Abstract: A seal assembly for a regenerative heat exchanger can include a primary sealing member with a mounting base and a flexible contact portion that defines a first distance between a proximal edge of the mounting base and a contact edge of the flexible contact portion, the first distance being generally constant along the length of the primary sealing member. The seal assembly can also include a second member with a mounting portion and a cantilevered portion that defines a second distance between a proximal edge of the mounting portion and a distal edge of the cantilevered portion, the second distance being generally constant along the length of the second member. The first distance is greater than the second distance by a predetermined amount so as to limit the preload flexure of the flexible contact portion against a sector plate of the heat exchanger when the seal assembly is installed in the regenerative heat exchanger.

Abstract: Powder coated heat exchange elements for a heat exchanger. Powder coating provides improved protective coating on surfaces of heat exchange elements. In many applications, the heat exchange elements are subjected to harsh operating conditions that promote corrosion. Traditional enamel coating tends to fracture when subjected to mechanical stresses thereby allowing corrosion inducing agents to penetrate and corrode the underlying surfaces. Powder coating reduces breaches in the protective layer. Powder coating may be adapted to withstand high temperatures so as to make them suitable for use in harsh operating environments. One such environment can be found in the processing of flue gas from fossil burning power generators, where the flue gas has a relatively high temperature and high sulfur content.

Abstract: A seal assembly for a regenerative heat exchanger can include a sealing member with a mounting base and a flexible contact portion having a contact edge that resiliently contacts a sector plate of the heat exchanger housing when the seal assembly is mounted to the heat exchanger. The seal assembly can also include a curvilinear support with a mounting section and a curved extended portion attached to the mounting section and having a predetermined curvature that gradually contacts the flexible contact portion as flexion of the flexible contact portion is increased, thereby gradually moving a flex point of the flexible contact portion toward the contact edge of the curvilinear support and gradually increasing a spring constant of the unsupported end of the flexible contact portion to resist further flexion of the flexible contact portion.
