A dense fluidized bed exchanger includes a casing the vertical longitudinal walls of which consist of tubes conveying a heat-conducting fluid, the casing being divided lengthwise into chambers separated from each other by a baffle consisting of a wall consisting of tubes conveying a heat-conducting fluid. The vertical longitudinal walls consist of horizontal tubes and the baffle extends from the bottom wall of the casing to a height less than that of the latter and consists of superposed hairpin-shape transverse extensions of tubes of each of the vertical longitudinal walls disposed perpendicular to the tubes and extending to the opposite vertical longitudinal wall.

Dense fluidized bed exchanger to be associated with a circulating

The present invention relates to a hot gas recovery boiler comprising a substantially horizontal gas inlet duct, a gas deflection duct connected to the inlet duct and opening out into a generally vertical enclosure that contains a set of superposed and substantially horizontal heat exchange stages plus a flue gas exhaust duct at the top of the enclosure. At least one heat exchanger is disposed in the proximity of the outlet of said inlet duct.
