Definitions

  • the invention relates to a heat shield, in particular for arrangement in a combustion chamber of a gas turbine, and to a heat shield element, which is used as part of the heat shield and on a combustion chamber and a gas turbine comprising the combustion chamber, wherein the combustion chamber lined at least partially with such a heat shield is.
  • heat shields are used, which must withstand hot gases of 1000 to 1600 degrees Celsius.
  • gas turbines such as those used in power-generating power plants and in aircraft engines, have correspondingly large surfaces to be shielded by heat shields in the interior of the combustion chambers.
  • the heat shield must be composed of a plurality of individual, generally ceramic heat shield bricks, which are spaced from each other with a sufficient gap attached to a support structure by means of holding elements. This expansion gap offers the heat shield bricks, which can also be called heat shield elements, sufficient space for the thermal expansion.
  • the heat shield elements Due to its function, the heat shield elements have a hot side which can be acted upon with hot gas, an opposite (not necessarily parallel to the hot side) cold side and peripheral sides which connect the hot side to the cold side, wherein the heat shield element with the cold side points to a support structure of the heat shield the support structure is fastened.
  • the considered heat shield element generally has a flat planar shape.
  • the cold side can be a substantially planar surface which rests on the support structure when the heat shield element is fastened to the support structure.
  • the support structure of the generic heat shield for example, the lining at least partially radially inward lining and be formed as part of the combustion chamber wall.
  • cooling air is again used, which is distributed over the fastening grooves.
  • the distribution of the cooling air is not always optimal.
  • the larger in free cross-section fastening grooves with locally different gap widths between the heat shield elements in individual cases lead to insufficient flushing of all gaps with cooling air due to the exit to large amounts of cooling air in larger columns.
  • either early damage to the support structure or the fasteners is accepted - with the result of shorter maintenance intervals - or it is the amount of cooling air increases, resulting in a - albeit slightly smaller - efficiency of the gas turbine.
  • the object of the present invention is therefore to further optimize the distribution of cooling air to the gaps between the heat shield elements.
  • the generic heat shield element is used as intended in a generic heat shield, wherein the heat shield comprises a plurality of heat shield elements.
  • the heat shield serves as heat protection in a combustion chamber, in particular a combustion chamber of a gas turbine.
  • the heat shield comprises, in addition to the heat shield elements, a support structure in which, in the generic manner, at least two fastening grooves arranged at a distance from each other run parallel to one another.
  • the fastening grooves extend in a longitudinal direction, with this not necessarily - although the rule - a straight line is to be understood.
  • the longitudinal direction may also have a lying in a plane arcuate course. That the mounting grooves extend either straight or following the curvature of the support structure with an arcuate course.
  • the fastening grooves in this case have a substantially constant groove width and advantageously a constant cross-section - with the exception of, for example, openings for introducing the fastening means.
  • the fastening grooves are to be designed taking into account the intended fastening means, so that they can be inserted into the fastening grooves and held therein.
  • the generic heat shield elements are attached to the support structure in the generic heat shield.
  • the heat shield elements are fastened in a manner that can be released in rows on the support structure, essentially over the entire area, leaving expansion gaps between the heat shield elements.
  • the heat shield element has a hot side facing the combustion chamber interior and an opposite cold side facing the support structure.
  • the hot side with the cold side is circumferentially connected via peripheral sides, with two opposite first peripheral sides and to the first peripheral sides alternately two opposite second circumferential sides are present.
  • the orientation of the second circumferential sides corresponds to the longitudinal direction. That is, these run parallel to the fastening grooves.
  • the object is achieved in a heat shield element of the type mentioned above in that two web-shaped ribs are arranged on the cold side of the heat shield element.
  • the two ribs are spaced apart from one another and extend in the longitudinal direction parallel to each other along the cold side and spaced parallel to the second circumferential sides. It is thus transverse to the longitudinal direction at least on both sides of the two ribs and between the two ribs, an area of the cold side.
  • the ribs are connected in a straight line on the cold side.
  • the ribs are arranged at a distance from the fastening grooves.
  • the rib width must be at least slightly smaller than the groove width.
  • This inventive design of the ribs allows the mounting of the heat shield element according to the invention on the support structure, wherein the two ribs protrude when arranged on the support structure heat shield element in the two mutually parallel mounting grooves, which are arranged in the support structure.
  • the heat shield element can thus be arranged with the cold side on the support structure, wherein the ribs protrude into two fastening grooves of the support structure.
