Additive atomizing systems and apparatus

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.
