光热发电空冷系统选择与优化配置

Air Cooling System Choosing and Optimized Configuration for Solar Thermal Power Generation

指出了不同的空冷系统(直冷、间冷等)对光热发电的影响均不一样,需要对比选择,从中选择适宜光热发电的空冷系统,供工程应用参考。空冷系统的运行背压直接影响着光热系统的发电量,通过对直接空冷系统不同运行背压的优化和比较,得到一个最佳经济点,即以最合理的空冷系统运行背压,来获得光热机组最大的发电量。

Different air cooling systems（direct cooling and indirect effect） have different effects on solar thermal power generation,thus, it needs to compare and choose the most proper air cooling system for solar thermal power generation. The operation pressure of the air cooling system directly affects the power output of solar thermal system. Through the optimization and comparison of different operating back pressures of the direct air-cooling system, an optimal economic point is obtained, ie, the maximum power output of the solar thermal unit is obtained by operating the air-cooling system under the most proper back pressure.
