Definitions

  • the invention relates to a combustion chamber for a gas turbine with a mixing housing and a gas turbine with such a combustion chamber.
  • the mixing housing When mounting a mixing housing of a gas turbine, the mixing housing is first mounted in the combustion chamber to the flame tube.
  • the mixing housing must be precisely aligned so that the lower mixing housing connection fits into the connection of the inner housing of the fuselage turbine.
  • the mass, shapes and positions of the mixing housing and the inner casing of the fuselage turbine of a gas turbine have such large variances due to production that the mixing housing can not readily be positioned to the inner casing of the fuselage turbine.
  • the position of the inner housing is transferred to a template.
  • the mixing housing can be made with the cooling air ring and aligned at the inner housing position in the area of the pressure jacket flange.
  • Fig. 2 a template for positioning a mixing housing according to the prior art is shown.
  • the template 11 is fastened by six screws 21 on the pressure jacket flange 10 surrounding the mixing housing.
  • the cooling air ring 6 is aligned with the template 11.
  • Fig. 3 represents a detailed view of two alignment points between the template 11 and the cooling air ring 6.
  • the grooves 23 of the template 11 receive the pins 22 of the cooling air ring 6 and thus define the position of the cooling air ring 6.
  • the cooling air ring can be welded to the mixing housing.
  • a combustion chamber with a Mischgegäuse known, which in turn has a centering device.
  • the invention has for its object to provide an advantageous mixing housing arrangement and a gas turbine with an advantageous mixing housing arrangement available.
  • a combustion chamber according to the invention has a mixing housing with an outer housing surrounding the mixing housing, wherein the mixing housing is adjustable relative to the outer housing.
  • the mixing housing is provided with an adjusting device for adjusting the mixing housing relative to the outer housing.
  • the combustion chamber has an adjusting device which comprises a bolt, a pressure plate and a wedge disk.
  • the contact surfaces between the pin and the wedge disk and between the pin and the pressure plate can be made spherical be such that the flange portion of the bolt between the counterparts can be moved on a spherical surface.
  • the mixing housing moves with it, but maintains its concentric position to the flame tube.
  • the cooling air ring is welded to the mixing housing and then aligned with the inner housing position.
  • the spherical surface between the pin and the pressure plate enables quick and cost-effective retrofitting of existing machines. Due to the optimized dimensions of the bolt, even in the worst case, no critical shifts of the mixing housing during operation occur.
  • the adjustment is thus based on the variable position of the bearing bolts. This eliminates the individual transmission of the inner housing position of a gas turbine by means of a template, and it can be used, the statistical means of the inner housing position.
  • the bolts can be eccentrically installed, so that a height adjustment of the mixing housing is possible.
  • the bolts on the head can each have an eccentric bore with an eccentric pin inserted therein.
  • the bolts can also be slidably mounted in parallel vertically and horizontally to the outer housing. As a result, a gap adaptation of the mixing housing to the flame tube is possible.
  • the mixing housing can be tilted about the pin axis, whereby a further flexibility of the mixing housing is achieved.
  • the bolt can be located in a flange tube, which is arranged in the outer housing.
  • the flange tube can in particular be widened to a slot. This allows a horizontal adjustment of the mixing housing. The vertical adjustment is then also possible by tilting the mixing housing about the pin axis and the use of the eccentric.
  • the adjusting device can also be designed as a guide and rail system with the aid of which the mixing housing can be positioned more accurately. In this case, an arrangement of adjustable bolts is not required.
  • a gas turbine according to the invention comprises a combustion chamber according to the invention.
  • the combustion chamber may comprise a cooling air ring fixed to the mixing housing and facing the inner housing.
  • the gap between the inner housing and the cooling air ring is then advantageously 3 to 3.5 mm.
  • Fig. 1 shows first a combustion chamber 1 of a gas turbine with an outer housing, which is called pressure jacket 18, sometimes called combustion chamber jacket, executed, and with a disposed within the outer housing or pressure jacket 18 flame tube 2. Within the pressure jacket 18 are also a mixing housing 4 and a at the mixing housing 4 fixed cooling air ring. 6
  • the flame tube 2 extends vertically and is located in the upper region of the arrangement shown. It absorbs the flames generated by the burner 3 located at the upper end of the pressure jacket.
  • the conical and curved mixing housing 4 connects, which leads the combustion gases to an inner casing 8 of a fuselage turbine (not shown).
