Abstract
A heat exchanger system includes a first heat exchanger followed by a second heat exchanger disposed in a dense fluidized bed, the second heat exchanger being made up of a plurality of nests of tubes disposed along the path of the particles in suspension in the dense fluidized bed. The second heat exchanger is provided with at least two feeds situated on either side of its center, each of the feeds receives a distinct mixture of the input fluid and of the output fluid of the first heat exchanger, so that the temperature of the fluid fed into each of the nests is an increasing function of the distance between it and the inlet via which the particles are fed into the dense fluidized bed.
