Principle of the water adding device for steam energy storage tank

What are the components of a steam accumulator?

Water: Partially fills the vessel, serving as the medium for storing energy. Steam Inlet and Outlet: Pipes that allow steam to enter and exit the accumulator. Pressure and Temperature Controls: Devices to monitor and regulate internal conditions.

How does a steam accumulator work?

The working principle of a steam accumulator revolves around its role as a storage and balancing mechanism in steam systems. Here’s a breakdown of how it operates: Pressure Vessel: A robust container, often cylindrical and insulated, designed to withstand high pressure. Water: Partially fills the vessel, serving as the medium for storing energy.

How does a steam accumulator charge?

Charging of an accumulator takes place when ‘surplus’ or ‘excess’ steam from the boiler is condensed in the water space of the accumulator. This is achieved by directly injecting the steam into the water by means of special charging nozzles.

What happens when a water tank is discharged?

During discharge, saturated steam is removed from the upper part of the tank. Due to the withdrawal of saturated steam, the pressure in the storage volume decreases and part of the water is evaporated to steam. Flashing takes place in the entire water volume.

How does a steam accumulator differ from a tank storage system?

Steam accumulators also differ in operating behavior from two tank storage concepts; most systems deliver steam at sliding pressure during discharge, and exergetic efficiency is limited. There is a strong dependence between storage density and the pressure reduction that is possible during discharge.

How does a water storage tank work?

In the charged state, the tank is filled with high-temperature pressurized water; at the end of the discharge process, the water in the storage tank is cold. During the discharge process, hot water is withdrawn at the top, and cold water is injected at the bottom to replace the withdrawn hot water.
