Abstract
In a fluidized bed there is immersed an internal heat-exchanger connected to a heat-transfer fluid discharge line which feeds an external heat-exchanger fitted in a fluidizing gas delivery line with a by-pass line connected to a flow-control valve so that the heat withdrawn from the fluidized bed and not used is reintroduced therein by means of the fluidizing gas.
