Abstract

A pre-mixing combustion chamber (8) for a gas turbine is disclosed which includes a main stage with at least one pre-mixing chamber and a combustion chamber fashioned at least partly dynamically balanced relative to its longitudinal axis with a main combustion zone (3) and an after-combustion zone (5) placed downstream, whereby the at least one pre-mixing chamber discharges into the combustion chamber in the region of the main combustion zone tangentially producing twisting action. The pre-mixing chamber also includes a pilot stage (4) with a pilot injection means, whereby the main combustion zone in the combustion chamber proceeds essentially coaxial to the after-combustion zone, and the pilot stage is arranged at that end of the combustion chamber remote from the after-combustion zone.
