Abstract
The invention discloses a process and apparatus for the heating or cooling of light solid particles having a low free-fall speed, by means of flowing gas-solid exchangers. The process makes it possible to heat or cool light solid particles dispersed in a gas flow by contacting them with a countercurrent flow of heavy solid particles having a greater final free-fall speed and that are hot or cool in relation to the light particles, thus effecting a heat transfer between the particles.
