6 FAQs about [Energy storage nozzle working pressure]
How many nozzles are regulated in a compressed air energy storage system?
Only one nozzle is regulated in the optimal regulation process. The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process. In order to make the turbine work efficiently in non-design conditions, it is necessary to adopt a reasonable air distribution method for the turbine.
How many nozzles should be regulated in an optimal nozzle governing method?
An optimal nozzle governing method should contain as few nozzles as possible. More throttle valves should be fully open for the optimal method. Only one nozzle is regulated in the optimal regulation process. The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process.
Can a compressed air energy storage system achieve pressure regulation?
In this paper, a novel scheme for a compressed air energy storage system is proposed to realize pressure regulation by adopting an inverter-driven compressor. The system proposed and a reference system are evaluated through exergy analysis, dynamic characteristics analysis, and various other assessments.
How should axial turbine nozzles be designed?
Unlike the traditional chamber design method, when exploring the nozzle governing characteristics of the axial turbine, to prevent the mixing loss caused by the air pressure difference between adjacent nozzles, the chamber should be designed separately, corresponding to a certain number of nozzle stators.
What is nozzle governing?
When nozzle governing is adopted in the system, the throttle valves are regulated, respectively. In this mode, the admission air is redistributed, and its thermodynamic process is shown in Fig. 2 (b). Nozzle governing can reduce the throttling loss and improve the turbine's total efficiency, such as in industrial steam turbine power plants .
How to optimize nozzle inlet pressure under variable woutput conditions?
Based on the RS model, the multi-island genetic algorithm (MIGA) is used to obtain the optimal nozzle inlet pressure under variable Woutput conditions with the maximum specific work ( w) as the optimization objective, and finally the optimization strategy of NG is derived.
