In the combustion space of a combustion chamber of a gas turbine operated with liquid fuel, at least one after-burner (4) is employed in each case in combination with one or more primary burners (2, 2a). The after-burner (4) and at least its fuel spray cone (15), which acts directly into the central combustion chamber (6), are screened by an unswirled enveloping airstream (14) against the hot gases (13) from the combustion in the primary burners (2, 2a). The after-burner (4) itself is not automatically operating, i.e. the ignition of its mixture (14/15) takes place further downstream, preferably at the beginning of the mixing chamber (7), as a result of which a turbulence-free flow with uniform pressure and temperature profile is provided for acting on the turbine (9).

A combustion chamber of a gas turbine for operation with liquid fuels, the combustion chamber comprising: a main combustion space defined within the combustion chamber and having an upstream end and a downstream end; a secondary burner centrally positioned at the upstream end of the main combustion space and including fuel feed means for introducing a fuel mist into the main combustion space; two primary burners symmetrically positioned with respect to the secondary burner, each of the primary burners including a primary combustion space which is positioned upstream of the secondary burner with respect to the main combustion space; and air supply means for supplying an unswirled stream of air enveloping the fuel mist as the fuel mist enters the main combustion space to protect the fuel mist from direct exposure to hot gases leaving the primary combustion space when the fuel mist is first introduced into the main combustion space.
