Question: What is the proportion of all steam extracted by the turbines in a waste-to-energy power plant relative to the total amount of steam used?

As the title suggests: In a waste-to-energy power plant, what is the proportion of all turbine extraction steam relative to the total steam volume? Those in charge of operations or those who are well-informed, please answer. Thank you so much!
There is also the issue of turbine parameters; compared to coal-fired power plants, the steam supply parameters for waste-to-energy plants should be relatively lower, right? What are those parameters usually? You need to know the parameters to determine the capacity
In the case of condensing units, the total amount of exhaust steam accounts for approximately 20% of the total steam volume.
Currently, the standard values are 4.0 MPa and 400°C, but there is now a trend toward higher parameters; some projects are starting to use values of 6.5 MPa and 450°C.
6.5 MPa and 450°C – that’s way too low! This parameter is already quite high; high-temperature corrosion of the heated surfaces will be severe, and cladding may be necessary, which is very costly
