Definitions

  • the invention relates to a method for operating a steam generator with an evaporator through-flow surface arranged in a heating gas duct which can be flowed through in an approximately horizontal heating gas direction, comprising a number of steam generator tubes connected in parallel to flow through a flow medium, each of which has an approximately vertical flow through the flow medium in the downstream direction Downcomer pipe and a this downstream of the flow medium side, arranged approximately vertically and by the flow medium in the upward directionteurströmbares riser pipe, wherein the evaporator fürlaufterrorism behavior is designed such that a more compared to another steam generator the same evaporator fürlaufsammlungsynthesis configuration more heated steam generator tube compared to the other steam generator tube higher throughput having the flow medium.
  • the heat contained in the relaxed working fluid or heating gas from the gas turbine is used to generate steam for the steam turbine.
  • the heat transfer takes place in a heat recovery steam generator connected downstream of the gas turbine, in which a number of heating surfaces for water preheating, steam generation and steam superheating is usually arranged.
  • the heating surfaces are connected in the water-steam cycle of the steam turbine.
  • the water-steam cycle usually comprises several, e.g. three, pressure stages, each pressure stage may have a Verdampferloom phenomenon.
  • a continuous steam generator In contrast to a natural or forced circulation steam generator, a continuous steam generator is not subject to any pressure limitation, so that it is possible for live steam pressures far above the critical pressure of water (P Kri ⁇ 221 bar) - where no differentiation of the phases water and steam and thus no phase separation is possible. can be designed.
  • a high live steam pressure promotes a high thermal efficiency and thus low CO 2 emissions of a fossil-fired power plant.
  • a continuous steam generator in comparison to a circulating steam generator a simple construction and is thus produced with very little effort.
  • the use of a designed according to the flow principle steam generator as heat recovery steam generator of a gas and steam turbine plant is therefore particularly favorable to achieve a high overall efficiency of the gas and steam turbine plant with a simple design.
  • a steam generator which is suitable for a design in horizontal design and also has the advantages of a continuous steam generator mentioned.
  • the evaporator heating surface of the known steam generator is connected as Norlaufterrorism phenomenon and designed such that a more heated compared to another steam generator tube fürlaufterrorism related steam generator tube has a higher compared to the other steam generator tube throughput of the flow medium.
  • continuous heating surface is generally to be understood a heating surface, which is designed for a flow according to the flow principle. The flow medium supplied to the evaporator heating surface interconnected as a continuous heating surface is thus completely evaporated in a single pass through this continuous heating surface or through a heating surface system comprising a plurality of continuous heating surfaces connected in series.
  • the evaporator fürlaufterrorism the steam generator in the Art
  • a U-shaped construction of a number of parallel to the flow of the flow medium steam generator tubes may be formed, each having an approximately vertically arranged, from the flow medium in the downward flow-through downpipe piece and this downstream of the flow medium side, approximately vertically arranged and flow medium through-flow in the upward direction riser piece.
  • the flow through the fürlaufterrorism decisions favors - flow-promoting - pressure contribution on the geodetic pressure of the water column located in the downpipe of each steam generator tube water column available.
  • the invention is therefore based on the object to provide a method for operating a steam generator of the type mentioned above, with a relatively high degree of flow stability in the operation of the evaporator fürlauf redesign construction can be achieved in a relatively simple manner.
  • this object is achieved in that the flow medium of the evaporator fürlaufments Design is supplied such that it has a flow rate of more than a predetermined minimum speed in the downcomer of the respective steam generator tube.
  • the invention is based on the consideration that a particularly high flow stability and thus a particularly high level of operational safety for the steam generator of the type mentioned above can be achieved by consistently suppressing possible causes for self-adjusting flow instabilities.
  • one of these possible causes may be the occurrence of vapor bubbles in the downcomer of the respective steam generator tube. If, in fact, vapor bubbles should form in the downcomer piece, they could rise in the water column located in the downcomer piece and thus perform a movement counter to the flow direction of the flow medium.
  • the flow direction of the flow medium oppositely directed movement of possibly existing vapor bubbles consistently, by a suitable specification of the operating parameters, a forced entrainment of the vapor bubbles in the actual flow direction be ensured of the flow medium.
  • This can be achieved by feeding the evaporator pass-through heating surface with flow medium in a suitable manner, wherein a sufficiently high flow velocity of the flow medium in the steam generator tubes brings about the desired entrainment effect on the possibly existing or forming vapor bubbles.
  • the flow rate of the flow medium in the downcomer piece of the respective steam generator tube is adjusted such that in the permissible operating range in any case a take-over of possibly existing vapor bubbles is ensured.
  • the flow velocity required for entrainment of the vapor bubbles is advantageously set as the minimum velocity for the flow velocity of the flow medium in the downcomer of the respective steam generator tube.
  • the setting of a sufficiently high flow rate of the flow medium in the downcomer of the respective steam generator tube is possible in a particularly simple manner by the flow medium is supplied to the downcomer of the respective steam generator tube in teilverdampftem state and / or with a certain minimum enthalpy.
  • the flow medium is advantageously partially pre-evaporated prior to its entry into the evaporator fürlaufsammlung construction that it has a vapor content and / or an enthalpy of more than a predetermined minimum steam content or a predetermined minimum enthalpy when entering the evaporator fürlaufterrorism behavior.
  • a desired vapor content and / or a desired enthalpy of the flow medium is adjustable.
  • a suitable choice of the vapor content and / or the enthalpy of the flow medium flowing through the flow heating surface above a predetermined minimum steam content and / or a predetermined minimum enthalpy a sufficient flow velocity of the flow medium can be ensured in the downer piece of the respective steam generator tube fürlauf carving procedure.
  • the flow rate of a water-steam mixture is in fact higher with the same mass flow rate, the greater the vapor content and thus the specific volume of the mixture.
  • the flow rate of the water-steam mixture can be set in particular so high that possibly present in the downpipe section of each steam generator tube existing steam bubbles reliably and can be transferred to the respective downcomer branch piece of riser pipe. Even with the U-shaped design of the steam generator tubes of the evaporator fürlaufsammlung construction thus one of the flow direction of the flow medium opposite movement of the vapor bubbles is safely excluded, so that a particularly high flow stability and thus a particularly high operational safety for the steam generator with such a designed evaporator fürlaufsammlung construction is guaranteed.

In addition to this evaporator system are in the water-steam cycle of the steam turbine, a number of others, in FIG. 1 not shown heating surfaces connected, which are, for example, superheater, Medium-pressure evaporator, low-pressure evaporator and / or can act to preheater.
  • the evaporator fürlaufsammlung configuration 8 of the steam generator 1 comprises in the manner of a tube bundle a plurality of parallel to flow through the flow medium W steam generator tubes 12.

  • a steam generator tube 12 designed in this way the geodetic pressure contribution of the flow medium W in the region of the downcomer piece 20-in contrast to the region of the riser piece 22-produces a flow-promoting and not a flow-inhibiting pressure contribution.
  • the water column located in the downpipe piece 20 of the unvaporized flow medium W "pushes" the flow through the respective steam generator tube 12, instead of impeding it.
