Definitions
- the present invention relates to the field of gas turbine technology. It relates to a gas turbine plant for a working medium in the form of a carbon dioxide / water mixture according to the preamble of claim 1.
- Gas turbine systems are known from the prior art, which work in a circuit with a working medium in the form of a carbon dioxide / water mixture and are characterized in that they combust the combustion of hydrocarbon-containing fuels without releasing carbon dioxide to the Allow atmosphere.
- a gas turbine plant is described, for example, in US-A-5,247,791.
- a comparable gas turbine system 16 is shown with a largely closed C0 2 gas turbine cycle in a block diagram.
- the gas turbine system 16 comprises a compressor 1 and a turbine 3, which are connected to a generator 15 via a common shaft.
- the gas turbine system 16 further comprises a combustion chamber 2, a cooler and / or waste heat processor 4, a water separator 5 and a removal point 6 for CO 2 removal.
- a fuel 7 in the form of a hydrocarbon for example a natural gas with the main component methane, is subjected to an internal combustion in an atmosphere prepared from oxygen 8, carbon dioxide and possibly water.
- the water as shown in FIG. 1, can be condensed out in the water separator 5.
- the excess carbon dioxide can be separated off largely purely.
- the carbon dioxide can then be deposited in a suitable manner so that practically no carbon dioxide is released into the atmosphere.
- none or only part of the water can be condensed out in the water separator 5, so that a carbon dioxide / water mixture is removed at the extraction point 6.
- the oxygen 8 required for the combustion of the fuel 7 is generated in an air separation plant 9 from intake air 10.
- Residual gases 11 in the form of nitrogen (N 2 ) and argon (Ar), which are produced as waste products, can either be released into the atmosphere or used for other purposes.
- the steam 17 generated in the cooler / waste heat processor 4 can either be used in an independent process, for example in a downstream steam turbine are, or injected into the combustion chamber 2 as injection steam 12 in order to increase the mass flow in the turbine 3 and thus increase the efficiency and efficiency of the process.
- a partial stream 13 of the steam can be used for effective cooling of thermally loaded components in the turbine 3.
- compressors 1 and turbine 3 are specially designed and designed for the requirements of the respective working medium, there is no doubt about the technical feasibility of such a process. However, for economic reasons it will be necessary to operate corresponding gas turbine systems 16 at least temporarily with compressors 1 and turbines 3, which have been modified as little as possible on the basis of existing machines designed for operation with ambient air.
- the essence of the invention is a compressor and / or the turbine (3) to be used with a rotor and a housing which largely correspond to a rotor and a housing of a compressor designed for the working medium air or a turbine designed for the working medium air.
- the adaptation to the expansion behavior of the working medium, which is different from air, is then brought about essentially by modifications of the flow channels and / or the moving blades and / or the guide grids. This makes it possible to build on existing compressors or turbines, which are then adapted to the new working medium with comparatively minor changes.
- the necessary modification is brought about in that the free flow cross sections on the high pressure side of the compressor and / or turbine are reduced in the form of blocked sectors by blocking part of the flow channels in the guide vane.
- the necessary modification is effected in that the free flow cross sections on the high pressure side of the compressor and / or turbine are reduced by inserting annular flow obstacles in the guide vents.
- the necessary modification is effected in that the free flow cross sections on the high pressure side of the compressor and / or turbine are reduced by adjustable guide grids.
- FIG. 1 shows a system diagram of an exemplary gas turbine system working with a carbon dioxide / water mixture as the working medium
- Fig. 2 shows the speed of sound in carbon dioxide / water mixtures
- Fig. 3 shows the deviation of the volume flow in% during the expansion of
- Fig. 5 shows the inner structure of a schematic representation
- FIG. 6 seen in several partial figures in the axial direction, an exemplary guide grille without modification (FIG. 6a), with a partial partial application according to an embodiment of the invention (FIG. 6b), with a partial partial application according to another embodiment of the invention (FIG. 6c ) and with adjustable guide vanes according to a further embodiment of the invention
- the compressor 1 and the turbine 3 of the gas turbine system from FIG. 1 have the internal structure shown in simplified form in FIG. 5, the high-pressure side (for the compressor 1 the outlet side, for the turbine 3 the inlet side) being on the left side of the illustration.
- the compressor 1 or the turbine 3 has a rotor 18 which can be rotated about an axis 23 and has a multi-stage blading which consists of individual sets of rotor blades 21.
- the rotor 18 with the blading is surrounded by a housing 19.
- Fixed guide vanes 20 with corresponding guide vanes are arranged between the sets of rotor blades 21.
- Flow channels 22 run between the guide vanes of the guide grids 20 in the space between the rotor 18 and the housing 19 (see also FIG. 6a).
- rotor 18 and housing 19 of a compressor 1 designed for the working medium air and / or a turbine 3 designed for the working medium air are now retained.
- carbon dioxide / water different from air essential modifications of the flow channels 22 and / or the blades 21 and / or the guide vane 20 made.
- a first possibility for modification consists in reducing the free flow cross sections on the high pressure side of compressor 1 and / or turbine 3 in that part of the flow channels 22 in the associated guide vane 20 are closed by blocked sectors 24 arranged around the circumference ( 6b; sectoral partial loading).
- a second possibility of the modification is that the free flow cross sections on the high pressure side of the compressor 1 and / or turbine 3 are reduced by inserting annular flow obstacles 25 in the guide vents 20 (FIG. 6 c; partial radial loading).
- a third possibility of the modification is that the free flow cross sections on the high pressure side of compressor 1 and / or turbine 3 are reduced by adjustable guide grids 20 with adjustable guide vanes 26 (FIG. 6d; in the figure, for the sake of simplicity, only one exemplary adjustable guide vane is shown 26, whose adjustability is indicated by the dashed lines).
- FIG. 4 shows percentage deviations between axial speeds that occur in a turbine optimized for air and axial speeds in turbines modified according to the invention operated with different carbon dioxide / water mixtures.
- the extensive adjustment of the axial speeds is gradual reduction of the available flow cross-sections in the individual stages of the turbine.
- Table 1 summarizes the cross-sectional ratios chosen for the different compositions.
- guide vanes 26 of the guide vane 20 are provided in the compressor 1 and / or turbine 3 in order to compensate for variations in the thermodynamic properties of the working medium caused by the inert gases.
- the heat sink 4 is designed to generate steam and if a partial stream 13 of the steam generated is fed to the turbine 3 for cooling thermally loaded components.
- This heat sink 4 can also be designed to generate a quantity of steam for operating a steam turbine, not shown in the drawing. The required partial stream 13 can then be branched off from this amount of steam.
