Claims15
A radiant tube coil support system for fired heaters comprising:
- a support mounting frame adapted to be mounted on an external surface of a heater casing, and
- at least one tube support that is mounted to the support mounting frame, wherein the tube support includes a tube support internal section that is insertable from the external surface of the heater through a hole in the heater casing into an interior of the heater and a tube support external section that includes an external shoulder that remains outside of the hole in the heater casing, wherein each tube support comprises one or more voids that are in gaseous communication via vents to an exterior monitoring access plate for each tube support on exterior of the heater casing whereby monitoring of a status of each tube support is obtainable during operation of the fired heater.
A radiant tube coil support system for fired heaters comprising:
- at least one tube support that includes a tube support internal section that is insertable through a heater casing from an exterior of the fired heater into an interior of the fired heater and a tube support external section that includes an external shoulder that remains outside of the heater casing;
- at least one tube keeper for each tube support, each tube keeper including a tube keeper internal section that is insertable through the heater casing from the exterior of the fired heater into the interior of the fired heater and a tube keeper external section that includes an external shoulder that remains outside of the heater casing, wherein the tube keeper is adapted and dimensioned for placement over an upward surface of the tube support such that the tube keeper together with the tube support surround over one-half of an outer circumference of a radiant tube disposed along an interior wall of the fired heater and control movement of the radiant tube,
- wherein each tube support and tube keeper comprises one or more voids that are in gaseous communication via vents to an exterior monitoring access plate for each tube support and tube keeper on an exterior of the heater casing whereby monitoring of a status of individual tube supports is obtainable during operation of the fired heater.
