评估了大型太阳能烟囱发电厂的性能特性。所研究的参考工厂具有玻璃覆盖的收集器和直径为160 m的1500 m高的烟囱。涡轮发电机位于烟囱的底部。在南非的一个特定地点，针对指定的气象数据，求解了适用于该工厂的吃水和相关能量方程。它表明，工厂的输出变化可测量在白天和电力也产生在夜间由于太阳能集热器下的地面的热容量。通过优化太阳能集热器的形状和高度，可以增加年发电量。
The performance characteristics of a large solar chimney power plant are evaluated. The reference plant studied, has a glass covered collector and a chimney that is 1500 m high with a diameter of 160 m. A turbogenerator is located at the base of the chimney. The draught and relevant energy equations applicable to the plant are solved for specified meteorological data at a particular site in South Africa. It is shown that the output of the plant changes measurably during the day and that power is also generated during the night due to the thermal capacity of the ground under the solar collector. By optimising the shape and height of the solar collector the annual power output can be increased.