  • the cooling air ring 6 adjoins the mixing housing 4, which cools the transition between the mixing housing 4 and the inner housing 8.
  • the mixing housing 4 is fastened by two bolts 12 on the pressure jacket 18.
  • the bolts 12 are located in flange tubes 20 with Flanschrohrlteilsachsen 19, which are arranged in the pressure jacket 18, namely in the vicinity of a support 11 in the region of the lower part of the mixing housing 4. This go the Flanschrohrlteilsachsen 19 (see Fig. 5 ) through the intersection of a flame tube longitudinal axis 7 and an inner housing longitudinal axis 9 (s. Fig. 1 ).
  • the flange tubes can be arranged with their longitudinal axes 19 perpendicular to the plane defined by the flame tube longitudinal axis 7 and the inner housing longitudinal axis 9 surface. Within a horizontal elongated hole, the bolts and thus the mixing housing can then be moved well in the direction of the extended inner housing longitudinal axis 9.
  • the flanged pipes can but equally well positioned at any other location on the outer surface of the pressure jacket 18, but then not the optimal displaceability along the inner housing longitudinal axis 9 is achieved.
  • Fig. 4 shows an enlarged detail view X of the area within the pressure jacket flange 10 in FIG Fig. 1 , Within the Druckmantelflansches 10 of the pressure jacket 18 are the connection points between the mixing housing 4 and the cooling air ring 6 and between the cooling air ring 6 and inner housing 8.
  • the cooling air ring 6 is welded at one end to the mixing housing 4. The other end of the cooling air ring 6 is inserted into the connection cross section of the inner housing 8.
  • Fig. 5 is the adjustable arrangement between mixing housing 4, pressure jacket 18, and one of the two bolts 12 (see Fig. 1 ).
  • the bolt 12 is received at the unscrewed end in a mixing housing sleeve 5, while the flange 17 is located within the flange tube 20 of the pressure jacket 18.
  • the mixing housing sleeve 5 is located on the outside of the mixing housing 4.
  • the bolt 12 can be fixed to the flange 17 by a plurality of circumferentially distributed screws 16 on the pressure jacket 18.
  • the wedge plate 14 which is annular and surrounds the pin 12.
  • the wedge disk 14 has a spherical surface 15 on the surface adjoining the bolt.
  • the bolt also has a spherical surface 15 on the flange surface, which rests on the wedge disk in the installed state.
  • the concave sides of the two resting on each other spherical surfaces 15 show for Mixing housing 4. This results in the dissolved state of the bolt 12 a rotatable along the spherical surfaces bearing of the bolt 12 between Andschreibblech 13 and wedge disk 14th
  • the two spherical surfaces 15 between Andschreibblech 13, bolts 12 and wedge disk 14 allow the mixing housing 4 via the bolt 12 in its position relative to the inner housing 8 (see Fig. 4 ) of the hull turbine is adjustable.
  • the mixing housing 4 can be rotated by the bolts 12 with the bolt longitudinal axis 24 by the angle a relative to the Flanschrohrlteilsachse 19.
  • the mixing housing is rotated by ⁇ 0.15 °. After adjusting the mixing housing tighten the screws of the bearing bolts. The bolts and thus the mixing housing are then held in position by frictional force.
  • a bore 26 for screwing a mounting rod In the flange 17 of the bolt 12 is also a bore 26 for screwing a mounting rod.
  • Fig. 6 illustrates a single view of the bolt 12.
  • the bolt 12 has on both sides of its flange spherical surfaces 15 (s. Fig. 5 ).
  • the borehole can also be expanded to a slot.
  • the diameter A of the bolt flange holes (about 25 mm) is larger as the diameter B of the flange holes of the wedge plate 14 (s. Fig. 7 ) and the pressure plate 13 (s. Fig. 8 ), so that the fastening screws 16 of the bolt 12 have sufficient clearance during the movement of the bolt for adjusting the bolt position.
  • Fig. 7 shows a single view of a wedge plate 14 as already in the assembly in Fig. 5 shown.
  • the wedge disk 14 has a spherical surface 15 only on the side which rests on the flange of the bolt 12 during assembly to allow adjustment of the bolt 12.
  • Fig. 8 shows a single view of a Andschreibblechs 13, which is already in the assembly in Fig. 5 is shown.
  • the pressure plate 13 also has only on the side which rests on the flange of the bolt 12 in the assembly, a spherical surface 15 in order to allow adjustment of the bolt 12.
