Definitions
- the present invention relates to the field of power plant technology. It relates to a method for operating a (stationary) gas turbine according to the preamble of claim 1, as well as a gas turbine for carrying out the method.
- a reheat gas turbine gas turbine is known (see eg US-A-5,577,378 or "State-of-the-art gas turbines - a letter update", ABB Review 02/1997, Fig. 15, turbine type GT26 ), which combines flexible operation with very low exhaust emissions.
- the machine architecture of the gas turbine type GT26 is unique and is ideally suited to the realization of a concept, which is the subject of the present invention, because: - there is already a significant diversion of compressor air at medium compressor pressures,
- the principle of the known gas turbine with reheat is shown in Fig. 1.
- the gas turbine 11, which is part of a combined cycle power plant 10, comprises two compressors connected in series on a common shaft 15, namely a low-pressure compressor 13 and a high-pressure compressor 14, and two combustion chambers, namely a high-pressure combustion chamber 18 and a reheat combustion chamber 19, and associated turbines, namely one High pressure turbine 16 and a low pressure turbine 17.
- the shaft 15 drives a generator 12 at.
- Air is sucked in via an air inlet 20 from the low-pressure compressor 13 and first compressed to an intermediate pressure level (about 20 bar).
- the high pressure compressor 14 then further compresses the air to a high pressure level (about 32 bar).
- OTC Once Through Cooler
- the remaining air from the high-pressure compressor 14 is guided to the high-pressure combustion chamber 18 and fed there by combustion via the fuel supply 21 Fuel heated up.
- the resulting exhaust gas is then expanded in the subsequent high-pressure turbine 16 under work to an average pressure level.
- the exhaust gas in the reheat combustor 19 is reheated by combustion of a fuel supplied via the fuel supply 22 before it is expanded in the subsequent low-pressure turbine 17 under further work.
- the cooling air flowing through the cooling lines 25, 26 is injected at suitable locations of the combustion chambers 18, 19 and turbines 16, 17 to the
- the exhaust gas coming from the low-pressure turbine 17 is passed through a heat recovery steam generator
- HRSG Heat Recovery Steam Generator
- the OTC coolers 23, 24 are part of the water-steam cycle; superheated steam is generated at their outputs.
- Burns in the combustion chambers 18 and 19 is achieved a great flexibility in operation; the combustion chamber temperatures can be adjusted so that the maximum efficiency is achieved within the existing limits.
- the low emissions of the sequential combustion system are due to the inherently low levels of emissions that can be achieved during reheat (under certain conditions, the second combustion even results in NOx consumption).
- the present invention is based on the recognition that the use of gas turbines with reheating in an IGCC plant, the advantages of this type of gas turbine for the system can be made useful in a special way.
- a gas turbine is used with reheat, comprising two combustion chambers and two turbines, burned in the first combustion chamber syngas using the compressed air and relaxes the resulting hot gases in the first turbine be burned in the second combustion chamber syngas using the gases coming from the first turbine and the resulting hot gases are expanded in the second turbine, and the resulting in the air separation nitrogen gas turbine for compression is fed back.
- the addition of the comparatively cold nitrogen to the compressor cools the compressor air and results in a type of compressor intercooling associated with all the advantages of such intercooling.
- the temperature in the Compressor lowers, which leads to a reduction in the amount of cooling air required or the additional cooling of the cooling air can be unnecessary.
- An embodiment of the inventive method is characterized in that the gas turbine comprises a first compressor for compressing sucked air to a first pressure stage and a second compressor for further compression of the air from the first pressure stage to a second, higher pressure stage, that part of the The first coming of the compressor air is decomposed into oxygen and nitrogen, and that the nitrogen resulting from this decomposition is supplied to the second compressor for compression.
- the nitrogen is preferably first pre-compressed in another compressor before it is fed to the second compressor.
- the precompressed nitrogen can be fed in particular to the inlet of the second compressor.
