We have F7EA with Mark Vie control. It is NON-DLN with HRSG. Due to market condition we would like to run IGV on temperature control so that steam production can be increased. We never tried before. I went through this forum using search engine, and found that once on base load IGV can not be control (remains full open). Here are the questions:
Can we use manual button on IGV page on HMI to close IGV, if yes how far load has to drop?
I think if controlling FSR is FSRT then IGV can not be controlled, controlling FSR should FSRN to close IGV?
Being a median select IGV can not be closed under 57 ( in 57 and max is 84).
If we bring it down what should we look CPD, MW or any other parameter?
I don't know what else could be look into it? I appreciate if CSA answers? Any member using IGV control or manipulating IGV for steam make on regular basis or occasionally? Please share your experience with forum.
Thanks
