- a suitable ignition system may be arranged in or on this air supply channel (not shown in the figure).
- the pilot burner system has a combustion chamber 7 zuwerende outlet opening 9, in whose area a twist blading 11 is arranged in the air supply channel. Gas can be injected from the inner gas supply channel 3 in the area of the swirl blading or upstream of the swirl blading into the air supply channel 5 by means of nozzle openings 13. Oil from the oil supply channel can be injected by means of oil nozzles 15 downstream of the swirl blading into the supplied air or the supplied inert material.
- the pilot burner system can be operated in a conventional manner with oil and / or gas as a diffusion burner, in which the fuel is injected directly into the flame.
- a diffusion burner in which the fuel is injected directly into the flame.
- the pilot burner system it is also possible to operate the pilot burner system as a premix burner, in which the fuel is thoroughly mixed with air before the mixture is fed to the flame.
- the main burner system surrounding the pilot burner system comprises a radial outer air supply channel 17, also called an annular air channel, through which swirl blades 19 of a swirl blading extend.
- These swirl vanes 19 have first gas nozzles 21 and second gas nozzles 23, through which fuel gas can be injected into the air flowing in through the radial air supply duct 17.
- air can also be injected by means of oil nozzles 25 oil.
- the first gas nozzles 21 and second gas nozzles 23 located in the swirl vanes 19 and the oil nozzles 25 are supplied with fuel via a radially inner fuel supply arrangement, the so-called hub 27.
- this first and second annular gas distribution channels 29 and 31 are arranged, which supply the gas nozzles 21 and 23 with gas.
- an annular oil distribution channel 33 is arranged, which supplies the oil nozzles 25 with oil.
- the gas distribution channels 29, 31 and the oil distribution channel 33 are supplied via gas supply channels 35, 37 and via an oil supply channel 39 with the appropriate fuel.
- the gas supply channels 35, 37, which supply the gas distribution channels 29, 31 with fuel, are integrated in a common gas supply pipe 41.
- For the oil supply channel 39 is a separate oil supply pipe 43 before.
- the integration of the two gas supply channels 35, 37 in a common gas supply pipe 41 has the advantage that the aerodynamics of the burner with respect to the air flowing into the air supply channels 5, 17 air compared to a burner with only a single gas supply channel and a single set of gas nozzles not changed.
- the burner according to the invention can therefore replace existing burners in existing combustion systems without the aerodynamics of the combustion system thereby changing.
- a first concrete embodiment of the burner according to the invention in particular the gas supply pipe 41 with the gas supply channels 35, 37 will be described below with reference to the FIGS. 2 to 5 described.
- the gas supply channels 35, 37 are arranged coaxially with each other in the gas supply pipe 41.
- the gas supply channel 37 supplying gas to the second annular gas distribution channel 31 is formed by the lumen of an inner tube 35, whereas that of the first annular gas distribution channel 29 supplying gas supply channel 35 from the cavity between the outer surface of the inner tube 45 and the inner surface of an outer tube 46 is formed.
- the outer tube 46 forms the outer wall of the gas supply pipe 41.
- the inner tube 45 is cooled by the gas flowing therethrough and the outer tube 46 is heated by the warm compressor air flowing along, the two tubes 45, 46 experience different thermal expansions.
- the inner tube 45 is formed in two parts, wherein between the tube parts 45, 45 'an elastic compensation element 47 is arranged.
- the elastic compensation element is designed as a bellows, which allows an axial displacement of the two tube parts 45, 45 'against each other. Different thermal expansions between the outer tube 46 and the inner tube 45 can thus be compensated.
- the compensation element can also be arranged on the outer tube 46. Also, the provision of two compensation elements, one on the inner tube 45 and one on the outer tube 46, is possible. For the compensation element on the outer tube 46, this is analogous with respect to the design of the compensation element on the inner tube 45.
- an adapter piece 49 is provided, which has the annular flow cross section of the first gas supply channel 35 and the circular flow cross section of the second gas supply channel 37 in flow cross sections with maximum flow areas for the flowing gas transferred. In this way, the flow from the gas supply channels into the respective annular gas distribution channels can be optimized, whereby more uniform heat transfer rates can be achieved and the life and the life prediction of the burner can be improved.