- the gas turbine comprises a first compressor for compressing sucked air to a first pressure stage and a second compressor for further compression of the air from the first pressure stage to a second, higher pressure stage, that part of from the first compressor coming air is decomposed into oxygen and nitrogen, and that the nitrogen resulting from this decomposition is supplied to the first compressor for compression.
- the nitrogen can be supplied to the first compressor at an intermediate stage. It can alternatively be supplied to the input of the first compressor.
- An embodiment of the gas turbine according to the invention is characterized in that two compressors connected in series are provided, that the Nitrogen line is returned to the second compressor, and that in the nitrogen line another compressor is arranged.
- the nitrogen line may be returned to the input of the second compressor.
- Another embodiment is characterized in that two compressors are connected in series, and that the nitrogen line is returned to the first compressor, either to the input of the first compressor or to an intermediate stage of the first compressor.
- the air separation plant has on the output side an oxygen line for discharging the oxygen produced during the separation, which is led to a plant for the production of syngas by means of coal gasification, wherein a Syngaszutechnisch transported syngas produced by the plant for the production of syngas to the combustion chambers.
- Fig. 1 shows the simplified diagram of a combined cycle power plant with a
- FIG. 2 is a simplified schematic of an IGCC plant with a reheat gas turbine or sequential combustor suitable for practicing the invention
- Fig. 3 shows a first embodiment of the inventive
- Fig. 4 shows a second embodiment of the inventive
- FIG. 2 shows in a greatly simplified scheme an IGCC system with a reheat gas turbine or sequential combustion gas, as is suitable for realizing the invention.
- the combined cycle power plant 30 comprises a gas turbine 11 with a low-pressure compressor 13, a subsequent high-pressure compressor 14, a high-pressure combustion chamber 18 with a subsequent high-pressure turbine 16 and a reheat combustion chamber 19 with a subsequent low-pressure turbine 17.
- the compressors 13, 14 and the turbines 16, 17 sit on a common Shaft 15, from which a generator 12 is driven.
- the combustion chambers 18 and 19 are supplied via a Syngaszutechnisch 31 with syngas as fuel, which is produced by gasification of coal (coal feed 33) in a coal gasification plant 34.
- the coal gasification plant 34 is followed by a cooling device 35 for the syngas, a purification plant 36 and a CO2 separator 37 with a CO 2 outlet 38 for discharging the separated CO 2 .
- oxygen (O 2) is used, which is obtained in an air separation plant 32 and supplied via an oxygen line 32 a.
- the air separation plant 32 receives compressed air from the outlet of the low-pressure compressor 13.
- Der in the Disassembly also resulting nitrogen (N 2 ) is supplied, for example via a nitrogen line 32 b of the low-pressure combustion chamber 19.
- condensed cooling air is tapped at the outputs of the two compressors 13 and 14, cooled in a downstream OTC cooler 23 and 24, and then via corresponding cooling lines 25 and 26 fed to the bodies to be cooled.
- a heat recovery steam generator 27 is arranged, which is part of a water-steam cycle together with a connected steam turbine 29.
- the exiting from the heat recovery steam generator 27 exhaust gas is discharged via an exhaust pipe 28 to the outside.
- Nitrogen line 32 b is fed into the high-pressure compressor 14 and compressed there.
- an additional compressor 39 is connected in the nitrogen line 32b, which compresses the nitrogen.
- the nitrogen is added directly to the inlet of the high pressure compressor 14. But it is also conceivable that it is introduced at an intermediate stage in the high pressure compressor 14.
- the nitrogen coming from the air separation plant 32 is fed via the nitrogen line 32b in the low pressure compressor 13, either in an intermediate stage (solid line in Fig. 4), or directly to the input of the low pressure compressor ( dashed line in Fig. 4). A pre-compression is not necessary in these cases.
- the resulting nitrogen in the air separation which has a relatively low temperature, is returned to the compressor, either o to the input of the compressor, or o to an intermediate stage, which is lower than the intermediate stage, on which the air has been diverted, or o exactly at the intermediate stage where the air has been diverted.
