  • Patent number: 11248478
    Abstract: An exhaust apparatus for a gas turbine includes an annular duct with struts extending from an outer duct-wall to an inner duct-wall of the annular duct. Each strut is encapsulated in a respective strut shield. An interface of the strut shield with a respective duct-wall includes a collar extending along a partial length of the perimeter of the strut shield at the respective interface. The collar includes a first section extending radially and aligned with the strut shield, and a second section oriented at an angle to the first section and aligned with the respective duct-wall. The first section is attached to the strut shield along a first joint and the second section is attached to the respective duct-wall along a second joint. An intersection of the first and second sections is formed by a smooth curve defined by a radius configured to distribute stresses at the respective interface.

  • Patent number: 10649866
    Abstract: A method and system permit a backup entity of a redundant apparatus of a communication system that shares control of hardware resources or other network resources with an active entity to indirectly determine a status of the active entity based upon behavior and reaction to actions it takes in connection with resources it shares control of with the active entity. Such a method and system permit the backup entity to deduce the state of the active entity without having any a hardware connection or other communication connection with the active entity.

  • Patent number: 9115911
    Abstract: A direct-fired heater suitable for connection to duct work is provided. The heater comprises a combustion chamber defined by a combustion chamber wall, a burner plate at one end proximate a fan blade and an exhaust plate at an opposite end, the burner plate having openings therein for allowing airflow into the combustion chamber and the exhaust plate have an opening therein for allowing exit of heated exhaust from the combustion chamber, the combustion chamber wall extending past the burner plate. A first airflow zone exists between the outer shell and the combustion chamber allowing airflow between the fan blade and the outlet in the outer shell. An injector for injecting gas into the combustion chamber in proximity to the openings in the burner plate is used.

  • Patent number: 8721278
    Abstract: 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.

  • Patent number: 7082380
    Abstract: 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.

  • Publication number: 20050066647
    Abstract: 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.
