Abstract
A rotary regenerative air preheater has pinrack seals including a U-seal located between the upper and lower pinrack rails and a trough-shaped filler-seal located between the upper and lower pinrack supports of adjacent pinrack assemblies. The inboard edges of the wing portions of the filler seal are welded to the rotor shell, the outboard edge of each leg portion of the U-seal engages a pin in one of the adjacent pinrack assemblies, and the upper and lower edges of the U-seal and the filler-seal engage the upper and lower pinrack rails and the upper and lower pinrack supports, respectively, to seal the pinrack assemblies to the rotor shell.
