DETAILED DESCRIPTION OF INVENTION

[0028] In the figures, the same designations denote components that are functionally the same.

[0029] FIG. 1 shows a schematic representation of an installation (20) according to the invention.

[0030] In a steam generator (1), water is heated. The water is thereby heated until it is in the form of steam. The high-pressure live steam thereby generated is then fed to a high-pressure part-turbine (2). In the high-pressure part-turbine (2), the energy of the steam is converted into mechanical energy. As this happens, the temperature and pressure of the steam fall. After the high-pressure part-turbine (2), the steam flows by way of a cold reheater line “kZÜ” (3) to a reheater (4). There, the temperature of the steam is increased again. The steam then flows by way of a hot reheater line “hZÜ” (5) into a medium-pressure part-turbine (6). After the medium-pressure part-turbine (6), the steam flows to a low-pressure part-turbine (not shown). The medium-pressure part-turbine (6) shown in FIG. 1 may also represent a combined medium-pressure and low-pressure part-turbine, in which the medium-pressure and low-pressure part-turbines have a common housing.

[0031] After the low-pressure part-turbine, the steam flows by way of a line (7) into a condenser (8), where it condenses again into water. The water thereby produced is passed by means of a pump (9) again by way of a line (10) to the steam generator (1).

[0032] A generator (11) is connected in a torque-transmitting manner to the steam turbine, with the steam turbine being understood as meaning the entirety of the high-pressure part-turbine, medium-pressure part turbine and low-pressure part turbine.

[0033] According to the invention, a booster (12) is arranged in the hot reheater line “hZÜ” (5). The booster (12) is designed in such a way that it can allow hydrogen and oxygen to react with one another in an oxyhydrogen reaction. After the reaction, water is produced in a vaporous phase.

[0034] This additional energy is as it were passed into the medium-pressure part-turbine (6). What is important here is that the mass flow of the steam is not necessarily increased by the booster (12), but rather the energy of the steam. Therefore, steam from the steam generator (1) mixed with steam produced by the booster (12) flows into the medium-pressure part-turbine (6).

[0035] The booster (12) is preheated before operation begins. It has been found that a stable reaction is produced if the booster (12) is preheated.

[0036] This preheating is performed with a device that is not shown.

[0037] In an alternative embodiment, the preheating may be performed with steam. Steam is taken here from the cold reheater line “kZÜ” (3) or from the hot reheater line “hZÜ” (5).

[0038] After the condensation of the steam in the condenser (8), part of the water is fed to an electrolyzer (13). The electrolyzer (13) is designed in such a way that it separates the water into hydrogen and oxygen. This takes place by adding energy.

[0039] The hydrogen and oxygen generated in the electrolyzer (13) are fed to the booster (12), which is symbolically shown at the top right in FIG. 1. This completes a closed cycle.

[0040] In addition to the steam from the hot reheater line “hZÜ” (5), steam is taken from the cold reheater line “kZÜ” (3) and passed to the booster (12) by way of a line (14). This line (14) is connected in terms of flow to the cold reheater line “kZÜ” (3) at a branch (15).

[0041] FIG. 2 shows a known T-S diagram for a water-steam cycle in a steam power plant according to the prior art. The letters shown in FIG. 2 correspond to the positions shown in FIG. 1, but without a booster (12). The following apply: A . . . downstream of the condenser (8), B . . . downstream of the pump (9), C . . . downstream of the steam generator (1), D . . . inlet of the high-pressure part-turbine (2), E . . . outlet of the high-pressure part-turbine (2), F . . . downstream of the reheater (4) upstream of the medium-pressure part-turbine (6), H . . . downstream of the medium-pressure part-turbine (6).

[0042] FIG. 3 shows the T-S diagram of an installation according to the invention. The letters shown in FIG. 3 correspond to the positions shown in FIG. 1. Now with the booster (12). The following applies: G . . . downstream of the booster (12).

[0043] An essential feature of FIG. 3 is that the steam state of the steam changes due to the booster (from F to G). As can be seen from the figure, the mass flow is not increased, but instead the steam parameters, such as the temperature, are increased, as can be seen by the rise from F to G in FIG. 3.

[0044] Although the invention has been more specifically illustrated and described in detail by the exemplary embodiment, the invention is not restricted by the disclosed examples. And other variations can be derived herefrom by a person skilled in the art without departing from the scope of protection of the invention.
