US Patent 12007123 System for controlling thermal expansion in a tube heater

There is provided a system for securing a tube heater to a structure, the tube heater having a burner and a radiant tube extending to an exhaust outlet. The system includes an elongate canopy with an exhaust end securable to the exhaust outlet, an opposed burner end securable adjacent to the burner, and a reflector extending there between. An exhaust hanger is rigidly coupled to the structure and to the canopy proximate the exhaust end, and rigidly receives the exhaust outlet. A burner hanger is coupled to the canopy proximate the burner end and is slidably coupled to the structure. The burner hanger receives the radiant tube therethrough. The burner hanger allows the burner and burner end of the canopy to slide relative to the structure to accommodate thermal expansion of the radiant tube and the canopy from the exhaust end towards the burner end.
