Sea water can also be used to cool water in thermal power plants, but sea water cannot be used for boiler steam. Thermal power plants have a dedicated workshop to purify water quality, and they must be monitored regularly during operation to avoid exceeding the standard. Fresh water is replaced, regenerated, softened and desalinated to meet pure water quality requirements, then deoxygenated during operation, chemicals are added according to parameters to allow salts to solidify and precipitate. and are discharged through the sewer pipes to purify the water quality. You know that the teapot used for watering at home scales after prolonged use because the quality of the water is too hard and contains too much salt if you use a boiler with an evaporation capacity of several hundreds or thousands of tonsper hour. , the direct consequence will be the boiler. The pipes were blocked and the boiler was scrapped. If sea water is used as boiler water, the water treatment work will be more rigorous.
Nuclear power plants use seawater to cool the water, mainly because most nuclear power plants are built by the sea, so it is more convenient to use seawater
Of course, whether it is a nuclear power plant or a thermal power plant, when using seawater cooling water, you must pay attention to the anti-corrosion problems. There are many electrolytes in seawater with the ability to corrode. is much stronger than that of fresh water.
