INFRARED PIPELINE HEATER

摘要

A pipeline heater (20) for warming a fluid stream, such as a fluid being carried by a natural gas or petroleum pipeline includes a housing (22) having a plurality of IR heating elements (118) and coils (110) installed therein. Individual conduits (88, 90) direct the fluid stream into and out of the housing (22). Coils (110) direct portions of the fluid stream from the conduits (88, 90) past a plurality of IR heating elements (118).
