Aug. 5, 1969 P. J. CLARK SUPPORTS FOR FUEL BURNERS Filed Aug. 17, 1967 lllllllllllllll United States Patent US. Cl. 6039.74 2 Claims ABSTRACT OF THE DISCLOSURE A gas turbine engine burner for gas or liquid fuel has an inner passage for liquid fuel surrounded by an annular passage for gas, the burner being mounted in the engine by part-spherical bearings, that at the downstream end being mounted to permit of lengthwise movement of the burner end in the engine to accommodate expansion.
This invention relates to fuel burners and to support means therefor, the object being to provide such a burner in a convenient form.
In accordance with the present invention a burner is provided with means for supporting it in a structure at two spaced positions lengthwise thereof, comprising a pair of part spherical bearings at said positions respectively, one of the bearings being connected to the burner so as to permit of lengthwise movement of the burner relatively to the structure.
The invention will now be described with reference to the accompanying drawings, in which FIGURE 1 illustrates in cross-section a burner supported in a gas turbine engine in a manner in accordance with the invention, and FIGURE 2 is an enlarged view of one end of the burner.
The burner illustrated is arranged for the supply of liquid fuel or alternatively gaseous fuel to combustion apparatus of a gas turbine engine. The engine shown has an annular combustion chamber 1 defined by inner and outer walls 2, 3 made up from a plurality of interconnected sections. The chamber 1 is enclosed within an annular air jacket which is defined by inner and outer walls 4, 5. There is also an outer casing 6 to the interior of which air is admitted at the upstream end in a manner not shown.
The upstream ends of the air jacket walls 4, are spaced to provide a path for the entry of a proportion of the air within the outer casing and some of this can enter the chamber, as Well as through a swirler 8 at the upstream end of the combustion chamber 1. Attached to the swirler 8 is an annular flare plate 9 forming the upstream wall of the combustion chamber 1. This is attached at its inner and outer edges to the walls 2, 3 of the chamber 1, and there is also an air entry nose piece 9a secured by its inner and outer edges to the combustion chamber walls 2, 3.
Supported upon the outer casing 6 and also within the swirler 8 are a plurality of equi-angularly spaced elongated burners, one of which is shown in cross-section in the drawing.
The burner comprises an inner tubular member 10 through which liquid fuel is intended to be supplied, and inner and outer concentric tubular parts 11, 12 between which gaseous fuel is intended to be supplied. The liquid fuel from the member 10 can be discharged into the combustion chamber 1 from a nozzle 13, and the gaseous fuel can be discharged into the combustion chamber 1 through a plurality of angularly spaced inclined openings 14 formed in a part 15, surrounding the nozzle 13. This part 15 also serves to interconnect the inner and outer parts 11, 12 at their downstream ends.
The face of the member 15 between the nozzle 13 and the openings 14 is provided with a plurality of slots 16 arranged at inclined angles to a radial plane at this face, these slots 16 communicating with the space defined between the inner tubular member 10 and the inner tubular part 11. Air enters this space through a radially extending opening 17, this opening being formed in a body 18 to which the upstream ends of the parts 11, 12 are connected. The air is given a swirling motion as it flows through the slots 16 into the combustion chamber 1.
Through the body 18 extend a plurality of angularly spaced passages 19, which are off-set from the axis of the body which is concentric with the member 10 and parts 11, 12. The passages 19?, one of which is shown, communicate through drillings 19a with an annular gallery 10 formed in a part 21 connected to the body 18, the outer boundary of the gallery being defined by a part 22 having an inlet 23 for gaseous fuel. The opposite ends of the passages 19 communicate with the space defined between the inner and outer tubular parts 11, 12.
It is to be noted that the inner tubular member 10 and the inner and outer tubular parts 11, 12 are sufliciently long to afford a lengthwise spacing between the body 18 r and the member 15 of approximately eleven inches in the present example, and the region surrounding the outer tubular part 12 is that to which the air is admitted. The opening 17 also communicates with this region.
The swirler 8 fixed in the flare plate 9 of the engine forms a support for the downstream end of the burner, support being through a part-spherical bearing member 24, which engages the external cylindrical surface of the member 15 to permit lengthwise movement of the burner through the swirler 8 in order to accommodate lengthwire expansion pf the burner.
The body 18 has a part-spherical bearing portion 25 engaging a part 26 mounted by a locking nut 27 in an externally flanged sleeve 28 mounted on the outer casing 6 of the engine. A compressible seal 29 is provided between the body 18 and the part 26 which is held in place by the nut 27. This nut also holds the bearing portion 25 against a further complementarily shaped part 30 abutting against a shoulder of the sleeve 28. This part of the outer casing 6 is substantially upstream from the combustion chamber 1, as shown.
The sleeve 28 is mounted on the casing 6 by pins 31 and bolts (not shown), the pins being secured in the casing 6, and the sleeve 28 is provided with substantial clearance over the body 18 so that limited movement of these parts about the part spherical bearing can take place. A pin 32 engaging a slot 33 in the sleeve 28 prevents relative angular movement between the sleeve 28 and the body 18.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. A burner assembly comprising an elongated burner providing passages for fuel to be ejected, support means whereby the burner can be supported in a structure, said support means comprising a part spherical bearing disposed between the burner and the structure near one end of the burner, said bearing being fixed to the burner as well as to the structure, and a further part spherical bearing disposed between the burner and the structure near the other end of the burner, the further bearing being fixed to the structure and connected to the burner to permit relative movement lengthwise of the burner to take place.
2. A burner assembly as claimed in claim 1 in which a swirler is mounted in the structure, said further part spherical bearing being disposed between the swirler and 3 4 the burner, to permit relative lengthwise movement be- 2,965,303 12/1960 Jackson 239-132 tween the burner and the swirler and structure. 3,159,971 12/1964 Moebius et a1. 6039.74 3,320,744 5/1967 Blakely et a1. 60-3974 References Cited 2,675,864 4/1954 Seaver 1226.5 1 2,907,527 10/1959 Cummings 239135 431-139
