Energy storage container spraying

What is spray-type packed bed thermal energy storage technology?

A new spray-type packed bed thermal energy storage technology is proposed. Liquid holdup inside spray-type packed bed can be minimized to 0.1. The practicability of spray-type packed bed thermal storage technology is verified. The cost of spray-type packed bed can be below 13.0 $/kWh.

How is heat stored in a spray-type packed bed?

The heat storage in a spray-type packed bed is accomplished when the temperatures at the inlet and outlet are the same.

How does water spray energy consumption affect the isothermal compression system?

The water spray energy consumption also increased from 2.48 J/Stroke to 17.55 J/Stroke, accounting for about 10 % of the total energy consumption of the isothermal compression system. The effects of spray angle, nozzle diameter and spray water pressure on the isothermal compression system were comprehensively considered.

How much energy does a spray water pressure atomizing nozzle use?

Spray water pressure. This paper uses a high-pressure atomizing nozzle to atomize water into micron-level fine water mist. Through single variable analysis and water mist measurement results, it can be seen that when the spray water pressure is higher than 7 MPa, the energy consumed by the water mist has accounted for 40 % of the compression work.

What is compressed air energy storage?

Compressed air energy storage is a promising medium- and long-term energy storage method, and can be used as a large-scale energy storage system to provide a feasible solution for the commercialization of energy storage. Compressed air energy storage technology has the advantages of large energy storage scale, long life, and pollution-free [ 6 ].

What is water spray kinetic energy?

Because the high-speed movement of the water stream produces spray after passing through the nozzle, the kinetic energy of the water stream is defined as the energy consumption of the water spray.
