Definitions

  • the invention relates to a heat exchanger, in particular for systems operated with large load and / or temperature changes, for example as cooling air coolers for gas turbines, with pipes for separating the heat-emitting medium, in particular air, and the heat-absorbing medium, in particular water, the heat exchange taking place in countercurrent , which are arranged as flow channels for the heat-absorbing medium pipes running in a meandering shape between an inlet manifold and an outlet manifold and the heat-emitting medium flows around these meandering pipes.
  • the cooling of gas turbine blades usually takes place by means of an air flow, which is often branched off from the compressed combustion air for the gas turbine combustion chamber as a partial air flow.
  • the heat supplied during the compression of this partial air flow must be extracted from the air flow in a cooling air cooler before being fed to the gas turbine blades. Due to frequent starting and stopping as well as the high pressure and temperature differences, this heat exchanger is exposed to extreme alternating loads, which can lead to premature failure of the heat exchanger.
  • a cooling air cooler of the type described in the opening paragraph is known from EP-OS 0 203 445.
  • the inlet and outlet manifolds are rigidly connected to the clean gas inlet and clean gas outlet lines, so that alternating load voltages can only be insufficiently compensated.
  • Another cooling air cooler for gas turbines is known from DE-OS 41 42 375.5.
  • massive tube plates serve to separate the air-filled chambers from a space filled with the heat-absorbing medium.
  • the air to be cooled is passed through pipes which connect the two solid pipe plates arranged at the upper and lower ends of the heat exchanger and are rigidly fixed in them.
  • one of the solid tube plates is formed by one-sided clamping in such a way that it can compensate for pressure and temperature stresses to a certain extent.
  • the outer jacket of the heat exchanger is equipped with bellows expansion joints to dampen length changes.
  • the object of the invention is to further develop a heat exchanger of the type mentioned at the outset in such a way that it reliably and reliably compensates for the frequent and rapid load changes and the associated pressure and temperature fluctuations and, moreover, is inexpensive to manufacture.
  • the invention proposes that the collecting tubes penetrate an outer jacket of the heat exchanger on both sides, the collecting tubes being connected pressure-tight to the outer jacket on the inlet and outlet sides and being guided at the opposite end into a receiving space connected to the outer jacket in a pressure-tight manner.
  • This elastic mounting of the header pipes enables additional compensation of the load alternating voltages that occur, since the header pipes are not fixed at least on one side in the outer jacket of the Heat exchanger are clamped. Instead, the manifolds can expand into the receiving space. Such an expansion in the transverse direction of the heat exchanger does not cause any additional stresses in these tubes due to the elastic arrangement of the heat exchanger tubes.
  • Due to the passage of the header pipes through the outer jacket of the heat exchanger it is possible that in the event of pipe leaks, plugging or blinding of individual heat exchanger pipes from the outside is possible in a simple manner.
  • the flow channels for the heat-absorbing medium as meandering heat exchanger tubes arranged between two header tubes, compensation of the pressure and temperature fluctuations that occur can be achieved in a particularly simple and effective manner, since the meandering coil bundle acts as a whole as a large spring.
  • the back and forth heat exchanger tubes can absorb the occurring load changes without the risk of impermissibly high voltage conditions.
  • the meandering tubes are surrounded by an inner housing which is open at the end and connected on the inlet side to the inlet connector for the heat-emitting medium and which forms a flow channel for the heat-emitting medium.
  • an inner housing which is open at the end and connected on the inlet side to the inlet connector for the heat-emitting medium and which forms a flow channel for the heat-emitting medium.
  • a circumferential space is formed between the outer jacket of the heat exchanger and the inner housing enclosing the pipes and the outlet connection for the heat emitting Medium is arranged near the outlet manifold. The formation of the space between the outer jacket and the housing prevents direct heat conduction to the outer jacket of the heat exchanger.
  • This insulation of the outer jacket against the high inlet temperatures of the Medium to be cooled can be strengthened in that the outlet connection is arranged near the outlet manifold and thus also close to the inlet connection for the heat-emitting medium, so that the medium cooled by the flow along the heat exchanger tubes before leaving the heat exchanger covers the entire space between the housing and must flow through the outer jacket, which in turn contributes to the insulation of the outer jacket.
  • the surfaces in contact with the heat-emitting medium are made of austenitic steels.
  • the heat exchanger can be operated with water as the heat-absorbing medium as a preheater, evaporator, superheater, preheater with evaporator, evaporator with superheater or preheater with evaporator and superheater. Because of the various possibilities with which the heat exchanger according to the invention can be operated, it can be used in a variety of ways, depending on the respective pressure and temperature conditions, without having to change over.
  • FIG. 1 and 2 schematically show a heat exchanger 1, consisting of a welded outer jacket 2 with an inlet connector 3 and an outlet connector 4 for the heat-emitting medium and an inlet header 5 and an outlet header pipe 6 for the heat-absorbing medium, the inlet header pipe 5 and the outlet header pipe 6 being connected to one another via meandering pipes 7.
  • these tubes 7 are surrounded in the axial direction by a housing 8 which is open at both ends and connected to the inlet connector 3 on the inlet side.
  • the arrows shown in FIG. 2 illustrate the flow pattern of the heat-emitting and heat-absorbing medium in the heat exchanger 1.
  • the heat-emitting medium flows through the inlet connection 3 into the heat exchanger 1 and is through the housing 8, which forms a flow channel for the heat-emitting medium, guided from top to bottom along the tubes 7, which are filled with a heat-absorbing medium and flow from bottom to top.
  • the now cooled medium is deflected in the illustrated embodiment through a bottom 9 of the heat exchanger 1 and flows into an intermediate space 10 formed between the outer jacket 2 of the heat exchanger 1 and the housing 8 before the medium passes over the heat exchanger 1 leaves the outlet port 4 again.
  • the outlet port 4 is arranged in the illustrated embodiment near the outlet manifold 6, so that the cooled medium flows as far as possible along the entire axial extent of the outer shell 2 and thus insulates it from the heat of the uncooled inflowing heat-emitting medium.
  • the heat-absorbing medium in particular water, flows through the inlet manifold 5 into the heat exchanger 1 and flows from the bottom upwards through the meandering tubes 7 before it flows out of the heat exchanger 1 again after entering the outlet manifold 6.
  • the heat-emitting and the heat-absorbing medium are led to the particularly effective heat exchange in cross-countercurrent.
  • both the inlet and outlet manifolds 5, 6 and the thin-walled tubes 7 connecting the manifolds 5, 6 are elastically suspended and the manifolds 5, 6 are thin-walled compared to the tube plates known from the prior art.
  • the elastic suspension of the inlet manifold 5 and the outlet manifold 6 is that the manifolds penetrate the outer jacket 2 of the heat exchanger 1 on both sides, the manifolds 5, 6 being pressure-tightly connected to the outer jacket 2 on the inlet and outlet sides and at the opposite end are guided in a pressure-tight connection with the outer casing 2.
  • This elastic integration of the collecting tubes 5, 6 into the outer jacket 2 of the heat exchanger 1 enables the collecting tubes 5, 6 to compensate for the stresses that occur during the load changes that occur.
  • the pipes 7 are arranged in a meandering manner between the inlet manifold 5 and the outlet manifold 6, so that the entire bundle of tubes 7 is designed to be resilient overall and can thus effectively compensate for the stresses that occur.
