OSTI ID:5898792
This patent describes a tube support grid for supporting and spacing heat exchanger tubes within a heat exchanger. The heat exchanger is characterized by expected temperature ranges according to location within the heat exchanger. Each heat exchange tube has both a coolant inlet and a coolant outlet adjacent to its base and is welded at the base to a tube sheet and extends generally upward therefrom. The heat exchanger has a predetermined location a predetermined distance above the tube sheet for the tube support grid. The tubes are arranged on a circular array with a predetermined number of circular rows. The bases of the tubes are arranged in a similar array, the radial and circumferential pitches vary within known limits according to the temperature of the tube sheet.
