An axial seal plate for an air preheater having a single, unitary structure including a sealing portion disposed intermediate first and second end portions extending orthogonally from the sealing portion. The axial seal plate does not including any welds for joining the end portions to the sealing portion.

Low-distortion axial seal plate for air preheaters

A sector plate for an air preheater including a seal plate having a sealing surface and an oppositely disposed mounting surface. Multiple tabs mount a portion of a rigid support structure to the mounting surface of the seal plate. Multiple support members mount the support structure to the air preheater.

Low-distortion sector plate for air preheaters

A transition element for providing an interface between a duct having a substantially rectangular cross section and an air preheater having a substantially circular cross section. The transition element includes an inner sidewall, an outer sidewall, and first and second end walls, where the outer sidewall and the first and second end walls form first and second transition corners. Each of the transition corners comprises first and second flow deflectors, each having an outer terminal edge and first and second side edges extending laterally from the terminal edge to an inner point. The first side edge of the first flow deflector is mounted to the second side edge of the second flow deflector and the outer terminal edges of the first and second flow deflectors are mounted to the duct to connect the air preheater to the duct.

Single seam duct corner

A rotary regenerative air preheater has ring assemblies at the upper and lower ends which define the outer periphery and support the air preheater housing panels. The ring assemblies are spaced by spokes which are tied to the hub of the air preheater and vertically supported from the air preheater structural members. The rotor housing panels are attached around and between the spoked ring assemblies. The ring assemblies are formed form a series of uniform interchangeable segments and they support the peripheral bypass seals.
