Free mounted packing for rotary regenerative heat exchanger

摘要

The gas flow bypass around the heating elements in a regenerative air preheater is reduced by the use of floating bypass seals which are placed in the rotor compartments between stacked heating elements. The seals comprise a frame with an open center with the peripheral frame portion bridging the gaps between the heating elements and the sides of the compartments. The seals may be adjustable and may include a deformable edge seal to actually contact and seal against the sides.
