Large quantities of water are often needed to remove impurities from coal in the process is known as coal washing for instance in china around onefifth of the water used in the coal industry is used for this process this process helps reduce air pollution as it eliminates around 50 of the ash content in the coal
Coal preparation plant process and equipment for coal washing coal washing is an indispensable process for deep processing of coal coal preparation plant also named coal wash plant the coal directly mined from the mine is called raw coal
Whats more with the trend of improving coal product quality and coal washing efficiency many coal washing plants chose to replace jigging by hmcheavy medium cyclone however although the separation effect of heavy dense medium is better than jigging the coal washing process is relatively complex with high cost

Coal washing plant the enrichment process is made by taking advantage of the density difference which is the physical properties of the coal raw coal material which is fed into heavy medium sinks while the shale refuses float and these products are taken separately and the enrichment process
When fuel switching or coal cleaning is not an option flue gas desulfurization fgd is selected to control sulfur dioxide emissions from coalfired power plants except for fluidizedbed combustion systems which is discussed later in this chapter fgd has been in commercial practice since the early 1970s it has become the most widely used technique to control sulfur dioxide emissions next
