Patent number: 11448393Abstract: Apparatus for a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication, with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is then imposed on one or more tube support plates, as the steam generator heats up. The tube support plate displacement system has only one part, a push rod, which is internal to the steam generator shroud, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, in the same or varying amounts and directions, and with one or more apparatus for each individual tube support plate.Type: GrantFiled: August 29, 2016Date of Patent: September 20, 2022Assignee: BWXT Canada Ltd.Inventors: Richard G. Klarner, Robert S. Horvath, Ghasem V. Asadi, Paul W. Shipp

Patent number: 9347662Abstract: An apparatus in a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is imposed on one or more tube support plates as the steam generator heats up. The tube support plate displacement system has only two parts, a spring bar and a push rod, that are internal to the steam generator shell and threadably engaged, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, with one or more apparatus being provided for any individual tube support plate.Type: GrantFiled: September 19, 2013Date of Patent: May 24, 2016Assignee: BWXT Canada Ltd.Inventors: Richard G Klarner, Robert S Horvath, Ghasem V Asadi, Thomas Waring

The tube support plates are aligned during fabrication, with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is then imposed on one or more tube support plates, as the steam generator heats up. Displacement to produce misalignment is produced only when the steam generator is heated. The tube support plate displacement system has only one part, a push rod, which is internal to the steam generator shroud, thereby minimizing the potential of loose parts.Type: GrantFiled: July 25, 2008Date of Patent: November 5, 2013Assignee: Babcock & Wilcox Canada Ltd.Inventors: Richard G.

Publication number: 20100276550Abstract: A tube support plate with an offset pattern of tube receiving holes formed therein, the pattern being offset from either the X or Y axis of the tube support plate. One half of the offset pattern of tube receiving holes is on one side of the selected axis and the other half is on the other side of the selected axis. The offset pattern of tube receiving holes is the result of an increased pitch between pattern halves at the selected axis.Type: ApplicationFiled: April 29, 2009Publication date: November 4, 2010Inventors: Richard G.
