Abstract
The connecting plate duct assemblies which form the inlet and outlet ducts for a rotary regenerative air preheater have a horizontal flange plate around the periphery. The vertical panels which house the rotor sit on the lower horizontal flange plate and are attached to lower vertical attachment bars extending up from the lower horizontal flange plate. The upper ends of the vertical housing panels are spaced below the upper horizontal flange plate and abut upper vertical attachment bars extending down from the upper horizontal flange plate. The upper ends of the vertical housing panels are welded to these upper vertical attachment bars to hold them in position and to seal the space. Sealing means are provided between the vertical housing panels and the rotor at both the upper and lower ends.
