Abstract (en)
[origin: EP0536962A1] A heat exchanger has a duct (11) through which heated gases pass. A plurality of tube panels (14) are within the duct and each panel includes a header (18) from which a plurality of tubes extend. A pair of hangers (30) support each tube panel to form space in the duct above and below the tube panel for maintenance access. Baffles (41,42) restrict the flow of gases through these spaces. Each hanger has a bracket (28) attached to the header of the tube panel with a rod (32) pivotally coupled to the bracket and extending through an aperture in the roof of the duct. The hangers are connected to structural members on the exterior of the duct in a manner that maintains the tube panel in a fixed position during operation of the heat exchanger, while allowing movement of a panel within said duct for maintenance. A jack (50) is also provided to raise and lower a panel (14). <IMAGE>
