Optimization of Thermal Discharge Scheme for the Phase II Project of Rizhao Power Plant

Rizhao sea area was characterized by a two-dimensional hydrodynamic model using the split steps finite method with triangle grids. The simulated tidal current field showed reasonable agreement. Heat transport and horizontal distribution of temperature in the sea water around Rizhao power plant was numerically simulated based on the tidal current field. The impact of different design schemes of thermal discharge from Rizhao power plant on water environment was predicted taking into account outfall location, water discharge and temperature rise. The optimal scheme is recommended according to the prediction results, i.e. the cooling seawater of both phase I and II projects discharges from the outfall PI. The recommendation is not only in accordance with Marine Functional Zoning of Rizhao but also economically reasonable.
