Abstract
Fluidizing apparatus comprises a grid defining cavities and main fluidizing gas blower channels connected to these cavities. Complementary channels pass through openings in swellings at the intersections of the cavities. Their upper ends are above the level of the grid. They are adapted to blow a complementary gas into an active area disposed above each swelling. A heat exchanger is adapted to exchange heat with the fluidized bed. It comprises at least one tube shaped so as to extend over the grid and through a plurality of these active areas. The rate of heat exchange may be modified by altering the complementary gas flowrate, without modifying the fluidization velocity.
