Description
- This application is a continuation of U.S. application Ser. No. 12/076,689, which is a division of U.S. application Ser. No. 11/657,661, filed on Jan. 25, 2007.
- This invention relates to power augmentation of combustion turbine power systems with compressed air energy storage and additional expander; and, more particularly, to augmenting power of the system by expanding heated, high pressure compressed air from a storage for producing additional expander power and extracting airflow from the expander and injecting the extracted airflow into the combustion turbine upstream of combustors for combustion turbine power augmentation.
- It is well known that combustion turbines have significant power degradation associated with increased ambient temperature or high elevations. This loss of power is primarily associated with the reduced mass of the combustion turbine's airflow, caused by the reduced inlet air density.
- There are a number of power augmentation technologies targeting the recovery of the power lost by combustion turbines due to high ambient temperatures/high elevation:
-
- The Air Injection power augmentation technology that is based on the injection upstream of combustors of additional airflow (humid or dry) that is delivered by external auxiliary compressor(s);
- Inlet chillers that cool the ambient air and provide a corresponding power augmentation;
- Evaporative coolers, inlet fogging and “wet compression” technologies that provide power augmentation by a combination of the inlet air cooling and the increased mass flow through the combustion turbine;
- Air Injection power augmentation technology disclosed in my earlier U.S. Pat. No. 5,934,063, the contents of which is incorporated by reference herein, that is based upon air injection upstream of combustors using a compressed air energy storage. However, the compressed air in the storage typically has a much higher pressure than is needed for the air injection for the power augmentation.
- Thus, there is a need to utilize the compressed air storage high pressure to further improve the incremental power and to improve the overall heat rate of the system.
- An object of the invention is to fulfill the need referred to above. In accordance with the principles of the present invention, this objective is achieved by providing a combustion turbine power generation system including a combustion turbine assembly including a main compressor constructed and arranged to receive ambient inlet air, a main expansion turbine operatively associated with the main compressor, combustors constructed and arranged to receive compressed air from the main compressor and to feed the main expansion turbine, and an electric generator associated with the main expansion turbine for generating electric power. A compressed air storage stores compressed air. A heat exchanger is constructed and arranged to receive a source of heat and to receive compressed air from the storage so as to heat compressed air received from the storage. An air expander is associated with the heat exchanger and is constructed and arranged to expand the heated compressed air to exhausted atmospheric pressure for producing additional electric power via an electric generator associated with the expander and to permit only a portion of airflow expanded by the air expander to be injected, under certain conditions, into the combustion turbine assembly.
- In accordance with another aspect of the invention, a method is provided to augment power of a combustion turbine assembly. The combustion turbine assembly includes a main compressor constructed and arranged to receive ambient inlet air, a main expansion turbine operatively associated with the main compressor, combustors constructed and arranged to receive compressed air from the main compressor and to feed the main expansion turbine, and an electric generator associated with the main expansion turbine for generating electric power. The method provides stored compressed air from a compressed air storage. The compressed air originating from the storage is heated. The heated, compressed air is expanded in an air expander to exhausted atmospheric pressure for producing additional power. The air expander is constructed and arranged to permit only a portion of airflow expanded by the air expander to be injected, under certain conditions, into the combustion turbine assembly. Additional electric power is generated, via an electric generator, using air expanded by the air expander.
- Other objects, features and characteristics of the present invention, as well as the methods of operation and the functions of the related elements of the structure, the combination of parts and economics of manufacture will become more apparent upon consideration of the following detailed description and appended claims with reference to the accompanying drawings, all of which form a part of this specification.
- The invention will be better understood from the following detailed description of the preferred embodiments thereof, taken in conjunction with the accompanying drawings, wherein like reference numerals refer to like parts, in which:
-
FIG. 1 is a schematic illustration of a combustion turbine power generation system with power augmentation using a compressed air storage supplying compressed air, preheated in a heat exchanger, to an expander that expands the air for providing additional power with expander exhaust airflow being injected upstream of the combustors, provided in accordance with the principles of the present invention. -
FIG. 2 is a schematic illustration of a combustion turbine power generation system with power augmentation using a compressed air storage supplying compressed air, preheated in a heat exchanger, to an expander that expands the air for providing additional power with airflow extracted from a stage of the expander being injected upstream of the combustors, provided in accordance with the principles of another embodiment of the present invention. - With reference to
FIG. 1 , a combustion turbine power generation system with power augmentation, generally indicated as 10, is shown in accordance with an embodiment of the present invention. Thesystem 10 includes a conventional combustion turbine assembly, generally indicated at 11, having amain compressor 12 receiving, atinlet 13, a source of inlet air at ambient temperature andfeeding combustors 16 with the compressed air; a main expansion turbine 14 operatively associated with themain compressor 12, with thecombustors 16 feeding the main expansion turbine 14, and anelectric generator 15 for generating electric power. - A
