Definitions
- the present invention relates to an open-cooled component for a gas turbine with a H adoptedgasbeetzmannten outer wall which at least partially defines a first cavity for a first means and are arranged in the fürgangso réelleen which fürgangso réelleen one hand into the cavity and on the other hand into the hot gas space and at least one second cavity for admixing a second means, which is in Strömungs- connection with the passage openings.
- the invention further relates to a combustion chamber and a gas turbine.
- Combustor walls as well as gas turbine blades are subject to high physical stress during normal operation of the gas turbine.
- these components are provided with a cooling. If air is used as a coolant, it is taken from a combustion chamber upstream compressor with diffuser and is lost to the combustion process. As a result, flame temperatures and NO x emissions increase.
- the wall of a combustion chamber is cooled either open or closed.
- the open cooling is designed as convective cooling, film cooling or as impact cooling with a cooling air outlet in the combustion chamber.
- the closed cooling requires a higher design effort and leads to an increased pressure loss due to the cooling air flow and the cooling itself.
- US Pat. No. 5,125,793 shows a turbine blade of a gas turbine with a double-walled outer wall enclosing a cavity.
- a flow channel for air is arranged in the double-walled outer wall.
- the cavity flows a liquid fuel, which is injected through through openings in the flow channel located in the double wall and there meets a catalyst.
- the catalyst Through the catalyst, the fuel decomposes endothermically into at least one combustible gas, which cools the blade.
- the air transports the gases to an outlet, from which the mixture can flow into the turbine and burn there.
- a disadvantage of the known concepts is that for the mixing of cooling air and fuel, a volume is to be provided by the reaction partners can ignite by auto-ignition or flashback in the components. As a result, under certain circumstances, stable combustion processes develop, so that the cooling effect of the fuel-air mixture is lost or the component can be damaged by the internal combustion.
- the second cavity is formed by supply channels provided in the outer wall, which are connected via transverse channels with the fürgangso réelleen formed as a passage bore, so that the two means are miscible only within the through holes.
- the invention further proposes a combustion chamber for a gas turbine with a wall element, which has a corresponding arrangement.
- the invention turns away.
- the previously formed between the double wall second cavity can be embedded as a supply channel in the outer wall, which is connected via separate transverse channels with the fürgangso réelleen.
- a possibility is thus created for the first time to substantially completely avoid a mixing volume in the component, as a result of which flashback and self-ignition in the component can be largely avoided.
- a component designed as a wall element of a combustion chamber it is possible to reduce a flame temperature increase in the case of open cooling, since the cooling air is now without the disadvantages described above can be enriched with fuel.
- the present invention therefore allows the cooling air flow to be increased without adversely affecting combustion.
- the present invention can also be achieved that the flame acoustics influenced, in particular detuned, can be.
- the fürgangs ⁇ réelle can be provided, for example, that the cooling air flows into the combustion chamber of the combustion chamber. Via the supply channel provided in the outer wall of the component, fuel can be supplied which mixes with the cooling air as it flows into the passage opening and thus forms a combustible mixture. A flashback is avoided insofar as there is no ignitable mixture in one of the supply channels or in the cavities before the mouth of the transverse channel in the fürgangs ⁇ réelle. Thus, the above-mentioned undesirable, sometimes dangerous, conditions can be avoided.
- the outer wall has a plurality of through holes, a plurality of supply channels extending between the holes, and a plurality of further transverse channels which crosslink the supply channels with the through holes. Due to the net-like structure of the channels and holes, a homogenization of the flowing mixture into the combustion chamber of fuel and cooling air can be achieved. In addition, it is possible to cool the component more uniformly, so that local overheating can be avoided.
- the component has at least two interconnectable layers.
- one layer may have the channel, while a second layer is formed on the combustion chamber side of a particularly resistant material.
- a high load capacity of the component can be achieved.
- the channel is introduced in at least one layer surface of one of the layers on the connection side. The channel can be introduced in this way by milling or similar material-removing processes in the surface of a layer, wherein by assembling the adjacent layers closed channels are formed. The channel can thereby be introduced into the component by means of known and also cost-effective methods.
- the cavity with a first fluid source and the supply channel with a second fluid source is connectable.
- Both fluids i.
- Means can be used to cool the blade so that the amount of air required for cooling is reduced. A larger amount of air is available to the combustion process, so that high flame temperatures and NO ⁇ emission can be reduced.
- the blade is basically the same principle as for the wall element of the combustion chamber at the bottom. Again, there is essentially no mixing volume, so that flashback and autoignition are largely avoided.
- the reliability of the gas turbine with respect to defective blades can be increased.
- the cooling air flow can be increased without negative effects on the combustion and the flame acoustics can be detuned.
- the invention also proposes that one of the two fluid sources is an oxidant source and the other fluid source is a fuel source.
- an ignitable mixture is formed only in the region of the mouth of the fürgangs ⁇ réelle in the flow channel of the gas turbine, when the mouth of the channels is arranged sufficiently close to the mouth of the passage opening in the flow channel.
- the invention also proposes a gas turbine, wherein the gas turbine is a combustion chamber according to the invention.
- the negative effects, as described above, can be largely reduced by supplying fuel, wherein the combustion chamber according to the invention enables safe operation with respect to auto-ignition and flashback. Furthermore, it is advantageous to influence the flame acoustics in order to reduce the stresses and wear caused by this.
- the invention also proposes a gas turbine with a component designed as a blade.
- the cooling effect for the blade of the turbine unit which can be designed as a fixed guide blade as well as a rotating rotor blade, can be improved by increasing the cooling air flow, wherein the negative effects on the combustion can be largely avoided.
- an influence on the detuning of the flame acoustics can be exerted. Wear and tear can be further reduced.

- a fluid fuel can be supplied, which is guided via the transverse channels 4 to the fürgangso réelleen 3 and is introduced there into the flow of cooling air.
- Fig. 2 illustrates this system of channels for the fuel supply.
- the wall element 2 has two interconnectable layers 6, 7. In the connection-side layer surface of the layer 6, the channel system is introduced by milling. By the connection of the layers 6 and 7 closed channels 4 and 9 are formed.
- Fig. 3 shows a plan view of the surface of the layer 6 of the wall element 2 in which the channels 4 and 9 are introduced.
- the connecting channel 9 is formed integrally with the wall element.
- the combustion chamber of a plurality of wall elements 2 is modular.
