COAL PLANT WATER USAGEMOUNTAINTOP REMOVAL AND WATER"CLEAN COAL" AND INCREASED WATER USAGEENVIRONMENTAL IMPACTS FROM COAL PLANT WATER USAGEWATER CONSUMPTION BY STATESREPORTSRESOURCESWater is used by thermoelectric generating facilities (coal, natural gas, and nuclear) to make electricity through converting the water into high-pressure steam to drive turbines. Once through this cycle, the steam is cooled and condensed back into water, with some technologies using water to cool the steam, increasing a plant's water usage. In coal plants, water is also used to clean and process the fuel itself. The U.S. Geological Survey estimates that thermoelectric plants withdrew 195 bil...

How it Works: Water for Coal Union of Concerned Scientists

Coal-fired power plants, which produce almost half of the country’s electricity, have significant impacts on water quantity and quality in the United States. Water is used to extract, wash, and sometimes transport the coal; to cool the steam used to make electricity in the power plant; and to ...

2.1. Water Usage in Coal to Power Applications netl.doe.gov

So, in summary it can be said that gasification-based power offers efficiency benefits in the use of water. Raw water use in IGCC plants is lower than in pulverized coal plants. Without CCS, PC plants have a much higher steam turbine output, requiring more cooling water and condenser duties (typical raw water use ratio of 1.7:1.0).

Water and Energy - Withdrawal vs. Consumption

Other plant systems, including environmental controls, can also affect water consumption. For example, adding scrubbers on coal plants to reduce air emissions increases water consumption, as will carbon capture and storage technology. Hybrid systems to reduce water use are in different phases of research and development.

Cycle make up water consumption has to be converted in terms of percentage of MCR of feed water flow so that this methodology can be applied to other power plants. As it is not possible to reduce cycle make up water consumption to zero and minimum is the best, LSL (lower specification limit) cannot be fixed for water consumption.

The electricity can then be input to the electrical grid for use by society. Coal fired power plants follow the Rankine cycle in order to complete this process. Since they require plenty of water to be circulated in this cycle, coal power plants need to be located near a body of water. The process of coal fired plants can be seen below in Figure 3.
