15/11/2016 · The low-pressure steam extracted from the main turbine, generally between the high-pressure (HP) turbine and intermediate pressure (IP) turbine sections, will range from 75 psig to 250 psig. On the other hand, high-pressure steam directed from the boiler can reach pressures as high as 2400 psig, even 3500 psig in supercritical plants.

Low order boiler-turbine dynamic models and stress …

In this thesis low order dynamic models of the boiler-turbine system are developed and critical variables for boiler constraints, e g. throttle temperature and pressure are taken into account. Furthermore the turbine rotor metal dynamic model representing the thermal stresses at the rotor surface and bore is estimated since a direct measurement is not possible.
