Definitions
- the invention relates to a once-through steam generator in which an evaporator pass-through heating surface is arranged in a gas train through which an approximately vertical heating gas direction can flow, and which comprises a number of steam generator pipes connected in parallel to flow through a 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 waste heat steam generator connected downstream of the gas turbine, in which a number of heating surfaces for water preheating, steam generation and steam superheating are usually arranged.
- the heating surfaces are connected to the water-steam cycle of the steam turbine.
- the water-steam cycle usually comprises several, e.g. B. three, pressure levels, each pressure level can have an evaporator heating surface.
- 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 fresh steam pressures far above the critical pressure of water (P Kr i «221 bar) - where there are only slight differences in density between liquid-like and steam-like medium - are possible.
- a high live steam pressure favors high thermal efficiency and thus low C0 2 emissions from a fossil-fired power plant.
- a continuous steam generator has a simple design compared to a circulation steam generator and can therefore be produced with particularly little effort.
- the use of a steam generator designed according to the continuous flow principle as waste heat steam generator of a gas and steam turbine system is therefore particularly favorable in order to achieve a high overall efficiency of the gas and steam turbine system with a simple construction.
- Such a heat recovery steam generator can be carried out in a technically particularly simple manner by the heating gas supplied to the steam generator from the gas turbine flowing through the gas train in a vertical direction, in particular from bottom to top.
- two possible concepts come into consideration for the connection of the steam generator tubes forming the evaporator flow heating surface on the flow medium and hot gas side: Either the steam generator tubes laid within the gas flue are flowed through in the so-called cross or counterflow by the flow medium, that is, the flow medium is flowed through each heating surface tube in successive passes through the gas channel across the gas flow, hence the designation cross-flow switching.
- the horizontal pipe sections leading from one side of the gas channel to the other side are connected to one another via deflection pieces in such a way that they are successively flowed through in the vertical direction against the flow direction of the gas, hence the designation countercurrent circuit.
- This circuit is therefore referred to below only as a countercurrent circuit. It is generally known that an evaporator heating surface in countercurrent circuit is problematic with regard to the stability of the flow. In particular, a uniform distribution of the flow over all parallel tubes of the evaporator heating surface requires technical effort.
- An alternative to the countercurrent circuit is the so-called direct current circuit, in which the steam generator tubes are flowed through in cross / direct current.
- the horizontally guided pipe sections are connected to one another via deflection pieces, as in the cross-flow circuit described above, only that they are now flowed through successively in the vertical direction in the direction of flow of the gas, hence the name DC circuit.
- This circuit is therefore referred to below only as a DC circuit.
- a DC circuit requires the use of relatively large heating surfaces, the manufacture and assembly of which are associated with considerable effort.
- a steam generator is known from EP 0 425 717 A, which has the advantages mentioned of a once-through steam generator. Its evaporator flow heating surface is designed as a combination of countercurrent and direct current switching, in that a number of pipe sections is switched in the counterflow direction, while a number of further pipe sections are connected in the direct current direction. This type of connection enables a higher degree of flow stability to be achieved than with a purely counterflow switch. In addition, when using a pure DC circuit necessary high technical and apperative effort can be reduced.
- the invention is therefore based on the object of specifying a once-through steam generator of the type mentioned above which, even when subjected to comparatively large mass flow densities of the flow medium, even with different heating of the steam generator tubes, has a particularly high stability, in particular with respect to temperature imbalances.
- the evaporator once-through heating surface comprises a heating surface segment through which the flow medium can flow in countercurrent to the gas flue, the outlet of which on the flow medium side is positioned in the direction of the hot gas, such that the saturated steam temperature which occurs in the evaporator once-through heating surface during operation is less than a predetermined maximum deviation the heating gas temperature prevailing at the position of the outlet of the heating surface segment differs in operation.
- the invention is based on the consideration that when feeding the evaporator continuous heating surface with comparative large mass flow densities, a locally different heating of individual pipes could influence the flow conditions in such a way that more heated pipes flow through less and less heated pipes through more flow medium.
- multi-heated pipes would be cooled less well than lower-heated pipes, so that the temperature differences that occurred would be amplified automatically.
