<p>The exchanger is placed in a fluid of elevated temperature and comprises tubes connected to an inlet header and to an outlet header. The exchanger comprises a plurality of panels (4) constituted by tubes (41 to 48) extending below two inlet headers and two outlet headers, to which they are connected at the upstream and downstream ends, and forming two semi-panels which are imbricated one inside the other, each semi-panel comprising a subheader tube (41 or 42) connected to an inlet header (21 or 22) and being divided into at least one tube (43,44,45 or 46, 47, 48) which is coiled into a laced configuration so that the two sub-header tubes (41 or 42) extend vertically within the envelope of said tubes having a laced configuration and they support them through cantilever supports (411, 421). This exchanger may be in particular employed in a fluidized bed apparatus or for the recovery of the heat of gas or fumes.</p> |
