Dear all.

we have in our site 3 gas turbine 9FA and IBH one of them is opening at full load (temperature control) by 18% and IGV fully opened 84 degree. i checked IBH valve reference. i found its value like feed back 18%. i traced the IBH reference. i found its value coming from signal CSRDLNX (inlet bleed heating-extended DLN turndown), but i don't catch the reason. can any one help me why it is happened? and How to solve this problem?

thanks for all
