Definitions
- the present invention relates to a combustion chamber according to Preamble of claim 1. It also concerns a Method for operating a gas turbine group with a such combustion chamber.
- the principle of mixture formation is based on in a combustion air flow by means of a Inflow channel arranged vortex generators to vortex generate, and by means of the vortex generators arranged fuel lances a fuel in the to introduce swirled combustion air flow.
- swirled combustion air flow finds an intense Mixing the fuel with the combustion air instead, so that an intensely and evenly premixed Mixture available for low-emission combustion stands.
- temperatures are aimed at, which have a certain safety margin against extinguishing the flame, whereby the The blades themselves are subjected to a higher temperature than is the case with conventional combustion chambers is.
- the invention seeks to remedy this.
- the invention as it is characterized in the claims, the Task based on a combustion chamber of the beginning mentioned type within the hot gas flow To accomplish temperature gradation.
- a temperature gradation within the hot gas flow leaves preferably achieved in an annular combustion chamber the fuel over a number in the circumferential direction of the Ring combustion chamber acting fuel lances is injected.
- Each of these fuel lances has several different ones directed nozzles through which the fuel in the Flow cross section of the annular combustion chamber introduced with which a sectorial enrichment of the Firing mixture is reached.
- Such a configuration is excellently suited, a sectorally different Enrichment of the fuel mixture to accomplish the injected fuel is mainly distributed within the sector assigned to it, which makes it possible to over the temperature distribution to influence the fuel mixing. So that becomes a Temperature gradation reached in the radial direction, which the Representing profile flow for the blades to be loaded.
- Vortex generators which are placed upstream of the fuel lances.
- An essential one The advantage of this arrangement is that the Vortex generators according to sector, according to the fuel injection be arranged, and there also an individual Can produce effect.
- Another important advantage of the invention is in that the temperature gradation is targeted in the radial direction can be customized.
- the introduction is preferred of the fuel handled so that the scoop feet relieved at a given average temperature of the hot gases become.
- the temperature of the hot gases is in the range the blade feet lower than the average temperature, this loss can easily be compensated by along the much larger area of the rest of the blade profile a slightly higher temperature of the hot gases becomes.
- the caloric load in the area decreases the weak points, so the cooling of the blading reduce accordingly what ultimately turns into a Efficiency improvement reflected.
- the turbine inlet temperature can be the same for the same service life be increased accordingly, leading to an increase in the efficiency and performance of the machine leads.
- Another advantage of the invention is that by targeted temperature grading, especially in the transients Load ranges a better transient behavior of the rotor is what leads to smaller games between the Stator and the rotating parts leads.
- annular combustion chamber 1 shows, as can be seen from the shaft axis 10, an annular combustion chamber 1, which is essentially in the form of a contiguous annular or quasi-annular cylinder occupies.
- a combustion chamber also consist of only one cylinder.
- Fig. 1 shows only the significant part of the Annular combustion chamber 1, namely the vortex formation that leads to a Fuel lance with temperature gradation and downstream located and to be applied turbine.
- the main flow 4 is always a combustion air flow, its temperature and Composition can be very different.
- the combustion air 4 is caused by the vortex generators 200 twists that in the subsequent premixing and firing zone 5a no more recirculation areas in the wake of the vortex generators 200 occur.
- this premixing and firing zone 5a are several fuel lances 3 disposes of the supply of a fuel 11 and a supporting air 12 take over.
- the feeder this media 11, 12 to the individual fuel lances 3 can accomplished, for example, by a ring line, not shown become.
- the one from the vortex generators 200 triggered swirl flow is injected with the sector Fuel 7a, 7b in operative connection, such that by a corresponding regulation of the amount of fuel over the individual Sectors a different size of the individual resulting from the action of the vortex generators 200 Partial flows of the combustion air 4 results in the subsequent combustion a different temperature profile triggers.
- a temperature gradation 8 over the flow cross section is graphical in the figure and represented qualitatively. How easy to deduce from this presentation is applied to this temperature-graded hot gas front the blades via corresponding guide vanes 9 a turbine 2. According to the temperature gradation 8 the shovel feet are calorically less stressed, but the the remaining blade surface is exposed to a slightly higher temperature, so that's for efficiency and performance the relevant mean hot gas temperature is maintained.
- Fig. 2 shows, for each fuel lance 3 in the area Vortex generators 200 one for an annular annulus combustion chamber 1 typical chamber formed, which also includes lateral vortex generators 200 can be attached.
- the sectoral fuel injection 7a, 7b depends on the position of those placed upstream Vortex generators 200, this injection to ensure a temperature grading preferably between the individual To align flank surfaces of the vortex generators 200 so that the turbulence that arises there is a good mixture with the appropriate amount of fuel.
- the fuel injection 7a, 7b can also Carry out over a large number of nozzles, depending on for the desired temperature grading and depending to the location of the individual vortex generators 200 within the flow cross-section of the annular combustion chamber 1.
- This annular combustion chamber can have several radial extensions superordinate rows of chambers exist, one row of chambers of which as a pilot stage to the others concentrically arranged Rows of chambers can be designed.
- a vortex generator 200, 201, 202 essentially consists of three freely flowing triangular surfaces. These are a roof surface 210 and two side surfaces 211 and 213. In their longitudinal extension, these surfaces run at certain angles in the direction of flow.
