Dry Storage (landfills) At landfill sites, dry coal ash can be dispersed by wind and blown into neighboring plots of land as "fugitive dust;" this carcinogenladen dust can be a major health concern when inhaled, affecting the lungs and bronchia. Landfills are also dangerous to ground water, especially when they are not properly lined.

rising hot gases. In the flash dryer, coal is fed into a stream of hot gases for instantaneous drying. The dried coal and wet gases are both drawn up a drying column and into a cyclone for separation. In the multilouvered dryer, hot gases are passed through a falling curtain of coal, which is then raised by flights of a specially designed conveyor.
