Radiant tube heaters are installed in many open warehouse and service applications. The heater consists of a fuel gas burner at one end and a tube that passes through an exterior wall at the opposite end. Hot exhaust gases from the burner heat the tube, which radiates the heat in the surrounding space. Several gas explosions had occurred in building with these heaters; the gas explosions were accompanied by fatigue fracture of a copper gas supply tube at the connection to the burner control. Failure analysis investigations of radiant tube heaters involved in explosions were instrumental to a proposed, and subsequently approved, revision to the National Fuel Gas Code (NFPA 54) that changed the requirements for installation of these heaters. These changes demonstrate the potential impact of the failure analysis process to prevent future failures.