- the side walls of the vortex generators 200, 201, 202, which preferably consist of right-angled triangles, are fixed with their long sides on the channel wall 6 already mentioned, preferably gas-tight. They are oriented so that they form a joint on their narrow sides, including the arrow angle ⁇ .
- the joint is designed as a sharp connecting edge 216 and is perpendicular to each channel wall 6 with which the side surfaces are flush.
- the two side surfaces 211, 213 including the arrow angle ⁇ are symmetrical in shape, size and orientation in FIG. 3, they are arranged on both sides of an axis of symmetry 217 which is aligned in the same direction as the channel axis.
- the roof surface 210 lies against the same channel wall 6 as the side surfaces 211, 213 with a very narrow edge 215 running transversely to the flow channel.
- Its longitudinal edges 212, 214 are flush with the longitudinal edges of the side surfaces 211, 213 which protrude into the flow channel.
- the vortex generator 200, 201, 202 can also be provided with a bottom surface with which it is attached to the channel wall 6 in a suitable manner. Such a floor area is, however, unrelated to the mode of operation of the element.
- the mode of operation of the vortex generator 200, 201, 202 is the following: When flowing around edges 212 and 214, the Main flow converted into a pair of counter-rotating vortices, as schematically sketched in the figures.
- the Vortex axes lie in the axis of the main flow.
- the vortex strength or the number of twists increases, and the location of the vortex burst shifts upstream into the area of the vortex generator 200, 201, 202 themselves.
- these are both angles e and ⁇ due to structural conditions and determined by the process itself. Need to be adjusted these vortex generators only in terms of length and height, as detailed below under Fig. 6 for execution will arrive.
- the connecting edge 216 forms the two side surfaces 211, 213 the downstream edge of the vortex generator 200.
- the one running across the canal Edge 215 of roof surface 210 is thus that of the channel flow edge applied first.
- Vortex generator 201 is a so-called half "vortex generator" the base of a vortex generator shown in FIG. 6.
- Vortex generator 201 shown here is only one of the two Provide side surfaces with the arrow angle ⁇ / 2.
- the other Side surface is straight and aligned in the direction of flow.
- a vortex on the swept side is created here, like this is symbolized in the figure. Accordingly, it is downstream this vortex generator does not have a vortex-neutral field, but instead a swirl is imposed on the current.
- Fig. 5 differs from Fig. 3 in so far as here the sharp connecting edge 216 of the vortex generator 202 is the point which is affected first by the channel flow becomes. The element is therefore rotated by 180 °. How it can be seen from the illustration that the two have opposite directions Vortex changed their sense of rotation.
- Fig. 6 shows the basic geometry of one in a channel 5 built-in vortex generator 200.
- the influence on the ratio to be chosen of the two heights h / H is the pressure drop, that occurs when the vortex generator 200 flows around. It it goes without saying that with a larger ratio h / H the Pressure loss coefficient increases.
- the vortex generators 200, 201, 202 are mainly used when it comes to two currents with each other to mix.
- the main flow 4 for example as Hot gases, attacks the transverse one in the direction of the arrow Edge 215, or respectively the connecting edge 216.
- the secondary flow in the form of a gaseous and / or liquid fuel, which is enriched with a portion of supporting air at most (See Fig. 1) has a much smaller one Mass flow as the main flow. This secondary flow is in the present case downstream of the vortex generator the main flow is initiated, as shown in FIG. 1 in particular emerges well.
- the vortex generators 200 spaced around the circumference of a chamber of the channel 5 distributed.
- the vortex generators are also strung together in the circumferential direction, that no gaps are left on the channel wall 6.
- Figures 7-13 show other possible forms of introduction of fuel in the main flow 4. These variants can interact with each other and with a central Fuel injection, such as that shown in FIG. 1 emerges can be combined.
- the fuel in addition to channel wall bores 220, which are located downstream of the vortex generators, also injected via wall holes 221, which are immediately next to the side surfaces 211, 213 and in their Longitudinal extension in the same channel wall 6 are located on the the vortex generators are arranged.
- the introduction of the Fuel through the wall holes 221 gives the generated Whirl an extra impulse, which is the lifespan of the vortex generator extended.
- the fuel is fed through a slot 222 or injected via wall holes 223, both precautions immediately in front of the cross-canal extending edge 215 of the roof surface 210 and in the Longitudinal extension in the same channel wall 6 are located on the the vortex generators are arranged.
- the geometry of the Wall bores 223 or the slot 222 is selected such that the fuel at a certain injection angle into the Main flow 4 is entered and the re-placed vortex generator as a protective film against the hot main flow 4 largely shielded by flow.
- the secondary flow (See above) first of all via guides not shown through the channel wall 6 into the hollow interior of the vortex generators initiated. In this way, an internal cooling facility for the vortex generators created.
- the fuel is injected via wall bores 224, which is located directly within the roof area 210 behind and along the one running across the channel Edge 215.
- the vortex generator is cooled here more external than internal.
- the emerging secondary flow forms a flow against the roof surface 210 against the hot main flow 4 shielding protective layer.
- the fuel is injected via wall bores 225, which within the roof surface 210 along the line of symmetry 217 are staggered.
- the channel walls 6 are particularly good before the hot main flow 4 protected because the fuel is initially on the outer circumference the vertebra is introduced.
