With 100 t of condensate at 0.6 MPa, what pressure of steam can be obtained through flash evaporation?
Thread Content
By extension, for steam condensate under a given pressure, is the steam pressure obtained through flashing predetermined, or is there some theoretical basis for it?
It should be the condensate at a given temperature, and then the pressure of the condensate after flashing is specified.
The pressure of the resulting flash vapor is lower than that of the condensate; the amount of vapor that can be obtained depends on the pressure of the flash vapor
Then the pressure resulting from flashing (which is, of course, lower than the condensate pressure) is the specified value, right? But I once heard an experienced person say that it’s to consume all of the kinetic energy of the condensate. According to the veterans, it’s a matter of calculation; there is a theoretical basis for it, rather than it being something that is specified arbitrarily.
Steam with a pressure below 0.6 MPa should be able to generate it； The lower the pressure, the greater the amount of steam, but it is not possible for all of the condensate to turn into steam.
It must be specified; the amount of steam produced varies depending on the flash pressure. One set of equations is enough: conservation of mass and conservation of energy, two equations in total
