Dear all
We have a 9FA dual GT with DLN 2.6+, mark VI by
the readings in this valuable forum I already know that one of the main function of IBH is to protect the axial compressor from surge conditions (we also have some valves to avoid that surge conditions 20CB-1, 20CB-2, wich discharg from extraction 9 and 13 to the exhaust) and to extend the premix combustion mode (we have mode 3-6.2-6.3 or mode N-B-C) and that way to achieve the low NOX emision in a wide range of load.
the compressor need the IBH and the 20CB valves?? is not enough with de IBH (in the former DLN the IBH never was used at all)
I also know that the changes of combution modes are given by the CA_CRT factor (before this was done with the TTRF1)
what is exactly the CA_CRT? why use that and not the TTRF?
but my main question is ...with liquid fuel the behaivor of the IBH is complete different to in natural gas but the changes in combustion modes are given in the same CA_CRT , and the reduction in nox emission is because the water inyection so wich is the function of IBH with liquid fuel? its also extend the combustion mode? in liquid or gas the combustion modes are the same?
