Definitions
- the invention relates to a catalytic burner on or for one Combustion chamber, in particular a power plant, with the features of Preamble of claim 1.
- a catalytic burner of this type is known a catalyst arranged in a ring and flowed through in burner operation and has a swirl generator through which the burner operates. It is the swirl generator is designed as an axial swirl generator in the axial direction is flowed through and the flow is subjected to a swirl. The axial swirl generator is concentric within the catalyst arranged so that the catalyst and swirl generator are flowed through in parallel.
- the present invention addresses the problem for one an improved catalytic burner of the type mentioned Specify embodiment, in particular the stability of the Combustion in the combustion chamber is increased.
- the invention is based on the general idea for the application of Burner flow with a swirl using a radial swirl generator i.e. a swirl generator, which is flowed through radially and thereby an axial emerging swirl flow generated.
- a radial swirl generator i.e. a swirl generator
- the flow resistance is smaller than one axial swirl generator. Accordingly, in the case of the invention Burner a smaller pressure drop, which is of particular advantage here, as well Flow through the catalyst or catalysts always with a pressure drop accompanied.
- the radial swirl generator have several rectilinear swirl generator channels, each opposite the Radial direction are inclined in the circumferential direction and a radially outer Connect the inflow space with a radially inner outflow space.
- This Construction has a relatively low flow resistance.
- the rectilinear swirl generator channels have one along their longitudinal direction constant cross-section, which makes it particularly easy constructed and therefore inexpensive catalysts in the swirl generator channels use.
- conventional monolith catalysts can be used rectilinear and parallel catalyst channels or cells can be used. This makes it possible to use standard components, which is special is inexpensive.
- catalysts can also be used that are made of zigzag folded or undulating sheets multilayer folding, layering or wrapping can be produced.
- a burner 1 according to the invention is connected to a combustion chamber 2 connected, in the combustion chamber 3 hot in the burner operation Combustion gases are generated at a preferred rate Application form of a gas turbine are fed to a power plant.
- the Burner 1 contains a catalyst arrangement 4 consisting of several Catalysts 5, which are flowed through in burner operation. Accordingly it is a catalytic burner 1.
- This burner 1 contains also a swirl generator 6, which is designed as a radial swirl generator, i.e.
- the swirl generator 6 is flowed through radially, here radially from the outside inside, giving the flow a twist.
- the radial swirl generator 6 is thereby between a radially outer inflow space 7 and a radial one outflow chamber 8 arranged inside.
- the swirl generator 6 and the Catalyst arrangement 4 are concentric with a longitudinal axis 9 of the Burner 1 arranged.
- the outflow chamber 8 leads in the axial direction, that is parallel to the longitudinal axis 9 to the combustion chamber 2 and thus connects the Downstream side of the swirl generator 6 with the combustion chamber 3.
- a transition 10 between the outflow chamber 8 and the combustion chamber 3 has here a cross-sectional enlargement 11, which in particular has a jump-like design can be.
- This cross-sectional widening 11 allows the burner 1 generated swirl flow in the combustion chamber 3 quasi burst, whereby on the one hand In the area of the cross-sectional expansion 11, a first vortex system 12 is generated and, on the other hand, a central second swirl system 13 in the combustion chamber 3 is generated.
- the second swirl system 13 is in the combustion chamber 2 generates a central recirculation zone 14 which has a flame front 15 in the Combustion chamber 2 in the so-called "plenum", ie in the vicinity of burner 1 anchored and stabilized.
- the radial swirl generator 6 has several Swirl generator channels 16, each in the same way opposite one of the central longitudinal axis 9 outgoing radial direction in the circumferential direction are inclined. This orientation of the swirl generator channels 16 results in the flow of the desired swirl. They are useful Swirl generator channels 16 tangential to an outlet cross section 17 aligned through which the gas flow from the outflow chamber 8 in the Combustion chamber 3 enters.
- the swirl generator channels 16 are expediently rectilinear and with one in their Longitudinal direction constant cross section formed. This makes it possible Particularly simple catalysts 5 in the swirl generator channels 16 use.
- the individual catalysts 5 consist of ceramic monoliths, which are coated in a suitable manner catalytically. It is also possible to use a stack or a catalyst 5 To build up winding of corrugated or zigzag folded sheet metal webs, the are also catalytically activated by a suitable coating.
- the Catalysts 5 each contain a large number of unspecified ones Catalyst channels, each parallel to and parallel to the Swirl generator channels 16 run.
- the catalysts 5 are arranged in the radial swirl generator 6, they take place Positioning on a radius that is larger than the radius of the Outlet cross section 17. Accordingly, the flow for Catalysts 5 have a smaller pressure drop than in a comparable arrangement with a pure axial flow.
