G 2 15 mm by drymg wet refractory partlcles m fluldlzed beds of smular dry partlcles of the same sues Overall particle-toemulslon heat transfer coefficients decrease roughly as the mverse of the particle diameter Particle to-particle heat transfer coefficients vary with the power-2 of the particle diameter and decrease as the flmdlzatlon velocity increases

## Abstract Fluidized beds are particularly favored as chemical reactors because of their ability to exchange heat through immersed heat‐exchange surfaces. However, little is known about how the heat‐exchange process works on a single‐particle level. The most commonly applied theory of fluidized be
