Air for combustion
 

Hello everyone,im modelling combustion in a can-combustor in a gas turbine.
and i need to know, one aprroximate % of the discharge-air of the compressor go to a combustion chamber?, because, the discharge-air of the compressor serves for auxiliary elements( refrigeration of blades,metals,etc..), and the rest of the % of the air, its used in a combustion chamber.


can anyone give an aproximate a genarally % of this mas flow rate?

pd: Turbine:hitachi ge frame 5, 5001N, year: 1974, power: 24MW

thanks very much
