Definitions

  • the present invention relates to a saturated steam turbine system according to the preamble of the claim.
  • the steam coming from the high-pressure turbine is dried and then overheated.
  • the steam can then be expanded in the low-pressure turbine until final wetting.
  • the steam is usually dried and superheated in combined water separator reheaters.
  • the reheaters are designed as tube bundle heat exchangers, the steam to be heated flowing around the tubes and being heated by the steam condensing in the tubes.
  • heating is carried out with live steam, while in the case of multi-stage superheating, tap and live steam are used.
  • Reheaters of the horizontal design usually work with 1-2% purge steam, based on the total heating steam consumption.
  • the one to avoid operational cases required safety devices, which can lead to the destruction of the tube bundle, for example, by gushing and / or plug flow, are extensive and complex.
  • the flushing steam requirement is lower, but their space requirement is considerably larger.
  • thermodynamic efficiency is therefore much better than in systems without reheaters.
  • the object of the present invention is to be seen in creating a saturated steam turbine plant in which a better efficiency than with two-stage water separation can be achieved without an intermediate superheater, and in which the intermediate superheater can be arranged in any installation position without any particular effort.
  • the advantage of the arrangement according to the invention can be seen in particular in the shorter line routing between the high-pressure and low-pressure part, and in the small space requirement of the reheater bundles, since their installation and installation downstream of the high-speed water separator mean that the installation position is arbitrary, i.e. according to the space available, and the flow cross-section of the reheater is approximately the same compared to the connecting line. Furthermore, the total pressure loss is reduced by this arrangement, and the acceleration and deceleration phases in the working steam are eliminated. In conventional superheating, about 10%, but in the inventive arrangement of the reheater, only about 5% live steam is required.
  • 1 and 2 1 denotes a high-pressure turbine, the exhaust steam of which is fed via connecting lines 2 to low-pressure turbines 3.
  • two low-pressure turbines 3 are provided, the high-pressure turbine l, the two low-pressure turbines 3 and a generator 4 are connected by a common shaft 5.
  • a high-speed water separator 6 and a reheater bundle 7 are arranged downstream of the high-pressure turbine 1 in the underflow and upstream connecting lines 2, which require little space and whose flow cross section differs only insignificantly from the cross section of the connecting lines.
  • a flap valve 8 is provided between each reheater bundle 7 and the respective low-pressure turbine 3, but it is easily possible to omit the flap valves 8 without causing damage to the low-pressure turbines 3 due to excessive speeds.
  • FIG 3 shows a possible arrangement of the reheater bundle 7 with a trap flap 8 in the connecting line 2 between the low-pressure turbine 3 and the entry of the working steam from the high-speed water separator (not shown).
  • the working steam flows through the superheater tubes 9 arranged in the intermediate superheater 7 in the direction of the arrow in a cross flow the condensate flows off.
  • the intermediate superheaters for example L-shaped or U-shaped, and also spiral-shaped to compensate for the differential expansions that occur.
  • the reheater can be easily adapted to the local conditions.
  • Heater 7 in the connecting lines 2 Due to the arrangement of the intermediate according to the invention Heater 7 in the connecting lines 2, a multi-stage superheating is possible without additional space requirement, and since the reheater 7 forms part of the connecting lines 2, any installation position is possible.
