Definitions
- the invention relates to a fuel injection device for a gas turbine combustion chamber with a liquid-cooled injector that a Has fuel guide tube with a surrounding coolant tube, which near the nozzle outlet opening in an annular space for the Coolant flows out or this directly surrounding the fuel guide tube Annulus forms.
- a Has fuel guide tube with a surrounding coolant tube which near the nozzle outlet opening in an annular space for the Coolant flows out or this directly surrounding the fuel guide tube Annulus forms.
- Liquid-cooled fuel injectors are particularly popular tiered gas turbine combustors are used, in which a so-called Main burner is temporarily switched off.
- a coolant preferably fuel
- this injector directed, d. H. into a wall area of the injection nozzle and of course without getting into the combustion chamber - returned again, which intensively cools the injection nozzle.
- the two The first-mentioned documents show such fuel injection devices with such liquid-cooled injectors, but these are fuel injectors relatively complex.
- the coolant tube directly and the fuel guide tube via an elbow in a nozzle holder are stored, one in the coolant tube in the nozzle holder provided first coolant line and in the hollow angle piece a fuel supply line opens.
- FIG. 1 shows a section through a fuel injection device according to the invention is shown.
- Fig. 2 shows the view X on the so-called.
- 3 the view X of the angle piece which will be explained later
- FIG. 4 shows the section A-A from FIG. 1.
- the fuel injector shown projects with its entirety with 1 designated injection nozzle into the combustion chamber, not shown ner gas turbine into it.
- the injection nozzle 1 is on a so-called Nozzle carrier 2 of the fuel injector attached.
- a fuel supply line 3 which into a in the injection nozzle 1 provided fuel guide tube 4 passes.
- the latter opens into a cavity 5 within a nozzle tip element 6, which has at least one nozzle outlet opening 7, via which the Fuel supplied via the feed line 3 and the guide tube 4 can get into the combustion chamber of the gas turbine.
- an end cap 8 is provided as usual, inside of which the fuel guide tube 4 is mounted.
- the nozzle tip element 6 and the end cap 8 or the Area thereof is to be cooled to prevent fuel, which is in this area in the guide tube 4, coked. Due to the high temperatures inside a gas turbine combustor namely in particular the area located near the nozzle outlet opening 7 an injector 1 such high temperatures that in the injector 1 Coke any fuel that is no longer being pumped would.
- coolant is now through the Injector 1 out u. a. through an annular space 9, which u. a. of the end cap 8 and the outside of the fuel guide tube 4 limited becomes. Coolant is guided through this annular space 9, specifically according to the arrows, which are provided with the reference number 15 elsewhere are, and fuel is preferably used again as the cooling liquid is coming.
- a coolant tube 10 is provided in the same from the annular space 9, which surrounds the fuel guide tube 4 at a distance.
- the Upper space segment 12a can supply coolant to the annular space 9 and are discharged again via the lower space segment 12b become.
- the upper space segment 12a has a feed channel 13 and the lower space segment 12b with a discharge channel 14 for each Coolant connected.
- the coolant flow is indicated by arrows 15 shown.
- Both the feed channel 13 and the discharge channel 14 naturally run also inside the nozzle holder 2 and are inside it essentially designed as coolant lines, which with the same reference numerals, namely 13, 14 are provided.
- the second coolant line 14 also surrounds a distance the fuel supply line 13 and is substantially concentric arranged to this. This is the second via an outlet opening 17 Coolant line 14 with a discharge flange provided on the nozzle carrier 2 18 connected for coolant. With its other end it ends this coolant line 14 is provided in a directly in the nozzle holder 2 Discharge channel 14, and is bypassed via this discharge channel 14 a so-called angle piece 19 connected to the lower space segment 12b.
- the angle piece 19 just mentioned serves on the one hand to accommodate the End cap 8 opposite end of the fuel guide tube 4 and connects, since it is hollow, this fuel guide tube 4 at the same time with the fuel supply line 3.
- the elbow 19 in Nozzle carrier 2 stored or pressed in as shown.
- the fuel injection device described is characterized by the elements mentioned through a particularly simple structure.
- the corresponding shaped nozzle carrier 2 which is divided in the area of level 20 can be formed, both the coolant lines 13 and 14 and the fuel supply line 3 are simply used.
- the elbow 19 can be used, which is the lower end the coolant line 14 leads. Then you can in this elbow 19 the fuel guide tube 4 are inserted, after which the partition element 11 and the coolant tube 10 are used.
- only the end cap 8, with the nozzle tip element 6, and a shielding cap 21 can be mounted.
- the space segments 12a, 12b here take the form of cylinder segments after the fuel guide tube 4 is straight.
- a particularly simple shape of the partition element 11 whereby by a suitable choice of its cross-sectional area also that the cheapest volume or the cheapest contour of the room segments 12a, 12b is adjustable.
- a seal carrier 22 is also provided, which has ring seals 23 is provided, in particular around an undesired outflow of cooling liquid to prevent in an area away from the discharge flange 18.
