Definitions

  • the invention relates to a steam generator in which in a Walkergaskanal formed from a number of evaporator tubes evaporator fürlaufterrorism behavior and one of a number of the evaporator tubes flow medium side downstream superheater tubes formed Matterhitzerterrorism phenomenon are arranged.
  • a continuous steam generator In a continuous steam generator, the heating of a number of evaporator tubes leads to a complete evaporation of the flow medium in the evaporator tubes in one pass.
  • the flow medium - usually water - is supplied to the evaporator tubes downstream superheater tubes after its evaporation and overheated there.
  • the position of the evaporation end point, ie the boundary region between unvaporized and vaporized flow medium, is variable and mode-dependent.
  • the evaporation end point is, for example, in an end region of the evaporator tubes, so that the overheating of the evaporated flow medium already begins in the evaporator tubes.
  • 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.
  • the hot exhaust gas from the gas turbine is usually first passed to the uncooled tubes of the superheater section of the continuous steam generator, which usually must be made of high-quality temperature-resistant materials for this reason.
  • the feeding of the evaporator section may be provided with a minimum flow of flow medium to ensure safe cooling of the steam generator tubes.
  • Just at low loads of, for example, less than 40% of the design load of the corresponding steam power flow pass through the steam generator tubes usually no longer sufficient for their cooling, so that this passage of flow medium through the evaporator, an additional flow rate of fluid is superimposed. In this case, usually a separation of water from the flow medium is necessary before it enters the superheater section of the continuous steam generator.
  • the continuous heating surface can be formed in its entirety by a arranged in a Schugaskanal, formed from a number of evaporator tubes evaporator für Aviation Mixing Technology (Gaussian), and by a flow medium side downstream, formed from a number of superheater tubes Kochhitzerterrorism simulation, wherein the flow medium side between the evaporator fürlaufterrorism configuration and Kochhitzerterrorism simulation a Wasserabscheidesystem is connected.
  • the evaporator tubes forming the evaporator section typically open into one or more outlet collectors, from which the flow medium is guided into a downstream water-steam separator. There, a separation of the flow medium in water and in steam, wherein the steam is transferred into a superheater tubes upstream distribution system, where a division of the steam mass flow is carried out on the individual, on the flow medium side parallel superheater tubes.
  • the vaporization end point of the continuous steam generator is determined by the interposition of the Wasserabscheidesystems in start-up and low load operation and not - as in full load operation - variable.
  • the operational flexibility is significantly limited in such a construction of the continuous steam generator in low load operation.
  • the separation systems must generally be designed, in particular with regard to the choice of material, for the steam in the separator to be clearly overheated in the pure continuous operation. The required material selection also leads to a significant restriction of operational flexibility.
  • the said construction also requires that the water discharge occurring during the startup of the continuous steam generator in the first start-up phase must be completely absorbed in the separation system and be able to be discharged via the downstream separation tank and the discharge valves into the expander.
  • the resulting comparatively large dimensioning of separating bottle and drain valves leads to a considerable manufacturing and assembly costs.
  • the invention is therefore based on the object to provide a steam generator of the type mentioned above, which is kept at comparatively low manufacturing and assembly costs also has a particularly high operational flexibility when starting and in low load operation.
  • This object is achieved according to the invention by integrating in each case one water separation element into a number of one or more evaporator tubes, each with one or more superheater tubes connecting the flow medium side.
  • the invention is based on the consideration that the continuous steam generator should be designed to ensure a particularly high operational flexibility even in start-up or low-load operation for a variable evaporation endpoint.
  • the usual construction-related fixation of the evaporation end point in the water separation system should be avoided.
  • this fixation is essentially due to the collection of the flowing out of the evaporator tubes flow medium
  • the subsequent separation of water in a central Wasserabscheide responded and the subsequent distribution of the steam on the superheater tubes
  • a decentralization of Wasserabscheidefunktion should be made.
  • the water separation should in particular be designed such that after the water separation no too complex distribution of the flow medium is provided, since this is not practical for a water-steam mixture. This can be achieved by deviating from the conventionally provided central water-steam separation, the water separation system is designed decentralized, the separation function is integrated into the flow medium-side connection of the evaporator tubes with the downstream superheater tubes anyway necessary pieces of pipe.
  • the continuous steam generator can be designed in so-called upright construction or in so-called horizontal construction.

  • the start-up times of the boiler as a whole or the load change speeds are not further limited by the thin-walled design of Wasserabscheideetic, so that even in systems for high steam conditions comparatively short reaction times can be achieved under load changes.
  • such tees are particularly inexpensive to produce.
  • an intermediate over-feeding of the separation elements during start-up or during low-load operation is permissible, so that part of the evaporator water to be ejected can be collected in the superheater tubes connected downstream of the evaporator tubes.
  • the design of the water collection systems such as the separation bottles or drain valves for correspondingly lower flow rates and thus cost-effective.
  • the displacement of the evaporation end point into the superheater tubes makes it possible to limit a possibly required water injection and the associated losses.
  • the steam generator 1 according to FIG. 1 is designed as a continuous steam generator and is connected downstream of the exhaust gas as part of a gas and steam turbine plant in the manner of a heat recovery steam generator of a gas turbine (not shown).
  • the steam generator 1 has a Um Publishedswand 2, which forms a Schugaskanal 4 for the exhaust gas from the gas turbine.