compressed air storage 18 is provided that is preferably an underground storage structure that stores air that is compressed by at least oneauxiliary compressor 20. In the embodiment, theauxiliary compressor 20 is driven by amotor 21, but can be driven by an expander or any other source. Theauxiliary compressor 20 charges thestorage 18 with compressed air during off-peak hours. Anoutlet 22 of thestorage 18 is preferably connected with aheat exchanger 24. Theheat exchanger 24 also receivesexhaust air 25 from the main expansion turbine 14. Instead, or in addition to theexhaust air 25 from the main turbine 14, theheat exchanger 24 can receive any externally available source of heat. - An
outlet 26 of theheat exchanger 24 is connected to anexpander 28 that is connected to anelectric generator 30. In accordance with the embodiment, during peak hours, compressed air is withdrawn from thestorage 18, preheated in theheat exchanger 24 and sent to theexpander 28. The heated air is expanded though theexpander 28 that is connected to theelectric generator 30 and produces additional power. The exhaust from theexpander 28, with injection flow parameters determined by combustion turbine limitations and optimization, is injected into thecombustion turbine assembly 11 upstream ofcombustors 16. Thus, as shown inFIG. 1 ,structure 32 communicates withstructure 35 to facilitate the injection of air. In the embodiment, thestructures - Typical gross power augmentation of a combustion turbine associated with an air injection technology is 20-25%. The additional power of the
additional expander 28, operating with the injection airflow of approximately 12-14% (of the combustion turbine assembly inlet flow) and utilizing a stored compressed air with the inlet pressure of approximately 60-80 bars (a typical stored compressed air pressure) preheated in theheat exchanger 24 to the inlet temperature of approximately 480-500 C, is approximately 5-10% of thecombustion turbine assembly 11 power. As an example, the GE 7241 combustion turbine assembly operating at 35 C could have gross power augmentation of approximately 38-40 MW with the air injection flow of approximately 12% of the combustion turbine assembly inlet flow; the expander 28 additional power is approximately 10 MW with the total power augmentation of approximately 48-50 MW. Thepower generation system 10 heat rate is reduced because theadditional expander 28 power is delivered without any additional fuel flow, i.e. with the zero heat rate. - This
system 10 has the following additional (to original embodiment with acombustion turbine assembly 11;compressed air storage 18 and charging compressor 20) components: -
- The additional air expander 28
- The
heat exchanger 24 recovering the combustion turbine 14 exhaust heat and feeding theexpander 28 - BOP piping and specialties
- The overall parameters of the
system 10 are optimized based on the overall plant economics including: -
- Additional components capital and operational costs
- The combustion turbine power augmentation
- The expander 28 additional peaking power produced
-
FIG. 2 shows another embodiment of thesystem 10′ that is similar to that ofFIG. 1 , except that theadditional expander 28 expands the preheated compressed stored air from the stored air pressure to atmospheric pressure resulting in much higher power. In addition, the expander flow rate is not restricted to the injection rate allowable by a specific combustion turbine assembly. Furthermore, the air required for the injection in a combustion turbine assembly for power augmentation with specific parameters is extracted from theexpander 28 with specific parameters. - With reference to
FIG. 2 , the compressed air from thestorage 18 is directed to theheat exchanger 24 that receives heat from the source of a heat (e.g. exhaust of turbine 14). The heated air is expanded though theexpander 28 that is connected to theelectric generator 30 and produces additional power. The airflow ofexpander 28 is a subject for optimization and could be as high as a combustion turbine inlet flow. Theexpander 28 has a provision for an extracted airflow flow with parameters consistent with the requirements of the air injection technology determined by combustion turbine assembly limitations and can be a subject of optimization. In other words, the injection flow parameters of the injected airflow are consistent with flow parameters of themain compressor 12 at an injection point. Thus, injection can be limited or restricted under certain conditions. For example, based on combustion turbine manufacturer published data, injection at low ambient temperatures may not be permitted or possible, or injection may not be permitted or possible due to accessibility to injection points, or injection may not occur due to operational judgments. The extracted airflow is injected viastructure 33 into the combustion turbine assembly 11 (via structure 35) upstream of thecombustors 16 with a combustion turbine power augmentation of approximately up to 20-25%. The remaining airflow in theexpander 28 is expanded though low pressure stages to atmospheric pressure. Thus, when injection is possible or desired, not all airflow from the expander is exhausted to atmospheric pressure. - As an example, the GE 7241 combustion turbine operating at 35 C could have gross power augmentation of approximately 38-40 MW with the extracted (from the additional expander 28) and injected airflow of approximately 12% of the combustion turbine inlet flow; the expander additional power could be as high as the combustion turbine power and is a subject for optimization.
- The use of the
expander 28 can be employed in a Combustion Turbine/Combined Cycle Power Plant. This system preferably includes the following additional (to thecombustion turbine assembly 11; compressedair storage 18 and charging compressor 20) components: -
- The
air expander 28, -
Heat exchanger 24 recovering the combustion turbine - 14 Exhaust heat and feeding the
expander 28, - BOP piping and specialties
- The
- The foregoing preferred embodiments have been shown and described for the purposes of illustrating the structural and functional principles of the present invention, as well as illustrating the methods of employing the preferred embodiments and are subject to change without departing from such principles. Therefore, this invention includes all modifications encompassed within the spirit of the following claims.
