Definitions

  • the invention relates to a catalytic burner on or for a combustion chamber, in particular a power plant, with the features of the preamble of claim 1.
  • a catalytic burner which has a ring-shaped arranged and flowed through in the burner operation catalyst as well as a traversed in the burner operation swirl generator.
  • the swirl generator is designed as an axial swirl generator, which is flowed through in the axial direction and thereby acts on the flow with a swirl.
  • the axial swirl generator is arranged concentrically within the catalyst so that catalyst and swirl generator are flowed through in parallel.
  • Another catalytic burner of this kind is from the EP 0 810 405 A2 known, in which the swirl generator is designed as a radial swirl generator, which between a radially outer inflow space and a radially inward lying, axially leading to the combustion chamber outflow space is arranged.
  • the swirl generator is designed as a radial swirl generator, which between a radially outer inflow space and a radially inward lying, axially leading to the combustion chamber outflow space is arranged.
  • two radial swirl generators are provided which lead to a primary combustion zone. This is followed by a secondary combustion zone, followed by a homogeneous combustion zone. Between the secondary combustion zone and the homogeneous combustion zone, a catalyst is arranged which forms a catalytic combustion zone.
  • a burner which has a radial swirl generator.
  • This has a plurality of rectilinear swirler channels, which are each inclined relative to the radial direction in the circumferential direction and connect an inflow space with a discharge space.
  • the present invention is concerned with the problem of providing for a catalytic burner of the type mentioned in an improved embodiment, in particular, the stability of the combustion in the combustion chamber is increased.
  • the invention is based on the general idea of using a radial swirl generator for impinging the burner flow with a swirl, ie a swirl generator, which is flowed through radially and thereby generates an axially emerging swirl flow.
  • a swirl generator which is flowed through radially and thereby generates an axially emerging swirl flow.
  • the flow resistance is smaller in a radial swirl generator than in one axial swirl generator. Accordingly, the burner according to the invention results in a smaller pressure drop, which is of particular advantage here, since the flow through the catalyst or catalysts is always accompanied by a pressure drop.
  • the radial swirl generator has a plurality of rectilinear swirler channels, which are each inclined relative to the radial direction in the circumferential direction and connect a radially outer inflow space with a radially inner outflow space.
  • This construction has a relatively low flow resistance.
  • the rectilinear swirl generator channels have a constant cross section along their longitudinal direction, which makes it possible, in particular, to use particularly simple and thus inexpensive catalysts in the swirl generator channels.
  • conventional monolith catalysts with straight and parallel catalyst channels or cells can be used. This makes it possible to use standard components, which is particularly inexpensive.
  • monolith catalysts it is also possible to use catalysts which are produced from zig-zag folded or wave-shaped metal sheets by multilayer folding, layering or winding.
  • the catalysts are integrated according to the invention in the radial swirl generator, resulting in a particularly compact design for the burner according to the invention.
  • a burner 1 is connected according to the invention to a combustion chamber 2, in the combustion chamber 3 in the burner operation hot combustion exhaust gases are generated, which are supplied in a preferred embodiment of a gas turbine of a power plant.
  • the burner 1 contains a catalyst arrangement 4, consisting of a plurality of catalysts 5, which are flowed through in the burner operation. Accordingly, it is a catalytic burner 1.
  • This burner 1 also contains a swirl generator 6, which is designed as a radial swirl generator, ie, the swirl generator 6 is flowed through radially, here radially from outside to inside, where it imparting a twist to the flow.
  • the radial swirl generator 6 is arranged between a radially outer inflow space 7 and a radially inner outflow space 8.
  • the swirl generator 6 and the catalyst arrangement 4 are arranged concentrically to a longitudinal axis 9 of the burner 1.
  • the outflow chamber 8 leads in the axial direction, ie parallel to the longitudinal axis 9 to the combustion chamber 2 and thus connects the outflow side of the swirl generator 6 with the combustion chamber.
  • a transition 10 between the discharge chamber 8 and the combustion chamber 3 has here a cross-sectional widening 11, which may be formed in particular jump-like.
  • this cross-sectional widening 11 the swirl flow generated in the burner 1 can practically burst open in the combustion chamber 3, whereby a first swirl system 12 is generated on the one hand in the region of the cross-sectional widening 11 and, on the other hand, a central second swirl system 13 is generated in the combustion chamber 3.
  • a central recirculation zone 14 is generated in the combustion chamber 2, which anchors and stabilizes a flame front 15 in the combustion chamber 2 in the so-called "plenum", ie in the vicinity of the burner 1.
  • the radial swirler 6 has a plurality of swirler channels 16 which are each inclined in the same manner with respect to a radial direction extending from the central longitudinal axis 9 in the circumferential direction. This orientation of the swirl generator channels 16 results in the flow through the desired swirl.
  • the swirl generator channels 16 are aligned tangentially to an outlet cross section 17, through which the gas flow from the outflow chamber 8 enters the combustion chamber 3.
  • the swirl generator channels 16 are rectilinear and formed with a constant in their longitudinal direction cross-section.
  • the individual catalysts 5 consist of ceramic monoliths, which are catalytically coated in a suitable manner. It is likewise possible to build up the catalysts 5 by means of a stack or a winding of corrugated or zig-zag-folded sheet metal webs, which are likewise activated catalytically by a suitable coating.
  • the catalysts 5 each contain a plurality of unspecified catalyst channels, each parallel to and parallel to the swirl generator channels 16.
  • the catalysts 5 or the catalyst arrangement 4 are integrated into the swirl generator 6. Of particular importance is that in this structure, the guided through the catalysts 5 flow is applied simultaneously with the desired twist.
  • the design of the burner 1 is carried out so that in the burner operation, at least in the outflow chamber 8, the flow velocity is greater than a turbulent flame velocity with which the flame front 15 would like to spread to the burner 1.
  • the burner 1 is designed so that in burner operation, a residence time of the flow in the discharge chamber 8 is smaller than a time delay until the self-ignition of the flowing into the outflow chamber 8, partially reacted hot fuel-oxidizer mixture.
  • the hot gas generation provided for the combustion chamber 3 can be kept away from the outflow space 8.
  • the embodiment of the burner 1 shown there comprises a primary injection device 18, which has a plurality of injectors 19 which are connected to a common ring line 20 for fuel supply.

  • the secondary injection device 22 By means of the secondary injection device 22, sufficient combustion in the combustion chamber 2 can be realized for starting the burner 1 or for transient operating states. Such a "pilot operation" is required, for example, when the catalysts 5 have not yet reached a sufficiently high operating temperature.
  • the injectors 19 introduce the fuel virtually radially into the inflow space 7 or into the inlet sections 21 of the swirl generator channels 16, respectively Fig. 5 to 8 Embodiments in which the injectors 19 inject or inject the fuel virtually axially into the inflow space 7.
  • the Fig. 5 and 7 show a nearly exclusively axial injection, while at Fig. 6 the fuel is injected inclined to the longitudinal axis, so that the introduced fuel also receives a radial component.
  • the injection takes place outside of the swirl generator channels 16, but the gas flow entering the swirl generator channels 16 entrains the fuel and deflects it into the inlet sections 21.
  • the mixing devices 24 are arranged in the inlet sections 21 of the swirl generator channels 16.
  • each catalyst 5 or each injector 19 is associated with such a mixing device 24.
