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.
- EP 0 689 006 A1 also refers to WO 94/08179.
- Liquid-cooled fuel injectors are particularly popular tiered gas turbine combustion chambers are used, in which a so-called Main burner is temporarily switched off.
- a coolant preferably fuel
- the two above-mentioned documents show such fuel injection devices such liquid-cooled injectors, but these are fuel injectors relatively complex.
- the solution to this problem is characterized in that within the Coolant pipe upstream with respect to the fuel flow direction of the annular space a partition wall element surrounding the fuel guide tube is provided, which is the interior of the coolant tube divided into two room segments, the first room segment with a feed channel and the second space segment with a discharge channel for the coolant is connected.
- 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 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. from 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 Annulus between the coolant tube 10 and the fuel guide tube 4 by a so-called partition element 11 in two room segments 12a, 12b divided, as can be seen in particular from FIG. 4.
- the Upper space segment 12a can supply coolant to the annular space 9 and are discharged again via the lower space segment 12b will.
- 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 via an outlet opening 17 second coolant line 14 provided on the nozzle carrier 2 Discharge flange 18 connected for coolant. With its other end This coolant line 14 opens into a directly in the nozzle holder 2 provided discharge channel 14, and is below this discharge channel 14 Bypassing a so-called elbow 19 with the lower space segment 12b connected.
- 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.
- the nozzle outlet must 7, or several of them, which can be arranged in a ring, also not be designed as here, but it can be done with one Outlet opening 7 also produces a conically shaped single fuel jet will.
