ABSTRACT:
The heat exchanger comprises at least one first sheet tubes and at least one second sheet of tubes, the sheets being suspended in a case. The two sheets are juxtaposed in a vertical plane, the first sheet of tubes connecting a first inlet fluid manifold disposed at the bottom and on one side of a case to an outlet manifold disposed in a central top portion of the case, and the second sheet of tubes connecting a second inlet fluid manifold disposed at the bottom and on one side of the case to the outlet manifold. Each sheet comprises first tubes which extend horizontally in the bottom portion of the case, second tubes which are connected to the first tubes and which extend vertically between the bottom portion of the case and the middle portion of the case, and bent third tubes which are connected to the second tubes and which extend between the middle portion of the case and the top portion of the case. This configuration makes it possible to obtain a large heat exchange area with a compact heat exchanger. The heat exchanger is designed to be installed in an external dense bed equipping a circulating fluidized bed hearth.
