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:
- 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 heated there by combustion of a fuel supplied via the fuel supply 21.
- the resulting exhaust gas is then in the following High-pressure turbine 16 relaxed under work performance to a medium 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 points of the combustion chambers 18, 19 and turbines 16, 17 in order to limit the material temperatures to an acceptable level. That from the
- Low-pressure turbine 17 incoming exhaust gas is passed through a heat recovery steam generator
- HRSG JHeat Recovery Steam Generator
- the OTC coolers 23, 24 are part of the water-steam cycle; superheated steam is generated at their outputs.
- 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 advantages of this type of gas turbine for the plant can be utilized in a special way by using gas turbines with reheating according to FIG. 1 in an IGCC plant.
- the highest flexibility and efficiency in operating an IGCC plant can be achieved if the air separation plant is not integrated and undiluted fuels can be incinerated. This can be accomplished by means of a reheat gas turbine according to Figure 1, while at the same time keeping emissions low due to an alternative NOx control concept. This type of approach benefits from the benefits of reheat.
- the combined cycle power plant 30 of FIG. 2 includes a gas turbine 11 having a low pressure compressor 13, a high pressure downstream compressor 14 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 compressor 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.
- the nitrogen (N 2 ) which is likewise formed during the decomposition is supplied to the low-pressure combustion chamber 19 (and / or the high-pressure combustion chamber 18) via a nitrogen line 32b for dilution of the syngas.
- 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.
- N 2 Nitrogen
- CO-rich and H 2 -rich fuels are added to dilute the syngas fuels (CO-rich and H 2 -rich fuels) to control the production of NO x.
- N 2 dilution is to reduce the flame temperature or, in the case of an afterburner or reheat, reduce the inlet temperature in the second stage of combustion.
- This alternative which is possible for a reheat gas turbine, provides the opportunity to control the production of NOx without significantly sacrificing performance.
- Coal gasification plant cooperating gas turbine which is characterized by a reduction in NOx emission without significant loss of performance and flexibility of operation.
- 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 the resulting hot gases are expanded in the first turbine, and wherein in second combustion chamber syngas are burned using the gases coming from the first turbine and the resulting hot gases are expanded in the second turbine, that the two combustion chambers are operated with undiluted syngas, and that the flame temperature in the first combustion chamber of the gas turbine compared to the operation with natural gas is lowered while the second combustion chamber is driven in the natural gas designed for normal operation.
- An embodiment of the method according to the invention is characterized in that CO-rich syngas is used as the fuel and that the flame temperature in the first combustion chamber of the gas turbine is lowered by 50-100 K compared with the operation with natural gas.
- Another embodiment of the method according to the invention is characterized in that H 2 -rich syngas is used as the fuel, and that the flame temperature in the first combustion chamber of the gas turbine is lowered by 100-150 K compared with the operation with natural gas.
- Fig. 1 shows the simplified diagram of a combined cycle power plant with a
- FIG. 2 shows the simplified diagram of an IGCC plant with a gas turbine with reheat or sequential combustion, wherein the nitrogen obtained in the air separation is used for dilution of the syngas;
- FIG. 3 shows the simplified diagram of an IGCC system with a gas turbine with reheat or sequential combustion, wherein according to the invention undiluted syngas is used as fuel and the flame temperature in the first combustion chamber is reduced to reduce the NOx emission.
- FIG. 3 shows, in a greatly simplified scheme, an IGCC system with a gas turbine with reheat or sequential combustion, which is operated according to the invention.
- the same reference numerals are used for the same system parts, as in FIG. 2.
- the nitrogen (N 2 ) obtained in the air separation unit 32 is no longer used here for diluting the syngas used as fuel, but the syngas is fed into the combustion chambers 18 undiluted, 19 injected.
- the flame temperature T F with respect to the normal
- Natural gas operating prevailing temperature T NG lowered, while in the second combustion chamber 19 provided for natural gas operation nominal flame temperature T NG is maintained.
- T NG nominal flame temperature
- the generation of NOx can be controlled without a significant loss of power occurring.
- a gas turbine without reheat or sequential combustion by lowering the flame temperature in the (single combustion chamber) by 100 0 C results in a reduction of power by 10% and a reduction in efficiency by 1%, while lowering the flame temperature in the first combustion chamber of a gas turbine with sequential combustion causes a reduction in power by only about 1% and a reduction in efficiency by only 0.1%.
- the size of the lowering of the flame temperature T F in the first combustion chamber 18 depends on the type of syngas used:
- Natural gas operation is. Therefore, there is no loss of power and efficiency for the combined cycle process of the IGCC plant.
- This is a special feature of the reheat gas turbine where the flame is controlled with the inlet conditions instead of the outlet conditions.
- the system can therefore be operated with the following advantages: o
- the lack of syngas dilution leads to a lower difference in calorific value between natural gas and undiluted syngas compared to dilute syngas.
- the operating concept for the gas turbine is simple and flexible.
- the operation of the entire plant is flexible because of the lack of integration of the air separation plant 32.
- the gas turbine's unchanged outlet temperature results in high performance and high efficiency for the IGCC plant.
- the turbine outlet temperature of the gas turbine is the same as in natural gas operation.
- the superheated gas turbine is an advantage in terms of NOx emission inherent in syngas applications through the optimal choice of combustion temperatures in the two combustion chambers. 2. The combustion stability and operational flexibility of the
- Gas turbines with reheat are larger than in a comparable single-stage combustion engine. Operating limits are typically given by flame extinction and flashback and / or emission levels at a given flame temperature, which is one allowed
- Burning system is injected, which typically operates at a pressure of> 30 bar or in the range of 15-20 bar. LIST OF REFERENCE NUMBERS
