Definitions

  • the invention relates to an exhaust duct for gas turbines according to the preamble of claim 1.
  • Stationary gas turbines with a high output usually have an axial outflow housing which is connected to an exhaust gas chimney via an exhaust line.
  • the speed of the exhaust gas flow which is of the order of 100 m / s at the turbine outlet, must be decelerated to about 50 m / s in the exhaust line, since otherwise the silencer required to reduce noise pollution can be destroyed.
  • such a delay in the flow rate is required to reduce the leakage losses and to avoid inadmissible noises at the mouth of the exhaust gas chimney.
  • a low-loss deceleration of the flow speed is problematic with reasonable dimensions of the exhaust gas section, since the very high volume flows require large flow cross sections and also a deflection of the exhaust gas flow from the axial to the vertical direction is required.
  • the muffler is either arranged axially behind the gas turbine or inserted vertically into the exhaust gas chimney. In the former case, a very long axial transition piece is required to delay the flow velocity to a level that is conducive to the muffler. If this space is not available, flow resistances have to be installed to slow down and equalize the speed, but these generate additional losses.
  • the invention is therefore based on the object of creating an exhaust gas duct for gas turbines, the exhaust gas path of which allows a low-loss deceleration of the flow velocity while requiring little space.
  • the overall 'entire exhaust path is formed solely by a deflection which is substantially horizontally oriented first diffuser portion and a vertically oriented second diffuser section acts by a total of as a diffuser, and therefore dispensing with transitional and intermediate pieces a low-loss delay Flow rate causes.
  • the prerequisites for a detachment-free flow through the deflection piece and for the effectiveness of the vertically oriented second diffuser section are hereby ensured by the grille arranged in the deflection piece for uniform deflection of the exhaust gas flow.
  • the partial lengths of the first and second diffuser sections are freely selectable, so that the exhaust gas route can be carried out to the respective locations with little effort Liche space can be adjusted.
  • the first diffuser section and the second diffuser section are formed from a single circular cone diffuser by angled miter cut. This enables an extremely economical production of the deflection piece.
  • the grille for deflecting the exhaust gas flow is arranged in an intermediate piece with an elliptical cross section and that the intermediate piece is welded into the miter joint between the two diffuser sections.
  • the intermediate piece with the grille can be finished with the two diffuser sections before welding, which in particular makes it easier to weld in the individual deflection plates of the grille.
  • Substantially horizontally oriented first diffuser section is inclined relative to the horizontal in such a way that the deflection piece can be laid over the hallway.
  • the exhaust duct begins with a part shown only th axial discharge housing 1 of a gas turbine, from which the exhaust gas flow indicated by arrows 2 emerges in the horizontal direction.
  • a low-loss deceleration of the exhaust gas flow 2 is achieved in the first diffuser section 31, the expansion angle of which is designated by a.
  • the first diffuser section 31 is directed somewhat upwards in order to avoid laying under floor F. The deviation from the horizontal indicated by the angle y must, however, be slight, since otherwise a flow separation could already occur at the beginning of the first diffuser section 31.
  • the uniformity of the deflection of the exhaust gas flow 2 with minimal deflection losses is ensured by a sufficient number of deflection plates of the grille 321.
  • the intermediate piece 32 with the grating 321 is then adjoined by a second diffuser section 33 of the deflection piece 3, which begins with an inclined section and is oriented vertically.
  • this second diffuser section 33 the widening angle a of which corresponds to the widening angle a of the first diffuser section 31, a further low-loss deceleration of the exhaust gas stream 2 is achieved.
  • the second diffuser section 33 is adjoined by a vertical exhaust gas chimney, designated overall by 4, which, seen from the bottom up, into a cylindrical silencer section 41, a conical transition piece 42 and a cylindrical chimney part 43 is divided.
  • a muffler 5 is arranged, which consists of a number of vertical plates serving as muffler elements.
  • FIGS. 2 to 4. The individual steps in the manufacture of the deflection piece 3 are shown in FIGS. 2 to 4. 2, a single circular cone diffuser K is assumed, which is divided by an oblique cut S into a miter dimension into the first diffuser section 31 and the second diffuser section 33.
  • the miter angle is denoted by ß.
  • the oblique cut S gives the two diffuser sections 31 and 33 oblique cut surfaces in the form of ellipses which, according to FIG. 3, also match one another when the second diffuser section 33 is rotated about its axis by an angle of 180 ° .
  • the intermediate piece 32 with the grid 321 then only needs to be welded into the miter joint between the two diffuser sections 31 and 33 according to FIG. 4.
  • the partial lengths of the two diffuser sections 31 and 32 can be adapted to the local conditions. Since degrees of pressure recovery, flow separation criteria and total pressure losses of circular cone diffusers - depending on the length and extension angle - are known, the exhaust gas section formed by the deflection piece 3 as a circular cone diffuser can be calculated and optimized.
