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 heater casing internal section that is insertable from the external surface of the heater through a hole in the casing into an interior of the heater and a heater casing external section that includes an external shoulder that remains outside of the hole in the heater casing.
A radiant tube coil support system for fired heaters comprising:
- at least one tube support that includes a heater casing internal section that is insertable from the external surface of the heater and a heater casing 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 heater casing internal section that is insertable from the external surface of the heater and a heater casing 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 the radiant tube and control movement of the radiant tube.
