摘要： What is described is a burner system with a premix burner (1), in which is provided at least one vortex generator (2), through which passes an air-containing gaseous main flow (ZL) which flows axially through the premix burner (1) and into which gaseous and/or liquid fuel is injected, downstream of the vortex generator (2), as a secondary flow for generating a fuel/air mixture, and with a combustion chamber (5) which adjoins the premix burner (1) downstream of the latter and has a combustion chamber cross section (C2) which is larger than the flow cross section (C1), delimited by the premix burner (1), directly upstream of the combustion chamber (5). The invention is distinguished in that, between the premix burner (1) and the combustion chamber (5), a flow duct (10) is provided, delimited by side walls which create a gradual transition between the flow cross section (C1) and the combustion chamber cross section (C2), and in that upstream, within and/or downstream of the flow duct (10) is provided at least one flow stall structure (11), by means of which the fuel/air mixture passing through the flow duct (10) is separated locally from the side wall of the flow duct (10).

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： In a combustion chamber, a gaseous or liquid fuel is injected as a secondary flow into a gaseous, channelized main flow. The main flow is directed to pass over a plurality of vortex generators (9) arranged side by side over the width or circumference of the channel (20) through which the flow passes. The height (h) of the vortex generators is at least 50% of the height (H) of the channel through which the flow passes or of that part of the channel associated with the vortex generators. The secondary flow is introduced into the channel (20) in the immediate vicinity of the vortex generators (9). Longitudinal vortices without any recirculation region are produced in the channel through which the flow passes by means of the new static mixer. Extraordinarily short mixing distances, with a low pressure loss at the same time, are thus achieved in a combustion chamber according to the invention.

摘要： A reheat burner includes a channel with a lance projecting thereinto to inject a fuel over an injection plane perpendicular to a channel longitudinal axis. The channel and lance define a vortex generation zone upstream of the injection plane and a mixing zone downstream of the injection plane in the hot gas direction. The mixing zone has a cross section with diverging side walls in the hot gas direction. The diverging side walls define curved surfaces in the hot gas direction having a constant radius.
