A gas turbine uses three components
The ambient air is drawn in by
compressor
the combustion chamber
the compressor
the turbine
turbine
A, generally centrifugal or axial, which brings it to a pressure included in modern machines between 10 and 30 bar approximately.
It then enters
compressor
the combustion chamber
the compressor
the turbine
turbine
B, in which a fuel injected under pressure is burned with the previously compressed air (the latter in great excess in order to limit the temperature of the burnt gases).
The gases at high temperature (1000-1200 ° C) are then expanded in
compressor
the combustion chamber
the compressor
the turbine
turbine
C, generally axial.
A significant part (60 to 70%) of the work recovered on the
compressor
the combustion chamber
the compressor
the turbine
turbine
shaft is used to drive the
compressor
the combustion chamber
the compressor
the turbine
