    摘要: A fuel lance for spraying liquid and/or gaseous fuels into a combustion chamber, which fuel lance is provided with first means for the radial spraying of the liquid fuel from the liquid-fuel passage into the combustion chamber. The first means comprise a first guide tube, which, in the radial direction starting from the liquid-fuel passage, runs outward through a gas passage and an air passage. In addition, second means are provided, which comprise a second guide tube, which, in the radial direction starting from the gas passage, runs outward through the air passage and concentrically surrounds the first guide tube at a distance. Both guide tubes open in the region of a shell opening in the lance shell in such a way that the liquid-fuel jet discharging from the first guide tube discharges as a plain jet into the combustion chamber, and the fuel jets discharging from the guide tubes are surrounded in a sheath-like manner by the air flowing out of the air passage through the shell opening.

    摘要: An exemplary combustor includes at least a portion having an inner liner and an outer cover plate, which together form an interposed cooling chamber. A plurality of hollow elements extend from the liner and protrude into the cooling chamber. Each hollow element defines a damping volume connected to an inner volume of the combustion chamber via a calibrated duct. During operation, the hollow elements damp pressure pulsations and, in addition, also transfer heat.

    摘要: A fuel lance for a gas turbine installation with sequential combustion, in which hot gas is produced in a first combustion chamber and expanded in a subsequent turbine, and then flows through a subsequent second combustion chamber in which the fuel lance for injecting fuel into the hot gas is arranged. The fuel lance has a lance section which extends in the flow direction of the hot gas and includes at least an outer tube which is arranged concentrically to a lance axis, and a center tube which is concentrically arranged in the outer tube and in which the fuel is guided to the lance tip and is injected through first injection openings in the region of the lance tip into the hot gas. The fuel lance is modified for operation with syngas by the first injection openings being arranged directly on the lance tip, and by the first injection openings being oriented so that the fuel jets which emerge from them include an acute angle with the lance axis.

    摘要: In heat generators and burners, it is frequently necessary to realize discontinuous cross-sectional expansions of a flow duct. When the flow (U) passes over the step (10) formed in the wall (8) of the flow duct, coherent lateral separation vortices form which are propagated almost undamped downstream of the step and frequently represent the cause of thermo-acoustic vibrations of high amplitude. In accordance with the invention, vortex-generating elements (20) with a lateral pitch dimension (t) are arranged on a line transverse to the main flow (U) a distance (s) upstream of the step (10). Given an expedient selection of the pitch dimension (t), the lateral coherence of the separation vortex is enduringly destroyed.
