High-ash coal preparation employs mainly “wet” methods with water flow rate of 5–10 t per 1 t of coal. Recycling water supply lowers “fresh” water demand but it is still required to pump considerable volumes of water slurries, which needs much power. On the other hand, dry preparation of low-grade coal using modern technologies is low efficient.

2019-12-4 In order to calculate the overall life-cycle water use of electricity generated from coal and natural gas, we estimated the water intensity of the processes that are upstream of the power plants, which include mining, drilling, transportation and processing of coal and natural gas.

2015-5-14 When considering water use in coal mining and processing, values range between 0.2-4.8 m 3 per tonne of coal: a 24-fold variation. Most probably the actual water use lies somewhere in between. Other estimations of water use along the coal chain

2014-4-30 In Scenario 4, coal-fired power generation is 5060 TWh in 2030, an increase of 83%, while total coal industry water use is reduced by 36% relative to 2008 actual levels. In general, since major water use reduction is most likely to occur in coal-fired power generation, we conclude that promoting strict policies and technical progress in the ...

2021-5-4 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). With carbon capture, the difference in water use is even more dramatic (2.5:1.0), as the chemical absorption process for ...

2016-10-22 Abstract. During cleaning of high-ash coal mainly “wet” processes are used which require 5 to 10 tons water consumption per 1 ton of coal. Arrangement of recycling water supply reduces demand in “fresh” water, but transportation of huge volumes of water slurry requires high energy consumption.
