Definitions

  • the invention relates to a continuous steam generator with a surrounding a gas train surrounding wall formed in a lower region of gas-tight welded together evaporator tubes and in an upper region of gas-tight welded together Uberhitzerrohren, wherein the superheater tubes are downstream of the evaporator tubes flow side through a Wasserabscheidesystem.
  • a continuous steam generator In a continuous steam generator, the heating of a number of evaporator tubes, which together form the gas-tight enclosure wall of a combustion chamber, leads to 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 pressure limitation, so that it is possible for fresh 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.
  • such a continuous steam generator is usually operated with a minimum flow of flow medium in the evaporator tubes in order to ensure reliable cooling of the evaporator tubes.
  • the pure mass flow through the evaporator usually no longer suffices for cooling the evaporator tubes, so that an additional throughput of flow medium is superimposed on the passage of flow medium through the evaporator in circulation.
  • the operationally provided minimum flow of flow medium in the evaporator tubes is thus not fully evaporated during startup or in low load operation in the evaporator tubes, so that in such a mode at the end of the evaporator tubes still unvaporized flow medium, in particular a water-steam mixture is present.
  • continuous steam generators are usually designed so that even when starting and in low load operation, a water ingress into the superheater tubes is reliably avoided.
  • the evaporator tubes are usually connected to the superheater tubes connected downstream via a Wasserabscheidesystem.
  • the water separator causes a separation of the emerging during the start or in low load operation of the evaporator tubes water-steam mixture in water and in steam.
  • the steam is supplied to the water separator downstream superheater tubes, whereas the separated water can be fed back to the evaporator tubes, for example via a circulating pump or discharged through a decompressor.
  • a continuous steam generator of the above type is known for example from DE 197 02 133 A1.
  • the evaporator tubes forming the lower part of the surrounding wall of the gas flue usually open into one or more outlet collectors, from which the flow medium is guided into a downstream water-steam separator. There is a separation of the Flow medium in water and in steam, wherein the steam is transferred into a distribution system upstream of the superheater tubes, where a division of the steam mass flow takes place on the individual Uberhitzerrohre parallel flow medium side.
  • 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 of specifying a continuous steam generator of the type mentioned above, which has a particularly high operational flexibility with relatively low manufacturing and assembly costs even when starting and in low load operation.
  • the Wasserabscheidesystem a plurality of Wasserabscheiderettin each of which is followed by less than ten, preferably a single, evaporator tube and / or less than ten, preferably a single, superheater tube downstream of 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 effluent from the evaporator tubes flow
  • the subsequent separation of water in a central Wasserabscheide drove 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 the evaporator and / or superheater tubes are assigned individually or in small groups combined Wasserabscheideretti.
  • the surrounding wall of the throttle cable can be bored perpendicular or spiral wound.
  • the number of superheater tubes can be chosen such that each overbitzer tube can be individually connected downstream of an evaporator tube via an interposed water separator element in the sense of a one-to-one allocation.
  • a required displacement of the evaporation end point of the evaporator tube in the respective downstream superheater tube allows.
  • the number of evaporator tubes can be selected smaller than the number of - preferably vertically arranged - superheater tubes.
  • each evaporator tube via an associated Wasserabscheiderelement a plurality of superheater tubes, for example, three superheater tubes to be connected downstream.
  • the water separator elements which are assigned individually or in smaller groups to the evaporator and / or superheater pipes made it possible to ensure decentralized separation of water in the individual pipe so that the evaporation end point can be shifted from the evaporator to the downstream superheater pipes in regular operating states.
  • Such a configuration makes it possible in particular for the spatial transition region from the evaporator tube to the superheater tubes in the surrounding wall of the continuous steam generator to be displaced comparatively far downwards, ie toward the burner arranged in the area surrounding the evaporator tubes in the surrounding wall.
  • the portion of the surrounding wall of the continuous-flow steam generator operated in start-up or low-load operation with a superposed circulation can be kept comparatively small and, in particular, limited to the area of the actual requirement, ie the area of comparatively high heat flow densities in the immediate vicinity of the burners.
  • the total required superimposed circulation can be provided with a comparatively low effort.
  • the Wasserabscheiderieri are advantageously positioned at a height of up to 20 m above the uppermost burner in the enclosure wall.

  • the knowledge is preferably used that the water content of the flow medium preferably continues to flow straight ahead in its flow direction due to its higher inertia compared to the vapor component, while the vapor component is comparatively better able to follow an imposed deflection.
  • this is implemented in a particularly advantageous embodiment in the manner of a T-piece.
  • the respective Wasserabscheiderelement preferably comprises a connected to the upstream evaporator tube Einströmrohr laminate, which is seen in its longitudinal direction merges into a Wasserableitrohr sensible, wherein in the transition region branches off a number of connected to the downstream superheater tube Abströmrohr structurien.
  • the water content of the flow medium flowing into the inflow pipe section is transported further at the branching point substantially without deflection in the longitudinal direction and thus passes into the water drainage pipe section.
  • a deflection is easier for the vapor content due to its relatively lower inertia, so that the vapor content in the branching or the AbströmrohrFigs.
  • the Einströmrohr choir is designed to be substantially rectilinear, wherein it may be arranged with its longitudinal direction substantially horizontally or in a predetermined tilt or tilt angle.
  • an inclination in the flow direction downwards is preferably provided.
  • an inflow of the inflow pipe piece may be provided via a pipe bend coming from above, so that in this case the flow medium is pressed towards the outside of the curvature due to the centrifugal force.
  • the water component of the flow medium preferably flows along the outer region of the bend. at This configuration is thus preferably aligned for the discharge of the vapor portion provided Abströmrohr Kunststoff to the inside of the curvature.

  • the water separator elements downstream water components such as outlet header or water tank are first completely filled with water, so that forms a backwater with further inflowing water in the corresponding line pieces.
  • this backwater has reached the Wasserabscheideremia, at least a partial flow of new inflowing water is passed along with the entrained in the flow medium vapor to the subsequent superheater tubes.
  • a control valve which can be actuated via an associated control device is connected in a drain line connected to the water collecting tank. The control device is advantageously acted upon by an input value characteristic of the enthalpy of the flow medium at the flue gas end of the boundary wall formed by the superheater heating surfaces.
  • the mass flow flowing out of the water collecting container can be adjusted in the operating mode of the bypassed separating system by targeted activation of the valve connected in the outflow line of the water collecting container. Since this is replaced by a corresponding mass flow of water from the Wasserabscheiderettin, thus the mass flow is adjustable, consisting of the Water separator enters the collection system.
  • that partial flow is adjustable, which is passed together with the steam in the superheater tubes, so that a predetermined enthalpy can be maintained via a corresponding setting of this partial flow, for example, at the end of the combustion chamber walls subsequent heating surfaces.
  • the water partial flow passed on together with the steam to the superheater pipes can also be influenced by a corresponding control of the superimposed circulation circuit.
  • a circulation pump associated with the evaporator tubes can be actuated in a further advantageous alternative embodiment via the control device assigned to the water separation system.
  • the advantages achieved by the invention are in particular that by the integration of the water separation in the pipe system of the continuous steam generator, the water separation can be done without prior collection of effluent from the evaporator tubes flow medium and subsequent distribution of the passed to the superheater tubes flow medium to the superheater tubes. This can be costly collection and distribution systems can be saved.