- the system should be suitably designed for a general and global limitation of possible temperature differences.
- the knowledge that the flow medium at the outlet from the evaporator pass-through heating surface must have at least the saturated steam temperature essentially given by the pressure in the steam generator tube can be used for this purpose.
- the flow medium can have a maximum of the temperature that the heating gas has at the point of exit of the flow medium from the evaporator continuous heating surface.
- the maximum possible temperature imbalances can thus be suitably limited by appropriately coordinating these two limit temperatures which limit the possible temperature interval at all.
- the outlet in the heating gas direction can be freely positioned so that an additional design parameter is available.
- a particularly suitable means of coordinating the two limit temperatures with one another is the targeted positioning of the outlet of the evaporator passage heating surface in the flow direction of the heating gas.
- the positioning of the outlet of the evaporator continuous heating surface in relation to the temperature profile of the heating gas in the gas flue is selected such that a maximum deviation of approximately 50 ° C. is maintained, so that with regard to available materials and further design parameters a particularly high level of operational security is guaranteed.
- Flow oscillations occur when the area within the steam generator tube in which evaporation takes place shifts significantly within the tube when a steam generator tube is heated more.
- the shifting of the evaporation area within a steam generator tube undesirably influences the pressure loss of the flow within the evaporator flow heating surface. Therefore, in the case of a steam generator that is so sensitive to a different heating of the steam generator tubes, throttles could be provided at the inlet of all steam generator tubes, which allow the pressure loss of the flow within the evaporator passage heating surface to be controlled over a relatively large area.
- the evaporator continuous heating surface advantageously comprises a further heating surface segment upstream of the heating surface segment on the flow medium side, which heating surface is expediently arranged in front of the heating surface segment.
- the further heating surface segment upstream of the heating surface segment on the flow medium side is advantageously likewise designed in the manner of a countercurrent section or alternatively connected in direct current to the heating gas direction.
- the steam generator is expediently used as a waste heat steam generator in a gas and steam turbine plant.
- the steam generator is advantageously connected downstream of a gas turbine on the hot gas side. In this circuit, additional firing for increasing the heating gas temperature can be expediently arranged behind the gas turbine.
- the stated object is achieved in that the flow medium, viewed in the direction of the heating gas, is discharged from the evaporator flow heating surface at a position at which the heating gas temperature prevailing in operation is less than a predetermined maximum deviation from the saturated steam which arises in operation due to the pressure loss in the evaporator flow heating surface temperature differs.
- the flow medium is guided in counterflow to the hot gas direction before it emerges from the evaporator continuous heating surface.
- the flow medium flows through the flow medium against the direction of the heating gas, ie from top to bottom.
- the advantages achieved by the invention consist in particular in that the now provided, adapted to the temperature profile of the heating gas in the gas flue positioning of the outlet on the flow medium side of the evaporator pass-through heating surface, the overall temperature interval achievable in the evaporation of the flow medium between saturated steam temperature of the flow medium and heating gas temperature at the Outlet point is comparatively narrowly limited, so that only small outlet-side temperature differences are possible regardless of the flow conditions. Thereby sufficient adjustment of the temperatures of the flow medium can be ensured in every operating condition.
- the continuous evaporator heating surface is the continuous evaporator heating surface
- Flow through the evaporator is more stable in terms of flow than a pure counterflow circuit. This ensures a particularly high flow stability and a particularly high level of operational safety for the steam generator. In addition, however, it is also ensured that the possible outlet temperatures are limited in terms of their absolute level, so that the permissible limit temperatures specified by the material properties remain safely below.
- FIG. 1 shows a simplified representation of a section in longitudinal section of a continuous steam generator
- FIG. 2 shows the evaporation section of the once-through steam generator according to FIG. 1 in an alternative embodiment.
- the continuous steam generator 1 according to FIG. 1 is connected in the manner of a heat recovery steam generator on the exhaust gas side of a gas turbine (not shown in more detail).
- the continuous steam generator 1 has a peripheral wall 2, which forms a gas duct 6 for the exhaust gas from the gas turbine, through which the heating gas direction y can be flowed in an approximately vertical direction indicated by the arrows 4.
