What is the water consumption rate of wet-cooled coal-fired power plants?

Units of different capacities are different in different regions and seasons, so there is no way to calculate the "rate". Let me give you a "quantitative" data, which is the data I used recently: a small steam turbine generator, 3 MW, evaporation and wind loss from the cooling tower: 18 .6 cubic meters/hour.

It is difficult to answer this question. Since the largest water consumption in power plants is circulating cooling water, this part of the water taken from the river is not consumed, but is discharged into the river. The other part of household firefighting water is no different from ordinary businesses. Then there is the desalinated water used in the boilers. This part of the water from power plants that do not provide heat is recycled and the amount replenished is very small. Make-up water from the cenThe heating cycle is linked to the steam supply volume and the condensate recovery rate. Therefore, power plants generally only count and evaluate water consumption related to production indicators, such as boiler feedwater flow, condensate recovery rate, etc. The statistics generally do not relate to the enormous quantities of circulating cooling water. Therefore, it has no practical meaning for power plants to calculate water consumption and water savings.
