These all seem about right. We run our Turbine on constant pressure control. With 3 1350psi boiler in front of it. inlet pressure to the turbine stays constant. As the coal fired boiler push or lag, the turbine inlet control valves open or close to keep pressure at setpoint, this will increase or decrease the turbine load. MW will increase or decrease depending on inlet valve position. This makes for better boiler controls, but not constant turbine loading. When we take our unit out of pressure control the load on the turbine is constant, the inlet control valves do not move. but the 1350psi header will swing or sag with boiler loading.
