Description

Technical Field

[0001] The utility model belongs to the technical field of stepped hot water storage, in particular to a stepped hot water storage device for power plants. Background Art

[0002] The stepped hot water storage device for power plants is mainly used to improve the operational flexibility and efficiency of thermal power plants, especially to achieve heat and electricity decoupling during the heating season. When electricity demand is at a low point, the output of boilers and turbines is reduced and stored hot water is used to supplement heating, thereby optimizing energy use and maintaining the stability of the heating system. Through effective thermal energy storage and management, energy waste is reduced and overall energy utilization efficiency is improved.

[0003] However, the water used in power plants will contain a large amount of impurities and suspended solids. If they are not isolated and treated, the pipes may be blocked after long-term use, which will not only make the device unable to operate normally or even damage it, but also consume a lot of resources and cause unnecessary waste. Therefore, we proposed a stepped hot water storage device for power plants. Utility Model Content
