Abstract:
1. A method of increasing the value of coal burned in a coal burning facility, the method comprising: combusting coal containing mercury in the presence of at least one sorbent to produce heat energy, ash, and flue gases, said ash containing at least 90% by weight of the mercury originally present in the coal, said ash having a concentration of acid leachable mercury that is less than a concentration of acid leachable mercury in an ash produced by combusting the coal without the at least one sorbent; monitoring said flue gases for said mercury and adjusting the presence of the at least one sorbent to achieve a desired mercury emission to comply with an environmental regulation; and realizing a monetary savings by an avoidance of disposal costs of said fly ash produced.
