Paper Abstract

Dynamic monitoring of steam trap and steam coil surface thermal patterns can indicate steam system malfunction. Condensate lines at atmospheric pressure showed a temperature fluctuation of several degrees due to a momentary pressure increase caused by a properly functioning steam trap cycling. A malfunctioning trap showed no such increase. This effect decreases with increased condensate line pressure. Steady state observation of the tempera-ture drop across steam traps could not reliably distinguish good traps from bad. Dynamic observation of steam coil surface temperatures showed a typical 10% to 15% loss of heating surface due to gas blockage. Purging by installing an air vent provides only temporary relief.