- a number of heating surfaces designed according to the continuous flow principle, in particular an evaporator continuous heating surface 8, are arranged in the gas flue 6. In the exemplary embodiment according to FIG. 1, only the evaporator continuous heating surface 8 shown, but a larger number of continuous heating surfaces can also be provided.
- the evaporator system formed from the evaporator pass-through heating surface 8 can be acted upon with flow medium W, which evaporates once through the evaporator pass-through heating surface 8 and is discharged as steam D after exiting the evaporator pass-through heating surface 8 and is usually supplied with superheater heating surfaces for further overheating. That formed from the evaporator heating surface 8
- Evaporator system is connected in the water-steam cycle of a steam turbine, not shown.
- a number of further heating surfaces are connected in the water-steam circuit of the steam turbine.
- the heating surfaces can be, for example, superheaters, medium pressure evaporators, low pressure evaporators and / or preheaters.
- the evaporator continuous heating surface 8 of the continuous steam generator 1 according to FIG. 1 comprises a tube bundle type
- a plurality of steam generator tubes 12 which are connected in parallel to flow through the flow medium W
- a plurality of steam generator tubes 12 are arranged next to one another as seen in the heating gas direction y. Only one of the steam generator tubes 12 arranged next to one another in this way is visible.
- the steam generator tubes 12 each comprise a number of pipe sections through which there is horizontal flow, two of which are each connected by a pipe section through which there is a vertical flow. In other words: the steam generator tubes are each meandering inside the gas cable 6.
- the steam generator tubes 12, which are arranged next to one another in this way are each followed by a common inlet header 14 at their inlet 13 into the evaporator once-through heating surface 8 and a common outlet header 18 at their outlet 16 from the evaporator once-through heating surface 8.
- the continuous steam generator 1 is designed for a particularly high level of operational safety and for the consequent suppression of significant temperature differences at the outlet 16 between adjacent steam generator tubes 12, also referred to as temperature unbalance, even when fed with comparatively high mass flow densities.
- the evaporator flow-through heating surface 8 comprises, in its rear region as seen on the flow medium side, a heating surface segment 20 which is connected in countercurrent to the heating gas direction y.
- the evaporator continuous heating surface 8 comprises a further heating surface segment 22 connected upstream of this on the flow medium side.
- the switching of the outlet 16 in the heating gas direction y can be selected by means of this circuit.
- This positioning is selected in the continuous steam generator 1 in such a way that the saturated steam temperature of the flow medium W which is set in the evaporator continuous heating surface 8 as a function of pressure is less than a predetermined maximum deviation of approximately 50 ° C. from that in the operating case at the position or at the height of the outlet 16 Heating surface segment 20 prevailing heating gas temperature. Since the temperature of the flow medium W at the outlet 16 must always be at least equal to the saturated steam temperature, but on the other hand cannot be higher than the heating gas temperature prevailing at this point, the possible temperature differences between differently heated pipes are without further countermeasures to the predetermined maximum deviation of about 50 ° C limited.
- the first heating surface segment 20 is connected to the second heating surface segment 22 by a connecting piece 24.
- the evaporator pass-through heating surface 8 comprises the further heating surface segment 22, the connecting piece 24 connected downstream of this on the flow medium side, and the flow piece flowing to the connecting piece 24. Heating surface segment 20 connected on the medium side.
- the further heating surface segment 22 is likewise connected in counterflow to the heating gas direction 4.
- both the alternative circuit shown in FIG. 1 and the one shown in FIG. 2 of the evaporator continuous heating surface 8 have a particularly high flow stability.
- the occurrence of flow oscillations is reliably prevented. These occur when a different heating of individual steam generator tubes 12 shifts the evaporation area within the relevant steam generator tube 12 strongly along the flow direction of the flow medium W.
- flow oscillations can be avoided by artificially increasing the pressure loss in the flow medium W when flowing through the evaporator pass-through heating surface 8 by throttling at the entry of the tubes.
- the problem of flow oscillations does not occur. It has been shown that the evaporation area moves comparatively little within the respective steam generator tube 12 in the event of a different heating. To stabilize the flow, therefore, only a slight artificial increase in pressure loss is required.
