    摘要: A combustion chamber of a combustion system has a combustion space, a support structure, a support element, and a heat shield. The heat shield has at least two segments, and each segment includes a liner element facing the combustion space and has an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, and a retaining device. The retaining device fixes the respective liner element on the support structure via the support element and forms a flange region that fits over the edge region of the respective liner element. The retaining device forms a first cooling passage with the support element and has at least one through-opening in the flange region. A cooling gas flows through the through.opening from the first cooling passage to the edge region.

    摘要: A premix burner, for example for a gas turbine, having a conical swirl generator (1) and a cylindrical mixing section (2) which follows it in the direction of flow, includes a high-pressure atomizer nozzle (10) with one or more fuel feed passages. The high-pressure atomizer nozzle (10) includes at least two outlet passages, through which liquid fuel enters the swirl generator (1), these passages being arranged off-center with respect to the longitudinal axis of the nozzle and being configured in such a way that the spray cone (11) of the fuel is oriented at an angle (β) with respect to the longitudinal axis of the swirl generator (1) which is smaller than the cone half-angle (α) of the swirl generator (1). The outlet passages in particular have an internal geometry with a conically narrowed section.

    摘要: In a method for reducing the NOx emissions from a burner arrangement comprising a plurality of burners (B1, . . . , Bn), in particular in a gas turbine, which burners (B1, . . . , Bn) are operated in parallel and each burner supplied fuel by means of combustion air to form a flame (F1, . . . , Fn), an effective drop is achieved in a simple way by virtue of the fact that at a predetermined time the flame temperatures of individual burners (B1, . . . , Bn) or burner groups or differences between the flame temperatures of individual burners (B1, . . . , Bn) or burner groups are measured directly or indirectly. The fuel supply to those burners or burner groups whose flame temperature exceeds a predetermined value for the flame temperature is selectively throttled in order to homogenize the flame temperatures of the burners (B1, . . . , Bn).

    摘要: A premix burner consisting essentially of a swirl generator for a combustion air stream or another gaseous oxidizing medium and of conduits for injecting fuel into the swirl flow thus generated. As a result of a discontinuous cross-sectional widening at the transition to the combustion space, the swirl flow bursts open and a backflow bubble is formed, which serves for flame stabilization. For use under extreme thermal conditions, the burner front is provided with a heat shield which is fastened to a carrier structure in such a way as to allow, as unimpeded as possible, differential thermal expansions. The carrier structure is preferably provided with orifices, through which cooling air for the impact cooling of the heat shield flows. In a preferred variant, the fuel gas supply is designed as pipes which are led through orifices of the swirl generator without any fixed connection. As a result of this design, thermal stresses in the material of the burner are avoided as far as possible.
