- the Heating surfaces are in the water-steam cycle of the steam turbine connected.
- the water-steam cycle typically includes 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 Kri ⁇ 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 CO 2 emissions from a fossil-fired power plant.
- a continuous steam generator has a simple construction in comparison 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.
- a steam generator is known from EP 0 944 801 B1 is suitable for a layout in horizontal construction and also has the mentioned advantages of a once-through steam generator.
- This is the well-known steam generator in terms of its Evaporator flow heating surface designed such that a compared to another steam generator tube of the same Evaporator continuous heating surface multi-heated steam generator tube a higher compared to the other steam generator tube Has flow rate of the flow medium.
- the continuous evaporator heating surface of the known steam generator thus shows in the type of flow characteristic of a natural circulation evaporator heating surface (Natural circulation characteristic) when occurring different heating of individual steam generator tubes a self-stabilizing behavior that without the requirement external influence to align the exit side Temperatures also at differently heated, Steam generator tubes connected in parallel on the flow medium side leads.
- the well-known steam generator is in constructive aspects, especially with regard to the water and / or distribution of the flow medium on the steam side, comparatively complex.
- the invention is therefore based on the object of a steam generator of the type mentioned above, with particular can be produced with little effort, and even with different a particularly high mechanical load Has stability.
- one or each of the steam generator tubes is approximately vertical arranged, from the flow medium in the upward direction
- Flowable riser pipe section one on the flow medium side downstream, approximately vertically arranged and Down pipe section through which the flow medium can flow and a the downpipe piece on the flow medium side downstream, flowable in the upward direction
- riser pipe is approximately vertical arranged, from the flow medium in the upward direction
- the invention is based on the consideration that in one with particularly low assembly and manufacturing costs producible steam generator for a particularly stable and against differences in thermal stress particularly insensitive operating behavior that with the known Steam generator applied design principle of a natural circulation characteristic for a continuous evaporator heating surface should be expanded and further improved.
- the continuous evaporator heating surface should be there for an application with comparatively low mass flow density with comparatively lower friction pressure loss.

This is ensures that in the entire load range from the respective first riser pipe flow medium with comparatively emits a high proportion of steam.
- This leads to the following Introduction into the downstream downpipe piece that in Downpipe piece an unfavorable for the flow stability Rise of vapor bubbles against the flow direction of the Fluid is avoided consistently.
- the first riser pipe pieces fulfills the function of a pre-evaporator.
- a particularly simple construction of the evaporator continuous heating surface on the one hand and a particularly low mechanical Load on the evaporator continuous heating surface even with different thermal exposure on the other hand is achievable by being more advantageous in another or alternative Embodiment of the riser pipe section of one or each steam generator pipe with the downpipe piece assigned to it and the Downpipe piece of one or each steam generator tube with the further riser pipe section assigned to it on the flow medium side is connected via an overflow piece.
- Such an arrangement is particularly for expansion compensation suitable for thermal alternating loads; that this Riser pipe section and the down pipe section or that Downpipe piece and the further riser pipe connecting

- the steam generator is advantageously one on the hot gas side Downstream gas turbine.
- This circuit can be used expediently Additional firing to increase the gas turbine the heating gas temperature may be arranged.
- the advantages achieved with the invention are in particular in that the three-stage design of the Steam generator tubes with a flow through in the upward direction Riser pipe section, a flow through in the downward direction Downpipe piece and this one on the flow medium side downstream, flowable in the upward direction Riser pipe the complete implementation of the evaporation, so partial preheating, evaporation and a partial Overheating, in just one step and without intermediate switching of components for collecting or distributing a particularly simple construction is achievable.
- Heated evaporator systems flow downwards usually to flow instabilities, especially in the Use in forced flow evaporators are not tolerable.
- a flow with a comparatively low mass flow density is due to the comparatively low loss of friction pressure but in a reliable manner a natural circulation characteristic of the steam generator tube achievable at a More heating of a steam generator pipe compared to one another steam generator tube to a comparatively higher one Throughput of the flow medium in the multi-heated steam generator tube leads.
- This natural circulation characteristic ensures even when using the downward flow segments sufficiently stable and reliable flow through the steam generator tubes.
- Such a characteristic is also particularly low Constructional and assembly effort can be achieved by using the downpipe piece the respective riser pipe section assigned to him the further riser pipe that is assigned to it Downpipe piece directly and without interposing one complex collector or distribution system downstream is.
- the steam generator thus has a particularly stable Flow behavior a comparatively low system complexity on.
- Embodiments of the invention are based on a drawing explained in more detail.
