Hi Users,
We have a 20MW GE's gas turbine. It's a 2 stage turbine.
We have 8 wheelspace thermocouples installed on the machine.
1FO2
1FO3
1AO2
1AO3
2FO2
2FO3
2AO1
2AO2
If we take the turbine wheel and nozzle arrangement as
N1 1st Stage Nozzle
T1 (Turbine Stage 1 wheel)
N2 2nd Stage Nozzle
And T2 Turbine stage 2 wheel
Then, the wheelspaces would be between N1 T1, T1 N2, and N2 T2.
Corresponding to these the Wheelspace TCs would be in the arrangement as
N1 T1 1FO2 & 1FO3
T1 N2 1AO2 & 1AO3
N2 T2 2FO2 & 2FO3
And....
There is no wheelspace on T2 Aft outer. Still, the wheelspace TC nomenclature suggests so... Could anyone please explain where exactly 2AO1 and 2AO2 are installed.
Regards,
