Beschreibung
Zusammenfassung:	A heat recovery steam generator includes a gas inlet for receiving a flow of exhaust gas from a gas turbine, a gas outlet opposite the gas inlet and configured to transport the flow of exhaust gas to atmosphere, and a sorbent injection device intermediate the gas inlet and the gas outlet, the sorbent injection device including at least one injection port configured to inject a sorbent into the flow of exhaust gas. The sorbent is configured to react with an acid gas within the flow of exhaust gas to neutralize the acid gas and inhibit the formation of salt deposits.
