Abstract:

A system is configured to process steam. The system includes a steam supply line, a corrugator system, a heat sink, and one or more return lines. The corrugator system includes two corrugating rolls. The corrugating rolls each have a plurality of bores formed therethrough. The bores extend substantially longitudinally through the corrugating rolls. The heat sink is configured to draw steam through the corrugator system. The one or more return lines are in fluid communication with one or both of the corrugator system or the heat sink. The one or more return lines are configured to receive condensate communicated from one or both of the corrugator system or the heat sink. A steam trap assembly may also be positioned between the heat sink and a return line. The steam trap assembly may include a steam trap and a bypass line that is operable to selectively bypass the steam trap.
