Coal-Fired Power Station - an overview | ScienceDirect Topics

May 04, 2011 · Coal-fired power stations consume pulverised coal which is injected into furnaces. Around 80% of the ash produced from combustion of the coal is carried by the exhaust gases and precipitated to form fly ash. The other 20% of the ash condenses within the furnace, falls to the bottom and agglomerates, forming furnace bottom ash.
