Performance Enhancement of Solar Chimney Power Plant from Geothermal Power Plant Waste Heat

Abstract

A Solar Chimney Power Plant (Scpp) Sometimes Also Called "Solar Chimney" Or Just "Solar Tower" Is A Renewable Energy Power Plant That Transforms Solar Energy Into Electricity. The Scpp Consists Of Three Essential Elements; Solar Collector Roof, Chimney Tower, And Wind Turbine(S). Several Technologies Exist That Can Convert Solar Energy Into Electrical Energy. The Solar Chimney Is Part Of The Solar Thermal Groups Of Solar Conversion Technologies. However, Due To Its Greater Scale And Simplicity, The Solar Chimney May Have An Economic Efficiency Approaching Or Exceeding That Of The Other Methods, But It Has Low Efficiency Of Less Than 2%. In Addition Solar Chimney Power Plant (Scpp) Dominated By The Solar Radiation, Its Discontinuous Operation Is An Unavoidable Problem. Solar Chimney Efficiency And Power Output Have Mainly Determined By The Efficiency Of Solar Collector Roof. In This Thesis, The Transient Thermal And Hydrodynamic Behavior Of Working Fluid Of Solar Chimney Power Plant Using Waste Water Were Investigated To Characterize The Performance Of Solar Chimney By Numerical And Theoretical Method. Numerical Solution Technique Used To Solve A Differential Equation Form Of Governing Equations Using Finite Difference Discretization Scheme. The Result Shows, The Collector Temperature Increases By 7 ??C, The Pressure Potential Is Found 182.82 Pa, The Pressure Drop On The Turbine Was 121.88 Pa, And The Pressure Loss Was 60.94 Pa And The Power Output 123.59 Kw. As A Result, The Collector Efficiency Increases From 32% To 43.58% And The Overall Efficiency Of Plant Increases From 0.176% To 0.242% From The Result, It Can Conclude That The Efficiency Of Solar Chimney Power Plant Is Improved And The Power Fluctuation Can Be Controlled By Using Geothermal Wastewater Heat.
