Definitions
- 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.
- 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 for producing additional electric power. Airflow is extracted from the expander and is injected into the combustion turbine assembly upstream of the combustors with injection flow parameters of the injected airflow being consistent with flow parameters of the main compressor at the injection point.
- a compressed air storage 18 is provided that is preferably an underground storage structure that stores air that is compressed by at least one auxiliary compressor 20 .
- the auxiliary compressor 20 is driven by a motor 21 , but can be driven by an expander or any other source.
- the auxiliary compressor 20 charges the storage 18 with compressed air during off-peak hours.
- An outlet 22 of the storage 18 is preferably connected with a heat exchanger 24 .
- the heat exchanger 24 also receives exhaust air 25 from the main expansion turbine 14 . Instead, or in addition to the exhaust air 25 from the main turbine 14 , the heat exchanger 24 can receive any externally available source of heat.
- An outlet 26 of the heat exchanger 24 is connected to an expander 28 that is connected to an electric generator 30 .
- compressed air is withdrawn from the storage 18 , preheated in the heat exchanger 24 and sent to the expander 28 .
- the heated air is expanded though the expander 28 that is connected to the electric generator 30 and produces additional power.
- the exhaust from the expander 28 with injection flow parameters determined by combustion turbine limitations and optimization, is injected into the combustion turbine assembly 11 upstream of combustors 16 .
- structure 32 communicates with structure 35 to facilitate the injection of air.
- the structures 32 and 35 are preferably piping structures.
- 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 the heat exchanger 24 to the inlet temperature of approximately 480-500 C, is approximately 5-10% of the combustion turbine assembly 11 power.
- 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.
- the power generation system 10 heat rate is reduced because the additional 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 a combustion turbine assembly 11 ; compressed air storage 18 and charging compressor 20 ) components:
- the overall parameters of the system 10 are optimized based on the overall plant economics including:
- FIG. 2 shows another embodiment of the system 10 ′ that is similar to that of FIG. 1 , except that the additional expander 28 expands the preheated compressed stored air from the stored air pressure to atmospheric pressure resulting in much higher power.
- the expander flow rate is not restricted to the injection rate allowable by a specific combustion turbine assembly.
- the air required for the injection in a combustion turbine assembly for power augmentation with specific parameters is extracted from the expander 28 with specific parameters.
- the compressed air from the storage 18 is directed to the heat exchanger 24 that receives heat from the source of a heat (e.g. exhaust of turbine 14 ).
- the heated air is expanded though the expander 28 that is connected to the electric generator 30 and produces additional power.
- the airflow of expander 28 is a subject for optimization and could be as high as a combustion turbine inlet flow.
- the expander 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. In other words, the injection flow parameters of the injected airflow are consistent with flow parameters of the main compressor 12 at an injection point.
- the extracted airflow is injected via structure 33 into the combustion turbine assembly 11 (via structure 35 ) upstream of the combustors 16 with a combustion turbine power augmentation of approximately 20-25%.
- the remaining airflow in the expander 28 is expanded though low pressure stages to atmospheric pressure.
- the additional power of the expander is a subject of optimization and could be equal to a combustion turbine power.
- 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 the combustion turbine assembly 11 ; compressed air storage 18 and charging compressor 20 ) components:
