太阳能烟囱电站是一种很有前途的大规模太阳能热利用技术，寿命长。对中国西北地区的常规太阳能烟囱电站和斜坡式太阳能烟囱电站进行了经济性分析。现金流受到许多因素的影响，包括投资、回收期、通货膨胀率和太阳能发电的销售价格。并以兰州、中国为例，对CSCPP和SSCPP进行了技术经济分析。结果表明，SCPP的投资受其结构和材料价格的影响，在系统寿命周期内，SSCPP比CSCPP具有更高的性价比。此外，大容量的SCPP与传统的化石燃料燃烧厂相比具有很好的竞争力。考虑到西北地区充足的太阳辐射、优惠的政府政策、良好的生态环境等因素，对中国西北地区建设小型热电厂进行经济评价具有重要意义。
Solar chimney power plant (SCPP) with a long life span is a promising large-scale solar thermal utilization technology. This paper performs an economic analysis for the conventional solar chimney power plant (CSCPP) and the sloped solar chimney power plant (SSCPP) in Northwest China. Cash flows are influenced by many factors including the investment, the payback period, the inflation rate, and the sale price of solar electricity. The techno-economic analyses of the CSCPPs and SSCPPs are performed taking Lanzhou, China as a case study. The results show that the SCPP investment is influenced by both its configuration and the material price, and the SSCPP is more cost-effective than the CSCPP during the system life span. In addition, the SCPP with large power capacity holds good competitiveness with the conventional fossil fuel combustion plants. The economic evaluation of building SCPPs in Northwest China is of high significance considering the local abundant solar radiation, favorable government policy, an...
