Tadek Casimir Brzytwa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Air preheater heat transfer elements and method of manufacture
    Patent number: 5983985
    Abstract: Heat transfer elements for rotary regenerative heat exchangers are formed with spacing ridges or notches having flow-disrupting indentations in the peaks of the notches formed at selected intervals to project into the flow channels. These projections interrupt the boundary layer and cause turbulence and mixing to enhance the heat transfer. Various methods of forming the indentations are disclosed.
    Type: Grant
    Filed: May 5, 1999
    Date of Patent: November 16, 1999
    Assignee: ABB Air Preheater, Inc.
    Inventors: Wayne S. Counterman, Gary Foster Brown, Tadek Casimir Brzytwa, Michael Ming-Ming Chen, Scott Frederick Harting, James David Seebald

  • Air preheater heat transfer surface
    Patent number: 5899261
    Abstract: A heat exchange element for an air preheater has first and second heat transfer elements arranged to form channels for the passage of a heat exchange media having a main flow direction. Each of the heat exchange plates has parallel straight ridges and flats between the ridges. The ridges alternate to extend transversely from opposite sides of each heat transfer plate. The ridges of the adjacent plates are oriented obliquely in opposite directions relative to the main flow direction and contact each other solely at points of intersection of the ridges.
