Energy storage system based on thermochemical energy storage and Rankine cycle and operation method
The invention relates to the technical field of energy storage, in particular to an energy storage system based on thermochemical energy storage and Rankine cycle and an operation method. The energy storage system comprises a storage device, an energy storage device, an energy release device and a power generation device. The energy storage equipment comprises a calcium carbonate rotary calcining kiln, a first heat exchanger network and an electric heater which are sequentially connected. Excessive electric power is converted into heat energy through an electric heater, and the heat energy is converted into chemical energy stored in calcium oxide through calcium carbonate decomposition reaction in the calcium carbonate rotary calcining kiln; chemical energy stored in calcium oxide is converted into heat energy through the energy release equipment, and then the heat energy is converted into electric energy through the power generation equipment, so that the power utilization requirement of a terminal user is met. According to the energy storage system provided by the invention, conversion, transmission and storage among different energies can be realized, the energy conversion efficiency is high, the coal consumption in the energy conversion process can be effectively reduced, and the requirements of energy conservation, carbon reduction and flexible transformation of a coal-fired power plant are met.
本发明涉及能量储存技术领域，涉及一种基于热化学储能与朗肯循环的储能系统及运行方法。储能系统包括存储设备、储能设备、释能设备和发电设备。储能设备包括碳酸钙回转式煅烧窑、第一换热器网络和电加热器，各结构组件依次连接。通过电加热器将过剩电力转化成热能，通过在碳酸钙回转式煅烧窑内发生碳酸钙分解反应，实现将热能转换为储存于氧化钙内的化学能；通过释能设备将存储于氧化钙内的化学能转化为热能，再经发电设备将热能转化为电能，满足终端用户的用电需求。本发明提供的储能系统能够实现不同能量之间的转化、传递和存储，能量转化效率高，并且能够有效减少能量转化过程中的煤耗量，满足燃煤电厂的节能降碳和灵活性改造需求。
