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

What are and why Steam Traps? The duty of a steam trap is to discharge condensate, air and other incondensable gases from a steam system while not permitting the escape of live steam. The steam trap is an essential part of any steam system.
To meet the clean steam criteria, the steam trap should be made from clean steam grade material and manufactured keeping in mind the various criteria like surface finish etc. 7. Maximum Pressure and temperature While selecting a steam trap, one has to consider the maximum pressure to which the steam trap will be operated.
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 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
The Steam System Survey Guide has been developed at the request of the U.S. Department of Energy’s Office of Industrial Technologies. The author wishes to thank Tony Wright of the U.S. Department of Energy BestPractices Steam Program for his support and many reviews of this document.

Steam Traps A type of automatic valve that filters out condensate from steam and non-condensable gases such as air without letting steam escape. Most steam traps will also pass non-condensable gases while remaining tight to live steam. Un-drained condensate at PRV stations will back up into the steam line and will cause steam cutting on.

Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler’s net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
