  • Process and heat exchanger for continuous circulation of fluidized powder in heat exchange with a hot gas
    Patent number: 3974572
    Abstract: The invention relates to a process for continuously circulating a fluidized powder in a heat exchanger between a heat-carrying gas and a fluidized powder, and to heat exchangers using this process. In the process according to the invention, the circuit through which the fluidized material circulates is in the form of two series of tubes, merely one series of ascending tubes and another series of descending tubes, and the material is fluidized in these tubes with a density that is higher in the descending tubes than in the ascending tubes. The invention applies to any heat exchanger between a gas and a powder and, more particularly, to installations, for calcining hydrated alumina.
