A process is disclosed for inhibiting corrosion of metal surfaces and deposition of particulates in an air preheater system. In the process, a composition (preferably aqueous) comprising a corrosion inhibiting amine and a surfactant having an HLB value of from about 8 to about 20, preferably from about 10 to about 14, is supplied to the combustion gas-in side and/or to the air-in side of the air preheater for protection of the metal surfaces and minimizing such deposits. In a preferred embodiment, the process of the invention can employ an amine salt of a C12 to C24 tertiary alkyl amine an amine oxide, or an amine oxide salt, either alone or with a surfactant.

A process for inhibiting corrosion of metal surfaces and minimizing deposits in an air preheater system in which said metal surfaces are to be contacted with hot combustion gases and heat exchange is to be carried out between a cool air stream and said hot combustion gases comprising the step of supplying with the air to be preheated to the air-in side of said air preheater system a composition comprising a corrosion inhibiting amine or amine-substituted compound and a surfactant whereby said metal surfaces of said air preheater are thereby coated with said composition when they are contacted with said hot combustion gases.
