Definitions
- the present invention relates to a combustion chamber intended in particular for use in a gas turbine. More specifically, the present invention relates to the air guidance of the compressed air supplied to the combustion chamber.
- the typical structure of a gas turbine consisting of a compressor region, a combustion chamber region and a turbine region is well known and will not be explained in more detail below.
- the compressed air that is supplied to the combustion chamber is introduced into the combustion process in a flame tube and also used for cooling the combustion chamber.
- research and development in the field of gas turbines is aimed at continually reducing pollutant emissions from gas turbines.
- the focus is on the pollutants NO x , CO 2 and CO and unburned hydrocarbons.
- the pollutants in the combustion process of a gas turbine for example, by a lean mixture of the fuel-air mixture, ie more compressed air must be added to the fuel-air mixture, or can be achieved by optimal temperature distribution in the flame tube.
- EP 0 732 546 B1 discloses a construction of the prior art to meet these requirements.
- the compressed air which is supplied to the combustion chamber from the compressor region of the gas turbine is divided into two partial streams.
- a partial flow is used for combustion in the flame tube, another the cooling of the outer wall of the combustion chamber, wherein the cooling air then enters the post-primary combustion zone.
- a disadvantage of this structure is that only a predetermined proportion of the compressed air flow is ready for cooling. In other words, the lower the pollutant a gas turbine is designed, the less cooling air is available. Consequently, the efficiency of the gas turbine in favor of lower pollutant emissions must remain low.
- the prior art according to EP 0 896 193 B1 has the disadvantage that no direct cooling in the flame tube interior can be provided by openings in the wall in the region of the post-primary combustion zone or secondary zone. This prior art thus does not achieve optimal cooling performance and is limited in the operation of the gas turbine.
- the invention provides a combustion chamber for a gas turbine.
- the flame tube of the combustion chamber is in the flow direction at least in a mixing zone for mixing a fuel with air to a fuel-air mixture, and a primary combustion zone or primary zone and a post-primary combustion zone or secondary zone.
- a mixing zone for mixing a fuel with air to a fuel-air mixture
- a primary combustion zone or primary zone and a post-primary combustion zone or secondary zone In the region of the mixing zone, which is formed in the vicinity of the burner, at least one opening is generally provided via channels of the burner into the interior of the flame tube.
- the so-called mixing opening is likewise provided. This at least one opening or mixing opening serves to cool the combustion process.
- About the openings mentioned compressed air which is previously compressed in the compression region of the gas turbine, enters the flame tube. The compressed air is provided for the cooling of the flame tube and passes through the openings described proportionally in the mixing zone and in the post-primary combustion zone.
- the air for combustion at a higher temperature in the burner of the combustion chamber passes. Since the combustion temperature is raised in this way, the gas turbine can be operated with less fuel and still achieve the same temperature. This measure thus increases the efficiency of the gas turbine.
- the new arrangement also allows the combustion gases in the post-primary combustion zone to be cooled.
- the supply of air to the combustion process can be made variable, since theoretically all the compressed air could be fed into the combustion process.
- the figure shows a schematic cross-sectional view of a combustion chamber according to the invention.
- Reference numeral 1 shows a combustion chamber according to the embodiment with a flame tube 3 and a baffle 2 arranged radially outside the flame tube.
- the combustion chamber 1 is part of a gas turbine (not shown) which is operated with gas and / or liquid fuel.
- the flame tube is widely Cylindrical design. Compressed air flows through a compressor air duct onto the impact grille. Through the openings 4 of the baffle, the compressed air flowing from a compressor, or from the compressor region of the gas turbine to the combustion chamber, divided into numerous individual flows.
- the openings 4 of the impact grid are formed as nozzles, so that the inflowing compressed air impinges jet-shaped.
- the arrangement and geometry of the openings 4 of the impact grille can be adjusted so that the desired cooling performance is achieved on the surface of the flame tube.
- the distribution of the impact cooling in the air portion 11 and the air portion 12 is designed adjustable. In this embodiment, this is achieved by changing the geometry of the openings 5 to the post-primary combustion zone 18 during operation. By cooling the flame tube 3, the service life of the machine elements used is increased and at the same time the air of the flow rate of the burner 11, 13 and the flow rate mixing port 12 is heated.
- the impact grille is formed in this embodiment as a perforated plate which surrounds the flame tube (3) in the circumferential direction. Since the compressed air is not only passed along the outer wall of the flame tube 3, but with increased speed, preferably triggered by the nozzle action of the openings of the perforated plate 2, divided into numerous individual flows impinges on the outer surface of the flame tube, the cooling capacity is significantly increased.
- the flow of compressed air directed to the flame tube 3 may also be angular, e.g. do not impinge perpendicular to the flame tube 3.
- a device for dividing the directed to the flame tube 3 flow compressed air can preferably be provided in the compressor air passage 9.
- this embodiment of the invention is also open to understand in which zones of the flame tube is cooled by impingement air.
- 1 shows an embodiment in which both the pre- and post-primary burns cooling zone is cooled by impingement air.
- the present invention is not limited to the impingement cooling with individual flows 10 striking the flame tube 3 substantially perpendicular or at an angle. Rather, a laminar flow along the outer wall of the flame tube 3 can provide the desired cooling performance. It is essential to the invention, in the first place, that the air used for cooling reaches the flame tube 3 both via the mixing openings 5 and via the openings 6. In addition, a combination of the described flow types for the cooling of the flame tube 3 as well as support by other cooling methods known in the art is conceivable.
- the thus preheated air passes through the air duct 6 in the burner 7. There, the air is premixed with the fuel, which flows substantially along the fuel flow. Because the temperature of the fuel-air mixture is increased due to the preheated air used for the cooling of the flame tube compared to conventional fuel-air mixtures, the gas turbine with reduced fuel consumption can reach the same temperature as known from the prior art gas turbines.
- the supplied compressed air is used substantially completely for the cooling of the fire tube 3 and divided into a flow portion 11, 13 to the opening 6 of the mixing zone 15 and a flow portion 12 to the opening 5 of the post-primary combustion zone 18.
- the Mischö Stamms- flow 14 then flows through a plurality of mixing openings 5 substantially perpendicular to the fuel flow 8 in the flame tube 5.
- the flow can be carried out by the mixing openings 5 and / or through the opening 6 to the mixing zone 15 controllable or adjustable. This can be done, for example, by changing the flow cross-section through said openings, but also by all other measures known to those skilled in the art. LIST OF REFERENCE NUMBERS
