摘要： A bypass seal (56) for a rotary regenerative air preheater includes primary and secondary seal leaves (58, 60) that are joined at a single position longitudinally intermediate their first and second sends. The first end portion (90) of the primary seal leaf (58) extends longitudinally beyond the first end (92) of the secondary seal leaf (60) and the second end portion of the secondary seal leaf (60) extends longitudinally beyond the second end of the primary seal leaf (58). When installed in the air preheater, the first end portion of the primary seal leaf (58) of each bypass seal (56) in one of the seal rings overlaps the second end portion of the secondary seal leaf (60) of an adjacent bypass seal in the seal ring.

摘要： A heat transfer element basket assembly (36) for a rotary regenerative heat exchanger (10) having a basket framework including oppositely disposed first and second side shells (76), means for holding the side shells in a spaced relationship, and heat absorbent material is disposed within the framework. The inboard end portions (88) of first and second substantially planar flange plates (84) are mounted to the outboard end portions of the first and second side shells (76), respectively. The outboard end portions (92) of the first and second flange plates (84) are each mounted to an adjacent diaphragm plate (34) to install the basket asembly (36) in the heat exchanger rotor (14). The first and second side shells (76) of the basket assemblies define an angle therebetween which is substantially equal to the angle of the diaphragm plates (34).

摘要： A method for constructing a rotor (14) of an air preheater (10) having a plurality of diaphragm plates (32) dividing the rotor (14) into a number of wedge-shaped compartments (30). Each compartment (30) includes compartment components such as a rotor shell plate (38), a hot end rotor angle (40), a cold end rotor angle (42), and one or more stay plates (44) and means for locating at least a portion of each of the components within the compartment. The diaphragm plates (32) comprise at least one opening serving as an index location associated with each compartment component on each diaphragm plate blank. Each compartment (30) is assembled by positioning a first diaphragm plate (32) adjacent to a second diaphragm plate (32) and locating each compartment component between the adjacent diaphragm plates (32) by engaging the locating means of the component in an associated opening in one of the diaphragm plates (32).

摘要： A method for adding additional axial seals and radial seals within existing air preheaters. The installed heat transfer baskets, radial seals, axial seals, and gratings are all removed from the air preheater. The existing stay plates are modified, if they are to be reused, or replaced with new stay plates. An intermediate diaphragm plate is positioned in each original compartment and mounted to the stay plates. Additional hot and cold end axial seal support bars are mounted to the rotor shell and intermediate diaphragm plate. Axial seals are installed on the original and additional axial seal support bars and radial seals are installed on the axial edges of the original and intermediate diaphragm plates. Finally, new heat transfer baskets are inserted into each of the compartments formed by the original diaphragm plates, the intermediate diaphragm plates, and the rotor shell.