- the adapter piece 49 is in FIG. 3 shown in a perspective view. It has an approximately semicircular curved edge portion 51 with an outer surface 53, which is adapted in its radius of curvature to the wall of the outer tube 46. In addition, it has a circular projection 55, which can be connected to the inner tube 45.
- the circular flow cross section and the annular flow cross section are converted into flow cross sections optimized with regard to the creation of maximum flow areas.
- the optimized flow cross sections which result with the aid of the adapter piece at the outlet of the gas supply pipe 41, are in FIG. 4 shown. This shows the flow openings provided with the corresponding flow cross-sections corresponding inlet openings 57, 59 to the annular gas distribution channels 29, 31st
- FIG. 5 shows an enlarged section FIG. 2 in which the arrangement of the adapter piece 49 and the connection with the inner tube 45 and the outer tube 46 are shown.
- the adapter piece 49 is connected by means of welded connections on the one hand to the hub 27 and on the other hand to the inner tube 45 and the outer tube 46. Due to the only part-circular configuration of the adapter piece 49, which is a semicircular configuration in the present embodiment, it is possible first to weld the adapter piece 49 to the hub 27, then to weld the inner tube 45 on the adapter piece 49 and finally over the outer tube 46 and to weld with the adapter piece 49. If the adapter piece 49 would have a completely annular wall element, in particular the dense bonding of the part of the adapter piece 49 forming the inner gas supply channel to the hub 27 would be difficult to accomplish.
- the referring to the FIGS. 2 to 5 described first specific embodiment of the burner according to the invention has the advantage that has a negative impact on the air flow
- the radial air supply channel 17 can avoid, since no change in the outer hub geometry or the gas supply pipe 41 needs to be compared to a burner with only one gas distribution channel.
- the flow cross-sections can be optimally utilized with the aid of the adapter piece, whereby unnecessary pressure losses are avoided.
- the embodiment according to the first concrete embodiment allows a robust construction, which also allows easy mounting.
- FIG. 6 shows the hub 27 of the burner according to the invention with a arranged in its center pilot burner 63 and the gas supply pipe 141 in a perspective view.
- a burner support 65 can be seen, in which there are two connections 67, 69 for the two gas supply ducts 135, 137 located in the gas supply pipe 141.
- the gas supply pipe 141 of the second specific embodiment is in FIG. 7 shown in a perspective view. It differs from the gas supply pipe 41 of the first concrete embodiment in that the gas supply channels 135, 137 are arranged side by side instead of concentric with each other.
- the geometry of the gas supply channels 135, 137 is selected such that there are flow cross sections with maximum flow areas at least at the hub-side outlet end 71 of the gas supply tube.
- the two gas ports for the gas supply pipe 141 are arranged. These are also arranged side by side, but a connecting line A, which connects the centers of the two gas ports 67, 69 with each other by 90 ° with respect to a connecting line B, the centers of the gas supply channels 135, 137 at the hub end of the gas supply pipe 141 connects to each other Turned 90 °.
- the twisting can also be done by other angles than 90 °, if another arrangement of the gas ports 67th , 69 in the burner carrier 65 is desired.
- the gas supply pipe 141 of the second concrete embodiment of the burner according to the invention can be designed in particular as a cast construction. In such, in particular with a twisting of the channels in the pipe by 90 °, a constant wall thickness over the entire component can be achieved.
- the design of the gas supply pipe 141 according to the second specific embodiment offers the particular advantage that the distribution of the gas supply channels in two separate gas connections between the burner carrier and the hub takes place. This simplifies the assembly of the burner. The burner carrier flange is then only provided with two fitting holes.
- the tube construction hardly changes the aerodynamics compared to a burner with only one gas distribution channel in the hub. Since the transition section is located in the vicinity of the burner support - and thus away from the air ducts of the pilot burner and the main burner - this change in the gas supply pipe leads to a gas supply pipe with only one gas supply channel not to a significant change in the aerodynamics of the burner.
