Information

The steam trap ensures that only liquid condensate leaves the component, while any flashed steam is returned to a liquid state before discharge. The model assumes a steady state isenthalpic thermodynamic process that transforms water from an upstream high pressure state to atmospheric pressure, followed by an isobaric condensation process as flashed steam vapor is returned to a liquid state. This implementation is consistent with physical valves that vent to the atmosphere.
