Patent number: 8721278Abstract: A flange connection for an exhaust section of a gas turbine engine. The flange connection includes a stub flange attached to an exhaust manifold. The stub flange has a first axial face for engagement with the axial face of a cylinder flange extending radially from an exhaust cylinder. A plate structure attached to the cylinder flange is configured to provide axial retention of the stub flange to the axial face of the cylinder flange. The plate structure includes a resilient beam portion extending radially inwardly and engaging a second axial face of the stub flange. The stub flange is retained between the cylinder flange and the beam portion of the plate structure in an interference fit to provide three degrees of freedom of the stub flange relative to the exhaust cylinder.Type: GrantFiled: March 11, 2011Date of Patent: May 13, 2014Assignee: Siemens Energy, Inc.Inventors: Yevgeniy Shteyman, James Marshall, Brian Micklos, Jonathan Leagon, Christopher Scogin, Brian H.

Patent number: 7082380Abstract: A refrigeration monitor and methodology are capable of detecting and recording data from selected sensors associated with monitored refrigeration equipment. The data are sampled periodically and stored as time series. Reference data are established and stored for normal operation of the system. Software operating on the data acts in real-time to detect fault conditions by comparing recent historic data with reference data. Upon detection of a fault, a technician is notified by a pager. Software used by the technician supports the monitoring in real-time of the operation of the refrigeration equipment and a review of the equipment's historical performance. The technician can access the monitor either by making a connection on-site or remotely over a communications network such as the Internet.Type: GrantFiled: November 21, 2003Date of Patent: July 25, 2006Inventors: David Wiebe, Phillip Smith, Lawrence Johnson

Publication number: 20050066647Abstract: A turbine engine exhaust diffuser assembly having a tuneable exhaust velocity profile is disclosed. The assembly includes structure that generates a desired, tunable velocity profile within working fluid exiting the exhaust diffuser assembly. The exhaust assembly includes an concentric boundary sleeves that extend along a central axis and form an exhaust flowpath between them. A flow deflecting member disposed within the flowpath longitudinally divides the flowpath into a first region and a second region. The first region is characterized by a first predetermined velocity profile, and the second region is characterized by a second predetermined velocity profile. The second velocity profile is determined by at least one pre-selected dimension of the flow deflecting member. Methods of maximizing HRSG energy extraction capacity and extending HRSG lifespan are also disclosed.Type: ApplicationFiled: September 25, 2003Publication date: March 31, 2005Inventors: David Wiebe, Eric Berrong
