Task 2: Economizer Corrosion Rates This study was aimed at quantifying corrosion potential in marine boiler economizers with regard to acid dewpoint. The test plan called for operation of one probe below the acid dewpoint for the flue gas of the tested boiler, while the second probe was operated at about 100°F (55°C) above the acid dewpoint

condensing boilers, which are designed in order to avoid flue gas condensation and thus low temperature corrosion. Non-condensing boilers exit flue gas temperature is typically between 150°C and 180°C, which leads to up to 10% of sensible heat loss. Condensing technology consists of cooling the exhaust stream below the dew
