Abstract
A heat exchanger for exchanging heat between solid particles and a gas where the particles fall vertically through a column under gravitational forces and the gas flows upwardly in the column. The heat exchanger has at least one stage in the column including a stack of packing elements supported by a support having openings through which gas may flow at a velocity sufficient to form a loose fluidized bed of particles. A grill is positioned in the lower part of the column through which gas may flow to support a dense fluidized bed of particles.
