Efficient and reliable operation is always an objective of a steam system owner or operator. If your system employs heat exchangers, an understanding of heat exchanger stall will put you on a path to efficient operation, lower maintenance, and possibly longer useful life for major parts of your system.
Heat exchanger stall occurs when low load conditions reduce the steam pressure in the heat exchanger, decreasing the pressure differential across the steam trap to a point below the back pressure in the condensate line. The resulting condition causes condensate to back up into the heat exchanger, reducing its efficiency. There are other negative effects that are illustrated in the animated video below, produced by world recognized steam system experts Spirax Sarco and presented by MSEC a distributor in the Western US.
The video is useful and comprehensible to a wide range of skill and knowledge levels. It takes only four minutes to view, and will leave you with a better understanding of how you can get consistent and efficient performance from your steam system.
