Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! A back pressure in a condensate systems will reduce steam trap capacity
Steam trap capacities are reduced if there is a back pressure in the condensate system. A back pressure can be the result of excessive
flash steam generation.
Back pressure and reduction in steam trap capacities:
