火力抽水—蓄能发电是由汽轮机直接带动水泵抽水蓄能发电。文中分析了火力抽水—蓄能发电的发电效率、投资效益以及技术上的可行性。与传统的抽水蓄能发电相比 ,火力抽水—蓄能发电减少了 2次能量转换的损失和 1次电能传输的损失 ,总的发电效率可提高 1 0 %以上。其运行方式是全天 2 4 h抽水 ,电网峰负荷时发电。锅炉、汽轮机都可以满负荷工作 ,得到最高的热效率。用火力抽水—蓄能发电厂取代同样规模的火电厂和抽水蓄能电站 ,可以提高发电效率 ,降低供电煤耗率 ,增加发电量 ,降低设备投资。
Fire pumping-storage power generation is directly driven by a steam turbine to pump water storage and power generation. This paper analyzes the power generation efficiency, investment efficiency, and technical feasibility of firepower pumped-storage power generation. Compared with traditional pumped-storage power generation, firepower pumped-storage power generation reduces the loss of two energy conversions and the loss of one power transmission, and the total power generation efficiency can be increased by more than 10%. Its mode of operation is pumping water 24 hours a day, generating electricity when the grid peak loads. Boilers and steam turbines can work at full capacity and get the highest thermal efficiency. The use of firepower-storage-storage power plants to replace thermal power plants and pumped-storage power plants of the same size can improve power generation efficiency, reduce coal consumption rate of power supply, increase power generation, and reduce equipment investment.
