Definitions
- This invention relates to a Compressed Air Energy Storage (CAES) system and, more particularly, to a CAES system that provides improved performance as compared to conventional CAES systems.
- CAES Compressed Air Energy Storage
- U.S. Patent No. 4,872,307 is based on the utilizing two combustion turbine assemblies.
- One combustion turbine assembly 10 has a debladed turbine or expander 1 2 and is practically converted into a low pressure compressor 14 driven by a motor 15.
- the second combustion turbine assembly 1 6 has a debladed compressor 18 and is practically converted into a turbine 20 with double the combustion turbine power driving an electric generator 22.
- An auxiliary compressor 24, driven by motor 25, is provided to, in addition to compressor 14, charge the air storage 26 at an optimized maximum pressure.
- the air storage 26 stores compressed air when off-peak energy is stored in the form of compressed air energy.
- the electric generator/motor driven compressor 14 of first combustion turbine assembly 10 with debladed turbine 1 2, and motor- driven auxiliary compressor 24 utilize available energy and convert it into the energy of the compressed air stored in the air storage 26.
- the compressed air is withdrawn from the air storage 26 and is directed to the combustor associated with turbine 20 of the second combustion turbine assembly 1 6 to produce power.
- U.S. Patent No. 4,872,307 thus provides a power system that uses a plurality of modified combustion turbine assemblies along with additional equipment to provide a CAES system. Although this conventional CAES system is effective, there is a need to further modify this system to provide increased performance and operational flexibility.
- An object of the invention is to fulfill the needs referred to above.
- this objective is fulfilled by a method that provides a Compressed Air Energy Storage (CAES) system based on first and second combustion turbine assemblies.
- the method provides a first combustion turbine assembly having a debladed turbine element, a compressor, and a generator/motor for driving the compressor.
- Compressed air from an outlet of the compressor communicates with air storage, preferably via and auxiliary compressor, instead of with the turbine element.
- a second combustion turbine assembly has a debladed compressor, a combustor, a turbine associated with the combustor, and a generator associated with the turbine.
- Compressed air from the air storage communicates directly with the combustor upstream of the turbine of the second combustion turbine assembly instead of with air from the compressor of the second combustion turbine assembly so that the turbine can expand the compressed air from the air storage to produce electrical power via the generator without any reduction in power since the compressor of the second combustion turbine assembly is not driven.
- An additional expander and an additional generator associated with the expander are provided.
- the method ensures that compressed air from the air storage can be preheated and then can communicate with the expander, in addition to directly communicate with the combustor and thus the turbine of the second combustion turbine assembly, and ensures that airflow from the expander can communicate with the combustor and thus the turbine of the second turbine assembly, so that the additional expander can expand the preheated compressed air to produce electrical power via the additional generator, in addition to the electrical power produced by the generator of the second combustion turbine assembly.
- a portion of airflow from the expander can be extracted and injected upstream of the combustor of the second combustion turbine assembly and the expander can expand the preheated compressed air to atmospheric pressure.
- all exhaust airflow from the expander can be provided upstream of the combustor of the second combustion turbine assembly.
- Figure 1 is a view of a conventional CAES system as disclosed in U.S.
- Figure 2 is a view of a CAES system as disclosed in co-pending application No. 1 2/582,720 having an additional expander for additional power generation.
- Figure 3 is a CAES system provided in accordance with a first embodiment thereof.
- Figure 4 is a CAES system provided in accordance with a second embodiment thereof.
- FIG. 2 shows a second generation CAES system, generally indicated at 28, from my co-pending patent Application No. 1 2/582,720, the content of which is hereby incorporated into this specification by reference.
- a compressor 30 supplies compressed air to an air storage 32 during off-peak hours and, during peak hours, the stored compressed air is withdrawn from the air storage 32, is preheated by utilizing the exhaust gas heat of the combustion turbine 34, and then is directed into an expander 36 that generates the preheated compressed air power in addition to combustion turbine power.
- a CAES system is shown, generally indicated as 40, in accordance with an embodiment.
- the system 40 includes a first combustion turbine assembly, generally indicated as 42, having a compressor 44 receiving a source of inlet air and a turbine element 46 that is initially debladed since such turbine element is not to be utilized for the production of energy. Consequently, no fuel will be supplied to combustor 48 during this energy absorbing compression stage.
- an externally located additional thrust bearing 50 is installed on shaft 52.
- Shaft 52 serves to transmit rotational energy from a synchronous electrical generator/motor, illustratively, motor 54, to debladed turbine element 46, compressor 44 and thrust bearing 50.
- a compressor discharge flange (not shown) is typically provided in the compressor of a conventional combustion turbine assembly to direct compressed air to combustor 48.
- such compressed air input to combustor 48 is removed and the compressed air is directed to an intercooler 56 via interconnection 58.
