Coal-Fired Power Plant - an overview ScienceDirect Topics

1997-1-30  Andorra Coal-fired Power Plant (Teruel, Spain) produces annually over 1,000.000 tons of residual coal ashes. These ashes are composed approximately by 15 % of bottom ash and 85% of fly ash. They are mixed together with water and conducted through a pipe to the Valdeserrana Dam where the sluice is poured and the ashes settle.
