Abstract: Systems and apparatus for additive atomizing for severe operating environments are shown. An additive is introduced into a gas stream within a conduit, which provides atomization, into droplets, of the additive. The atomized droplets are then available for introduction into a severe operating environment, such as for example, a combustion chamber, furnace, incinerator, etc.

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.
