摘　　要：介绍了立式集热板式太阳能热气流发电系统的结构及原理,分析了系统的最大输出功率及最大能量转换率。分析得出,当发电系统中烟囱的高度、宽度及太阳辐射强度增加时,均可使系统的最大输出功率和最大能量转换率增加,其中烟囱高度的影响最为显著,同时环境温度对系统功率也有一定影响。另外,系统规模受高层建筑规模的限制,最大能量转换率比原始结构的太阳能热气流电站小,但可为城市建筑节能提供新思路。The structure and principle of hot -air- flow power generation system with vertical heat collector have been presented,the maximum output power and the energy coversion efficiency of the said system being analysed. Through analysis, the conclusion obtained is as follows： the maximum output power and the maximum energy conversion efficiency of the said system increase as the chimey height, width,and the solar radiation increase, and the impact of chimney height is most significant. At the same time, the ambient temperature has also certain effect upon the system output power. Furthermore,the maximum energy conversion efficiency of the said power generation system is smaller than that of the original structure of powre plant due to the size of said system is limited by the high buildings,but the new kind of solar energy power generation system can provide new train of thought for the energy - saving in urban buildings.
