FORMATION OF ALKALI IRON SULFATES AND OTHER COMPOUNDS CAUSING CORROSION IN BOILERS AND GAS TURBINES

Abstract

Experiments using radioactive sulfur revealed the much greater reactivity of SO3, relative to SO2, with surfaces such as are present in a combustion gas stream. Detailed examinations were made of numerous deposits removed from boilers and gas turbines to identify the compounds present. Work was done to determine if an electrochemical cell could be used as a rapid indication of corrosive conditions; it was concluded that this would require more time to develop than could be justified for this project. Further experiments were made in a small oil-burning furnace to investigate reactions between flue gas constituents and compounds found in deposits associated with corrosive conditions.
