Recently, the 10MW middle and high temperature heat storage experiment platform independently designed and developed by the team of the Energy Storage R & D Center of the Institute of Engineering Thermophysics, Chinese Academy of Sciences was commissioned at the Bijie Branch of the Institute and the National Energy Large-Scale Physical Energy Storage Technology (Bijie) R & D Center All performance parameters have reached or exceeded the design specifications. The medium and high temperature heat storage experimental platform is an important part of the large-scale physical energy storage technology experimental platform. The successful development of this platform will effectively promote the development and industrialization of new heat storage technology and large-scale compressed air energy storage technology.
Heat storage technology can solve the contradiction between the imbalance of heat energy supply and demand, and is an important means to effectively solve the social energy demand and achieve energy recycling. Based on the scientific research carried out on this platform, the characteristics of thermodynamics, heat transfer, and seepage / fluid mechanics of large-scale medium- and high-temperature heat storage units and systems under this operating parameter can be deeply understood. It is a new type of heat storage material in the field of heat storage. Expansion provides strong support.
The medium and high temperature heat storage experiment platform is mainly composed of cold and heat source preparation system, cold and heat source storage system, steam generation system, superheat system, measurement and control system and other parts. It can realize the experimental conditions of temperature range from normal temperature to 600 ℃, test power up to 10MW and test capacity of 10MWh. Using modern industrial automation control system, remote detection and control can be realized. Relying on the experimental platform, experimental research and performance testing under different temperature, pressure and flow conditions can be carried out for the heat storage unit and system, in order to break through the key scientific and technical bottlenecks of large-scale medium and high temperature heat storage devices and systems, and 10MW-100MW advanced The compressed air energy storage system, solar thermal power generation and industrial waste heat utilization provide key experimental platform support.
