A reagent drying system for use with a steam generation system [25] is described having a combustion chamber that produces exhaust flue gasses [FG2]. A preheater [150] receives the exhaust flue gasses [FG1] and transfers heat to create a heated input air stream [A2] and a diverted air stream [A2′]. The heated input air stream [A2] is provided to the combustion chamber. The diverted air stream [A2′] is provided to a dryer [196] as incremental air stream [IA]. Dryer [196] dries bulk reagents for dry milling into powder. The powder is then used to process the exhaust flue gasses to remove pollutants. The incremental air stream [IA] may also include leakage gasses [360] from preheater [150]. |
