Performance Study of Solar Chimney Power Plant System with a Sloped Collector

There is a solar chimney power plant system supported by southern sloped mountain for high latitudes. The sloped collector is built at suitable mountain hills, which also functions as a chimney. Then a short vertical chimney is added to install the vertical axis air turbine. Deduce and analysis the power and efficiency of the system. The result indicates that for northern latitude area near 35 degrees, the power and efficiency of the solar chimney power plant system with a appropriate sloped angle collector are higher than the solar chimney power plant system with a horizontal collector, besides, the system scale is bigger, the gap is more larger. Furthermore, the system can appropriately reduce the height of vertical chimney and construction problems.
