- the present invention relates to a combustion chamber for combustion of a combustible fluid mixture with one at the Combustion chamber arranged burner.
- the invention further relates to a method for cooling a combustion chamber according to the invention.
- Combustion chambers are usually provided with a flow guide inside, which is called a liner.
- a liner Basically they are different Concepts for combustor arrangements.
- combustion chamber arrangements are used, which are made up of a large number of individual combustion chambers, that lead to a common opening.
- the opening of a gas turbine is preferably an annular opening trained the same time the transition to the turbine room represents.
- a combustible fluid mixture is supplied to the burner, which ignites in the combustion chamber and flows through the liner Is guided towards the outlet opening.
- Another concept a combustor assembly looks instead of a multitude of Single combustion chambers a single annular ring combustion chamber in front. In such an annular combustion chamber, ignites occur in burners combustible fluid mixture, burns in it and expands towards the exit opening.
- the liner arranged inside the combustion chamber is exposed to high physical stress, which is why it is subject to wear.
- one Arrangement provided that allows the liner, especially parts of it. are in the stand the technology arranged rail-like rods over which individual liner elements connected to the combustion chamber wall are.
- the arranged between the liner and the housing Rails are in a relatively cool area the combustion chamber arranged so that disassembly from the inside is not easy to carry out.
- the liner too, because of the fastening inside complicated to manufacture. Beyond that arise Thermal stress due to the very high side walls.
- the invention is therefore based on the object of providing a fastening for liner elements of a combustion chamber, with which an assembly simplification can be achieved from the inside of the liner.
- the rails are arranged on the hot gas side and form part of the inner wall of the combustion chamber. This allows the liner connections point outwards, whereby the Liner is structurally simpler and also flatter can be. It can also create internal tension be reduced. Internal disassembly and assembly can be reached from the inside of the liner elements.
- the liner element be by means of a fastening element provided on the outside of the rail element is definable.
- Standard fasteners can be advantageous used to attach the liner elements to fix the rail elements. Cost and assembly effort can be reduced.
- the fastener is formed by a screw. So a detachable connection can be achieved by means of conventional, known Tools is executable. Special tools to run the attachment can be avoided.
- the fastener formed by a clamping element in particular a clamping spring is.
- clamping springs one can be special simple and quick assembly or disassembly of liner elements can be achieved. This is particularly advantageous if the service life of a system such as one Gas turbine, represents an essential cost factor. low Downtimes can be achieved.
- the Rail element at least a coating on the combustion chamber side having.
- the coating can be used both for Reduction of physical stress during the Intended operation as well as to reduce the Wear. Maintenance intervals can be extended become.
- a coating can also be provided be related to, for example, an inert surface to form the fluid in the combustion chamber.
- the Rail element can also be used on its entire surface be provided with a coating, for example a Simplify coating process.
- the rail element is liner-like for manufacturing a fluidic connection between a channel of the rail element and a channel of the liner element for a coolant. It can advantageously be a cooling system can be achieved, which at the same time cooling the Liner elements as well as the rail elements.
- the combustion chamber be a has closed cooling.
- the coolant can thus be advantageous be fed to the combustion chamber, it being in As part of the cooling function, energy absorbed back into the process supplies. On the one hand, energy loss due to Cooling function are reduced and on the other hand the coolant can be used for combustion in the combustion chamber. A high one Efficiency can be achieved.
- the Combustion chamber in a turbomachine especially one Gas turbine is arranged. Maintenance effort and downtimes a gas turbine can be further reduced.
- the invention also provides a method for cooling a proposed combustion chamber according to the invention, wherein a Coolant flowing through liner rail at least partially in the circumferential direction of the combustion chamber in the direction of the liner element flows and in or against a channel of the liner element the flow direction of the combustion chamber is redirected.
- a channel provided in a liner element can advantageously which is provided, for example, for cooling the liner element is for a discharge of the flowing through the liner rail Coolant can be used.
- one closed cooling system for a combustion chamber constructive effort for the flow of the coolant be reduced. Components and assembly effort can also be reduced if, for example, a separate cooling fluid drain can be saved.
- air is used as the coolant becomes.
- a part can be branched off from an intake air, the is used for cooling.
- Particularly advantageous for Part of the air used for cooling is returned to the combustion chamber, so that on the one hand the one absorbed by the cooling function Heat as well as the energy to provide the Cooling air is at least partially fed back into the process can be.
- a further increase in efficiency can be achieved.
- Fig. 1 shows a section of a gas turbine with an inventive Combustion chamber 1, which in the present case as Annular combustion chamber is designed.
- the combustion chamber 1 has a Housing 7 in which a liner 4 is arranged.
- a burner 2 opens out via a combustible fluid is supplied.
- an outlet opening 3 is provided, which with an entrance to a flow channel downstream Gas turbine is connected, which is not shown.
- a rotor shaft 14 is arranged in the center. 2 is the upper part of the combustion chamber 1 enlarged in section shown.
- the combustible supplied via the burner 2 Fluid is ignited in a combustion chamber 15 in the liner 4 and flows in the direction of outlet opening 3 to the following one Turbine.
- the liner 4 is built up in segments from liner elements 5, which are each adjacent to one another via rail elements 6 are connected (Fig. 3).
- About the rail elements 6 are Liner elements 5 at the same time elastic with the combustion chamber housing 7 of the combustion chamber 1 set.
- Rail elements 6 arranged on the combustion chamber side and protrude between two adjacent liner elements 5 Outside.
- the rail element has 6 openings for fastening 17 through which a fastening device 8 can be inserted is, via which the rail element 6 is elastic with the housing 7 of the combustion chamber 1 is fixed.
- Expansions that occur are the fastening devices 8 formed elastically in its longitudinal extent.
- Sealing between the rail element 6 and the Liner element 5 is a sealing element 16 in each case intended.
- the rail element 6 lies on the hot gas side between the two adjacent liners 5 on the outside not shown lying liner hooks and tensions the liner elements 5 firmly.
- the rail element 6 also has alternating its longitudinal extent alternately staggered Fastening areas and cooling areas.
- Rail element openings 11 are provided, via the one Coolant from the rail element 6 via one in one Edge region of the liner element 5 provided channel 20 in the Channel 13 of the liner element 5 flows.
- coolant flowing in the channel 13 becomes through the channel 20 introduced coolant also deflected in the direction of flow 21 (Fig. 4).
- the rail element 6 is on the combustion chamber side provided with a coating 9 which is opposite the hot gas flow a thermal inside the combustion chamber 1 Isolation causes.
- the coating 9 forms a Protection by which the aging of the rail element 6 is reduced becomes.
- the Coolant channel 12 of the rail element 6 and the coolant channel 13 of the liner element 5 has the rail element 6 liner-like toes, in which the liner elements 5 on the housing 7 of the combustion chamber 1 are attached. Of these will the coolant flow in the circumferential direction into the liner elements 6 dissipated.