- the flow rate in the Catalyst channels and the pressure loss of the catalysts 5 can on the one hand over the length of the catalysts 5 and their cell density and by the axial extension of the catalysts 5 and the swirl generator channels 16 and thus the swirl generator 6 can be set.
- the interpretation is expedient of the burner 1 so that the burner operation at least in the outflow chamber 8 Flow velocity is greater than a turbulent Flame speed at which the flame front 15 faces the burner 1 want to spread.
- This measure can spread the Flame front 15 in the outflow chamber 8 can be avoided.
- the burner 1 is designed so that a Dwell time of the flow in the outflow chamber 8 is less than one Time delay until self-ignition in the outflow chamber 8 inflowing, partially reacted hot fuel-oxidizer mixture.
- this measure can be the hot gas generation provided for the combustion chamber 3 be kept away from the outflow chamber 8. Wear the measures mentioned in each case that overheating of the catalysts 5 or Swirl generator 6 can be avoided.
- the embodiment of the Burner 1 a primary injection device 18, the multiple injectors 19th has that to a common ring line 20 for fuel supply are connected.
- the ring line is via a fuel feed line 25 fueled.
- the primary injection device conducts 18 upstream of the catalyst arrangement 4 in burner operation and thus upstream of the swirl generator 6 into the inflow space 7, in which the injectors 19 are arranged.
- the primary injector 18 has one for each swirl generator channel 16 has a separate injector 19, the fuel directly into the respective Swirl generator channel 16 injected or injected.
- Adequate Mixing of the introduced fuel with the supplied gas flow can be achieved in each swirl generator channel 16 upstream of the catalysts 5 an inlet section 21 can be formed, which serves as a mixing space.
- a secondary injection device 22 is also provided, the for the introduction of fuel downstream of the catalyst assembly 4 in the Outflow chamber 8 is used.
- This secondary injection device 22 has one here central, ie coaxial to the longitudinal axis 9 aligned injector 23, the is expediently designed or aligned so that it is in the fuel substantially parallel to the longitudinal axis 9 in the direction of the combustion chamber 2 in the Abströmraum 8 injected or injected.
- the secondary injection device can likewise 22 have a plurality of injectors 23.
- the injector (s) 23 of the secondary injector 22 also can be arranged eccentrically to the longitudinal axis 9. In particular, too lateral injection of the secondary fuel into the outflow space 8 be appropriate.
- the secondary injection device 22 can be used to start the burner 1 or sufficient combustion for transient operating conditions Combustion chamber 2 can be realized. Such a "pilot operation" is, for example required if the catalysts 5 are not yet sufficiently high Have reached operating temperature.
- the discharge of secondary fuel can in addition to the transient operating states when the burner 1 is started up at partial load conditions may be beneficial to the reliability of the Increase burner operation.
- FIGS. 5 to 8 show embodiments in which the injectors 19 quasi axially the fuel into the inflow space 7 inject or inject. 5 and 7 show an almost only axial injection, while in Fig. 6 the fuel for Is injected inclined towards the longitudinal axis, so that the introduced fuel also receives a radial component. The injection is still carried out outside of the swirl generator channels 16, but in the Swirl generator channels 16 entering gas flow takes the fuel and in deflects the inlet sections 21.
- each Swirl generator channel 16 is arranged at least one catalyst 5
- the Fig. 9 and 10 an embodiment in which in the circumferential direction only in every second Swirl generator channel 16 a catalyst 5 is arranged. Because of this design may also overheat the catalysts 5 or the swirl generator 6 be avoided.
- An embodiment is particularly expedient here has two primary injectors 18 and 18 ', the first primary injector 18 those swirl generator channels 16 with fuel supplied, in each of which one of the catalysts 5 is arranged. in the In contrast to this, the second primary injection device 18 'supplies the others Swirl generator channels 16, in which no catalyst 5 is arranged.
- Swirl generator channel 16 is equipped with a catalyst 5, can be used in a another embodiment also a different distribution of the catalysts 5 the swirl generator channels 16 are realized.
- the two catalysts 5a expediently differ and 5b for their catalytic activity. For example, the upstream arranged catalyst 5a have a higher activity to the Start the combustion reaction while the downstream catalyst 5b has a lower activity to overheat the catalyst 5b avoid.
- measures are exemplary shown, with the help of a wall 27 of the outflow chamber 8 against Overheating can be protected.
- This is conveniently done in the form of a active cooling and / or in the form of passive thermal protection.
- Film cooling 28 realized along the wall 27.
