Abstract: A new method, Once Through Conveyor (OTC) for cooling inland thermal power plants is proposed. It involves the diversion of water from an existing domestic supply network through the power plant condenser and back to the network. Since natural water sources are not being used, the problem of ecological disturbance, due to the increased temperature of the water, does not arise. Increased salinity in open reaches, due to greater evaporation caused by the higher temperature, is calculated to be insignificant, and no contamination by any toxic pollution is anticipated. This is well above the anticipated needs in the area by the year 2000. The OTC method is more energy efficient, cheaper, and less environmentally intrusive than other commonly used methods. This method may be highly suitable for the cooling of power plants built close to adequate water supply systems.
