Background
The heat storage is a key technology for solving the problems of fluctuation and instability of renewable energy sources, peak clipping and valley filling of the traditional power system and industrial waste heat recycling. The high-temperature steam is an important working medium for traditional power generation circulation and industrial waste heat utilization. For example, in solar thermal power generation, the solar thermal collector converts the collected solar radiation energy into superheated steam through the heat exchanger, and generates electric energy by using the traditional power cycle. However, due to a series of problems such as day-night discontinuity of solar energy and unstable energy caused by cloudy and rainy days, the stable output of the power of the solar photo-thermal power generation system is greatly influenced. It is therefore one of the effective methods to provide a steam thermal storage device in a solar thermal power generation system. If the industry has a large amount of high-temperature waste heat and waste heat, high-temperature steam is one of the main working media, but the intermittent characteristic of the high-temperature steam is difficult to directly utilize, so that the storage and the restabilization of the unstable industrial steam waste heat are key technologies for utilizing the industrial waste heat.

In order to further improve the efficiency of the system, the compression heat can be converted into high-temperature steam and the heat energy of the high-temperature steam can be stored, and the high-pressure air is transferred through the heat when electricity is generated, so that the inlet temperature of the expander is increased, and the efficiency of the system is improved. Therefore, design, development and experimental evaluation of the high-temperature vapor heat storage device are needed, but no high-power high-temperature vapor heat storage experimental system is available in the prior art. Therefore, a high-temperature steam heat storage experiment system is urgently needed to provide a necessary experiment platform for research, development and detection of a novel high-temperature steam heat storage device.
