In ProII, how is saturated condensate defined using steam heating?
Thread Content
In the simulation in ProII for heating cold materials with medium-pressure steam (superheated), the specified temperature for the product flowing through the heat exchanger is 220°C. However, after introducing the steam flow, either steam or subcooled condensate emerges from the heat exchanger. Is there any effective control method to ensure that the condensate is saturated?
I usually specify the vapor-phase fraction at the outlet on the steam side; you can take that as a reference.
Controlling whether the gas fraction at the condensate outlet is 0 or supercooled condensate, rather than saturated condensate… It seems acceptable to define the temperature of the condensate as the temperature of saturated condensate, but it’s a bit complicated
Defining pressure and vaporization fraction is what corresponds to a saturated state.
The pressure has already been defined in the input steam
Set exit vapor frac. = 0
