Yes, in the system the grid frequency is given as input. In The ST inlet valve positioning together with changing the firing rate takes place thus the fuel consumption rises. Are there any other mechanisms of PFC which does not effect fuel consump. rate?Does it help to damp steam extraction...
Can you clarify your ST configuration. You mentioned a GT, an HP turbine and an LP turbine. (When you say HP and LP, I refer to ST.) And I understand that you use process steam in ST.(no HRSG). Right?
GTs are equipped with barring or turning gear devices in order to avoid rotor distortion after gt is shut down. The turning gear engages at a predetermined rotational speed and rotates the shaft at a constant low rpm until the turbine metal temperature falls to a certain temperature at which...
