About 20 -40 bars above the static pressure inside the combustor

Mohammed Mohammed Said

Daljit,

It is 20 bar as it is found in the attached file.

Thanks

Best regards

Mohamed

Fuel injection pressure independent of the load and the turbine nozzle design.

Typically, at partial load, the injection pressure exceeds the pressure in the combustion chamber 10 ... 15 bar.

At full load injection pressure higher than the pressure in the combustion chamber 20 ... 30 bar.
