The turbine extracts steam at 1.0 Mpa, which is the same as the steam pressure at the turbine’s back pressure, also 1.0 Mpa

Dear sea friends, as the title suggests, what are the advantages and disadvantages of the two steam generation approaches in terms of turbine selection? Suddenly, this question came to mind: personally, I think there isn’t much difference, right? I majored in instrumentation and work frequently with compressor control, so I would like to ask for your feedback if there are any mistakes in what I say; discussions from everyone are welcome.
For the two steam-output options at 1.0 MPa alone, the difference is indeed minimal; however, the choice between a extraction-condensing turbine or a back-pressure turbine depends on the requirements of the installation: turbine speed, steam pressure, flow rate, available installation space, the purpose of the condensate, and so on.
