Definitions
- the invention relates to a method for generating steam with defined steam parameters according to the preamble of independent claim 1.
- Steam is often used in processes and in the heat supply, in the following the term industrial processes is used in general.
- a typical area of application is the provision of heat, for example for cooking, evaporation or distillation processes.
- drying processes or the provision of heat for endothermic reactions in the chemical industry can be realized with steam.
- Steam which is used in industrial processes is often referred to as process steam.
- the object of the present invention is to avoid the disadvantages of the prior art when providing steam with defined steam parameters and to demonstrate a more effective process for providing the steam.
- the object is solved by the features of independent claim 1.
- One embodiment of the invention provides that the hydrogen and oxygen used for combustion is generated using regenerative energy. As a result, the process steam can be generated completely emission-free.
- a further embodiment of the invention provides that at least part of the live steam is removed before it enters the steam turbine and fed directly to an industrial process.
- the steam parameters of the live steam which is produced during the internal combustion of hydrogen with oxygen, can be influenced in such a way that at least part of the live steam can be fed directly to the industrial process. If additional steam with lower steam parameters is required, this can be provided by expanding another part of the live steam in a steam turbine.
- a further embodiment of the invention provides that the mechanical energy generated by the steam turbine is used to drive machines and/or to generate electrical energy with the aid of a generator. Due to the double use of the steam, which is also referred to as combined heat and power generation, particularly high overall efficiencies can be achieved, which increase the economic speed of the method according to the invention.
- FIG. 1 shows a plant which is suitable for carrying out the method according to the invention.
- the figure only shows the essential ones to explain the Components necessary for the process and do not represent a true-to-scale representation.
- the system for carrying out the method according to the invention essentially comprises a steam generator 1 and a steam turbine 2 downstream of the steam generator.
- the steam is generated by internal combustion and not, as is otherwise customary, by the pure supply of heat (partly from external combustion), as is the case, for example, when using a conventional boiler.
- the internal combustion takes place in a steam generator 1 referred to as Clean Steam Generator, CSG.
- CSG Clean Steam Generator
- the CSG 1 is produced by pressurized, internal combustion of hydrogen H 2 with oxygen 0 2 and the addition of water H 2 0 2 (irrespective of the state of aggregation ) characterized, whereby live steam SL is produced with defined steam parameters (pressure, temperature%) and in a defined quantity and purity.
- the live steam S L is then fed to the steam turbine 2 downstream of the CSG.
- the live steam is expanded to lower steam parameters along an expansion path, which extends from a steam turbine inlet 4 to a steam turbine outlet 5 .
- the steam can be removed along the expansion section by one or more intermediate steam extractions and fed to the respective industrial process as process steam S P2 .
- the remaining part of the steam is completely expanded along the expansion section and leaves the steam turbine at the steam turbine outlet 5 as exhaust steam S.
- the exhaust steam can then be fed to a condenser or to another industrial process as process steam S P 3 .
- the steam turbine 1 is designed as a (extraction) condensation turbine or as an (extraction) back-pressure turbine.
- part or all of the live steam can be derived before the steam turbine and fed directly to an industrial process as process steam S Pi .
- the distribution of the water vapor S Pi - S P 3 to the different union industrial processes can vary both in terms of time and the respective amount of steam.
- the steam turbine drives a generator 3 for generating electrical energy; alternatively, the steam turbine can also drive a working machine (compressor, pump,).
- the steam turbine can be designed in one or more stages and also consist of one or more housings.
- the live steam can be divided between several steam turbines, expanded and fed to the various industrial processes.
- the various steam turbines and housings can be operated at the same or different speeds and do not necessarily have to be mechanically coupled to one another via a shaft (several generators) and do not necessarily have to serve the same purpose (e.g. high-pressure turbine as a mechanical drive for a prime mover, low-pressure turbine as a generator drive). .)
- the hydrogen and oxygen used for combustion can preferably be generated using regenerative energy and then stored for further use in the CSG. Due to the regenerative production of the hydrogen and the oxygen, the method according to the invention for the production of process steam can be CCh-free.
- the method according to the invention for generating steam offers significant advantages over the conventional methods both in terms of fuel utilization and operational flexibility (the CSG can run higher load gradients than a conventional boiler).
