Abstract
A method and system for controlling one or more emissions includes introducing ammonia to react with at least a portion of sulfur trioxides in an exhaust emission and result in at least one or more ammoniated compounds. At least a portion of fly ash particles and the ammoniated compounds in the exhaust emission are precipitated. At least a portion of the ammonia from the precipitated ammoniated compounds is recovered with heat from the exhaust emission and the recovered ammonia is reused.
