Abstract
A heat recovery steam generator (HRSG) () including: an economizer () configured to heat a working fluid by extracting heat from a flow of flue gas (). The HRSG includes a diluting fluid injector arrangement () configured to inject a diluting fluid () effective to dilute a concentration of a gaseous corrosive when compared to an undiluted concentration of the gaseous corrosive in the flow of flue gas. The HRSG also includes a preheater () configured to preheat the diluting fluid prior to injection.
