摘要： 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).

摘要： Rotary flows are generated in a variety of technical installations.In these uses, the particular properties of the rotary flows generated and consequently those of the swirl generator itself play an essential part. Thus, for example in burner construction, a swirl is imparted to the combustion air, in order, on the one hand, to accelerate mixing between the fuel and air and, on the other hand, to utilize a possible return flow to improve the ignition condition.One question, among others relating to the design of the swirl generator, is to decide which flames with which properties are produced by the burner.It is therefore desirable, for control and optimization of the flame properties, to have available a swirl body of variable swirl intensity and swirl distribution.For this purpose, the swirl body (1) is equipped with several exchangeable guide blades (4) which are pushed in through a slotted outer tube (2) radially and at a pitch angle (.theta.). A likewise slotted inner tube (3) performs the function of fixing the guide blades (4) internally.
