Hi,
When giving shutdown command to HRSG, the sequence is that bypass damper to open fully in 80 sec. then inlet damper to fully close in another 80 sec. In our case, if GTG load is high (i.e above 45 MW) the unit (GTG) trips on an external trip signal. GTG load should be reduced to safely shutdown the GTG.
I tried to link out the relation between power loads and modulating dampers but unfortunately failed.
Anybody has an idea in this regard.
