In 9fa machine, turbine 2nd & 3rd stage nozzles are cooled by air which is extracted from 9th & 13th of compressor. Approximately what will the amount of air used for this cooling. Normally, how much percentage/volume of air we can extract from compressor?
Main reason for asking this question is: In running 9fa machine, we have the arrangement like this but in new erecting machine we have the arrangement for cooling air optimisation/controlling with respect to TTRF1.
