ABSTRACT:
A heat exchange apparatus (10) formed of a plurality of heat exchange modules (20) mounted together in side-by-side relationship to form a box-like array. Each heat exchange module (20) houses a multiplicity of heat exchange tubes (44) which provide a flow passage through which a first heat exchange fluid, such as air, is passed in heat exchange relationship with a second heat exchange fluid, such as flue gas, passing through the heat exchange apparatus over the heat exchange tubes. Each heat exchange module (20) is comprised of a rectangular box-like support frame (30) formed of a pair of spaced apart end frames (32a,32b) interconnected at their respective corners by longitudinally elongated support members (34a,34b), a tube bundle assembly (40) disposed within the support frame, and attachment means (50,50') for mounting the tube bundle assembly to the support frame, the attachment means (50') including expansion means (52) for accommodating translational movement of at least one tube sheet (42a) of the tube bundle assembly within the support frame as the heat exchange tubes of the tube bundle assembly expand or contract longitudinally.
