ABSTRACT:
A method of removing mercury or mercury-containing material from flue gas produced by a coal-burning main furnace includes feeding coal, which contains mercury or mercury-containing material, to a main furnace which produces flue gas. The method further includes feeding the coal to an auxiliary burner which produces a slipstream of flyash, feeding the slipstream of flyash from the auxiliary burner into the flue gas produced by the main furnace, and introducing a mercury-active oxidant to the coal being fed to the auxiliary burner, the combustion air fed to the auxiliary burner, and/or the flyash.
