Description

Technical Field

[0001] The utility model belongs to the technical field of hot water energy storage, in particular to a hot water energy storage device for a coal-fired thermal power plant. Background Art

[0002] The hot water energy storage device used in coal-fired thermal power plants is an important equipment that uses heat storage technology to achieve thermal and electrical decoupling and improve the peak-shaving capacity of coal-fired units. It mainly realizes its function by storing energy and releasing thermal energy.

[0003] Existing hot water energy storage devices for coal-fired thermal power plants usually discharge heat directly through pipes when releasing heat. This method will cause the heat energy in the energy storage device to be lost quickly. When a large amount of heat energy is not needed, the large amount of heat energy in the energy storage device will be lost, resulting in a waste of heat energy. In addition, a lot of time and energy will be required to re-store heat energy in the energy storage device. Therefore, we propose a hot water energy storage device for coal-fired thermal power plants. Utility Model Content
