| Abstract |
Coal thermal power plants traditionally require huge volumes of water to condense steam from the turbine exhaust. Coastal power plants may simply run a large amount of seawater through condensers in a single pass and discharge it back into the sea. However, marine organisms and submarine sediment could enter the cooling water intakes of such once-through systems. In this case study, CFD analysis for the impact of inflow of marine organisms and submarine sediment in a seawater intake system of a power plant was performed. The hydraulic model test method was followed. An objective numerical analysis model for practical impact evaluation was derived by selecting target marine organisms and sediments based on results of investigating surrounding marine environment. This technical paper investigated common challenges and solutions such as the protection of a seawater intake system from jellyfish, possibilities of a safe cooling water intake, coping with large sand quantities, and optimization of pump stations. |
