A basket for an air preheater includes two metallic frames each having two corner pieces and two connector pieces. For each frame, one of the connector pieces is secured to one end of each of the corner pieces and another of the connector pieces is secured to an opposite end of each of the corner pieces thereby forming a rectangular opening in each frame. The basket includes two heavy gauge metallic sheets that are secured to the corner pieces, thereby spacing the frames equally apart from and parallel to one another thereby forming a channel between two of the sheets.

Basket for heat transfer elements for a rotary air preheater

Heat transfer sheets () for a rotary regenerative heat exchanger () have a alternating first and second undulation surfaces (). The first and second undulation surfaces () are composed of parallel ridges () angled in alternating directions. When the heat transfer sheets () are stacked, they create passageways () between them that direct air/gas through them. The ridges () redirect the air flow near the surface of the heat transfer sheet () imparting turbulence reducing laminar flow to improve heat transfer. The heat transfer sheets () employ curved ridges () having valleys () between them that define passageways () that constantly redirect the air/gas flow minimizing turbulence, creating efficient heat transfer.

Heating element undulation patterns

A heat exchanger heat transfer element basket assembly () for receiving heat transfer element plates () therein. The heat exchanger heat transfer element basket assembly () includes first and second one-piece side straps (), a pair of inboard corner flanges (), an I-shaped splitter plate (), a pair of outboard corner flanges (), first and second end straps (), and a cap. Each of the first and second one-piece side straps () includes a center portion (), a first extension (), and a second extension (). Each of the first and second extensions () includes a flange portion that is folded over across the heat transfer element plates () so as to be operative to retain the heat transfer element plates () in the heat exchanger heat transfer element basket assembly ().
