OTEC is very sophisticated heat engine that uses the temperature difference between cooler deep and warmer surface seawaters to run a low-pressure turbine. Since the temperature difference is low, about 20°C, its thermal efficiency is also very low, about 3%.; In modern nuclear power plants the overall thermal efficiency is about one-third (33%), so
Get a QuoteAugust 13, 2019. A steam power plant uses water under pressure to operate. The water is present in pipes; it enters the boiler where the heat turns it into steam. This steam passes through the turbine, which rotates and in return the dynamo in the generator rotates and produces electricity.
