Sustainability of geothermal power plant combined with thermodynamic and silica scaling model

摘要: Abstract This method of combining thermodynamic and silica scaling analysis aims to improve efficiency, power output sustainability in geothermal plants which suffer from high concentration silica. The proposed was employed an the Dieng plant. process starts with a performance evaluation existing plant system, is comprised many components where losses both energy exergy occur. Once has been evaluated, optimization operating parameters can be applied maximize its without expensive addition any new components. then continues development scenarios plant’s design, seeking potential methods performance. In these scenarios, expanded into double flash single flash-binary flash-binary. Silica behavior models are determine best scenario for development. It found that system expansion Geothermal Power Plant. produces 29,155 kW lowest excess deposit at 899 ppm. Although this lower than it less negative impact scaling. By introducing company obtain additional 4855 kW.