- intercooler 56 In addition to the above modification to combustion turbine assembly 42, intercooler 56, a high pressure compressor 60, driven by motor 62, and an aftercooler 64 are provided to complete the compression train.
- High pressure compressor 60 further compresses the air from compressor 44 which functions as a lower pressure compressor.
- High pressure compressor 60 is preferably driven through clutch 66 by motor 62.
- high pressure compressor 60 may be driven by motor 54.
- Aftercooler 64 is provided to cool the compressed air exiting high pressure compressor 60 before entering the air storage 66.
- the air storage 66 is preferably underground air storage such as a geological structure.
- the air storage can be an above-ground pressure vessel.
- compressed air is preferably stored in the air storage 66, the compressed air can be converted into a liquid air and stored in the air storage 66. When needed, the liquid air can then be converted back to compressed air and used in the system 40.
- the system 40 includes a second combustion turbine assembly, generally indicated at 68, that comprises a turbine 70 and a compressor 72 connected to a shaft 74.
- Clutch devices 76, 78 are provided in the combustion turbine assembly 68 for isolating compressor 72, turbine 70 and a gas turbine generator 80.
- Compressor 72 is initially debladed since such compressor is not to be utilized for the compression of air.
- additional thrust bearing 82 is installed on shaft 74.
- Shaft 74 serves to transmit rotational energy from turbine 70 to a synchronous electrical machine, illustratively, generator 80, debladed compressor 72, and thrust bearing 82.
- valve 86 and associated interconnection 87 are placed between the combustor 84 and the air storage 66.
- Valve 86 and air storage 66 serve as a compressed air source for the combustor 84, in place of compressor 72.
- the conventional combustion turbine assembly is ordinarily coupled to an electrical power generator of predetermined capacity.
- the electrical generator of the conventional combustion turbine assembly is removed and replaced by an electrical generator 80 of approximately double capacity since combustion turbine assembly 68 has approximately twice its original output once the compressor is debladed.
- the CAES system 40 with a single generator outputs approximately the same power as the combined efforts of the two gas turbines each having its own generator, from which it was constructed.
- compressed air is stored underground with the maximum pressure of 1 200 psia and most often over 2500 psia, with a significant energy used for the ambient air compression and directed to the compressed air storage at this pressure. These pressures are much higher than the combustion turbine assembly's combustor/turbine inlet pressure of approximately 1 70- 190 psia. Thus, the stored compressed air should be throttled from 1200 psia to 170-1 90 psia. However, such throttling results in the loss of a significant amount of compression energy. [0030] In accordance with the embodiments, compression energy is used by an additional expander 88 provided in the system 40.
- an inlet to the expander 88 is coupled with the outlet of the air storage 66 via interconnection 90 in the form of piping or the like.
- compressed air from an outlet of the motor driven additional compressor 60 charges the air storage 66.
- compressed air is withdrawn from the air storage 66 at specific pressure and is routed through flow control and pressure reducing valve 86 to combustor 84 upstream of the turbine 70 instead of with air from the compressor 72.
- the combustor 84 combines the compressed air with a fuel and combusts the result to produce a hot gas that drives the turbine 70 connected to the generator 80 to produce electrical power without any reduction in power since compressor 72 is not driven.
- compressed air is routed from the air storage 66 through flow control valve 98, is preheated in a recuperator 92 that utilizes the exhaust gas heat of turbine 70, or any other heat source, and is expanded through the green power generation expander 88 driving an electric generator 94 to produce additional electrical power.
- the expander 88 has air extraction via interconnection 96 and through valve 1 00 to supply the extracted air upstream of the combustor 84 at specific inlet pressure and flow parameters. The remaining airflow is expanded in the low pressure part of the expander 88 to the atmospheric pressure generating the additional green electrical power.
- a combustor or duct burner 1 02 can be provided for burning fuel to heat air that is expanded in expander 88.
- FIG 4 shows another embodiment of a CAES system, generally indicated at 40'.
- the system 40' is substantially similar to the system 40 of Figure 3, with compressed air being withdrawn from the air storage 66 at specific pressure, being preheated in the recuperator 92 that utilizes the exhaust gas heat from turbine 70, or any other heat source, and expanded through the green power generation expander 88 driving the electric generator 94.
- all exhaust airflow of expander 88 is provided upstream of the combustor 84, via interconnection 96' and through valve 1 00, at specific inlet pressure and flow parameters.
- Table 1 shows a summary of the performance characteristics of the system of U.S. Patent No. 4,872,307 as shown in Figure 1 , the system of Application No. 1 2/582,720 shown in Figure 2, and the two embodiments, Figure 3 and Figure 4. This table indicates very significant performance improvements of the embodiments of Figures 3 and 4.