  • the ribs in this case fill at least part of the volume in the fastening grooves out.
  • the free cross section of the fastening grooves below the cold side of the heat shield element reduces around the ribs projecting into the fastening grooves.
  • the reduced cross-section improves the distribution of the cooling air, so that an uneven distribution of the cooling air through individual gaps between the heat shield elements is counteracted. On the one hand, this improves the cooling effect and, on the other hand, reduces the consumption of cooling air that is otherwise required to ensure that sufficient cooling air is supplied even in poorly ventilated areas.
  • the use of a single heat shield element according to the invention in the heat shield according to the invention already proportionally improves the cooling air distribution.
  • the heat shield among the plurality of heat shield elements comprises one or more heat shield elements according to the invention, wherein as many heat shield elements as possible according to the installation possibilities are used in an advantageous manner.
  • the heat shield element can be assembled in one piece as well as in several parts and consist of different materials. With regard to the use of the embodiment according to the invention with the back in the mounting grooves projecting ribs, however, it is particularly advantageous if the heat shield element consists of a ceramic material and is made in one piece together with the ribs. An example of a layered structure with firmly interconnected or merging ceramic materials with different properties is included here.
  • the ceramic heat shield elements can be produced by means of a casting mold, wherein the solidified green compact is removed from the mold and then fired in a sintering process. For attaching the ribs thus only a correspondingly shaped mold is needed. The Otherwise, the production process may be the same as the conventional process.
  • the two ribs are arranged symmetrically to a median plane of the heat shield element. This reduces the risk of H contemplatgaseinzuges in a gap surrounding the heat shield element, since the symmetrical arrangement of the ribs or the associated here substantially symmetrical structure of the heat shield element leads to a uniform distribution of the cooling air and locally insufficient care gap regions avoids.
  • the width of the ribs may for example be selected slightly narrower than the width of the fastening grooves. This allows for easy installation of the heat shield elements and fills as much volume between the stone holders. It is advantageous if the rib width of the ribs corresponds to at least 75% of the groove width of the fastening grooves. Particularly advantageous is a rib width of 90% of the groove width.
  • the embodiment of the ribs transversely to the longitudinal direction is initially insignificant, wherein the shape is both simple and advantageous, when the ribs extend on the top thereof in a straight line transversely to the longitudinal direction in a straight line.
  • This embodiment of the invention relates to a quadrangular basic shape of the heat shield element, wherein the fastening means (preferably four) engage in pairs opposite holding portions in the at least one recess.
  • the recess may, for example, be a groove running parallel to the cold side on the peripheral side.
  • a fastening means is arranged, which is arranged with a fixing portion in the respective mounting groove and engages with a holding portion in a recess of a peripheral side of the heat shield element, wherein the rib that at least partially fills the volume extending between the two fastening means in the fastening groove.
  • the fastening means may be fastening bolts, which rest with a bolt head on an inserted into the recess retaining plate.
  • a recess for example, fastening bore or fastening groove
  • the bolt shank can extend in the direction of the support structure.
  • the fastening bolt can be screwed into a fastening means arranged in the support structure, which comprises a cup spring package and holds the bolt resiliently.
  • This type of attachment is particularly suitable for a dummy stone, which must be attached to the support structure as the last of the series in a normal to the support structure facing assembly movement.
  • stone holders are preferably used as fastening means, which can be inserted into the fastening grooves in the support structure and detect the heat shield element in a spring-locking manner.
  • These stone holders comprise an elongate base plate, which engages with a widening in a groove-shaped widening of the fastening groove. As a result, the base plate is secured against being pulled out of the fastening groove and can be displaced along the fastening groove.
  • On the base plate a holding portion is arranged, which protrudes from the mounting groove and engages in the peripheral surface of the heat shield element.
  • the stone holder is made of a metallic material and holds the heat shield element resiliently in position.
  • the fastening grooves serve for fastening heat shield elements by means of a mounting movement running parallel to the fastening groove.
  • the heat shield elements are in this case attached to slidably held in the mounting grooves stone holders and pushed in their assembly to the last stone of the series.
  • Four pairs of oppositely arranged stone holders hold a heat shield element.
  • two stone holders of one side are additionally fixed in the end position of the heat shield element. Since the heat shield element row is generally circumferential, a so-called dummy stone is inserted at at least one position, which is fastened in a row in the row in a direction normal to the supporting structure. For example, by means of four pairs of oppositely arranged screw, which are screwed into the groove bottom of the mounting grooves.
