Steam Traps |

The steam trap is designed to close in the presence of steam and drain the condensate. As the steam condenses into a liquid, it gives up its latent heat. The latent heat results in lb, for lb the steam releasing more energy than the water. The steam traps purpose is to prevent the steam leaving the system before it gives up its latent energy

Fixing Water Condensate Problems - Maintaining Steam Traps

Bad traps can be the major cause of water hammer problems, and steam in the condensate lines can cause overheating in your building. Supers often increase the steam pressure to make up for the losses in system pressurization from having bad steam traps. Increased steam pressure can be the cause of pipe knocking in the system.

Steam Traps Affect Boiler Plant Efficiency

steam trap population allows condensate to be removed from the steam system effectively which means it can be re-used. We call this ‘condensate recovery’ and it saves energy and cost in a number of different ways: Condensate returned to the feedtank reduces the need for boiler blowdown, which is used to reduce the concentration of
