Abstract

The corrosion of a sintered cordierite (2MgO·2Al2O3·5SiO2) ceramic by sodium sulphate (Na2SO4)—a common combustion condensate—was investigated at 1000°C. Laboratory tests with thin films of Na2SO4/O2 and Na2SO4/1% SO2−O2 were performed. In the Na2SO4/O2 case, the cordierite reacted to form NaAlSiO4. After several hours of corrosion, the Na2SO4 appeared to induced surface cracks in the cordierite. In the Na2SO4/1% SO2−O2 case, other dissolution reactions occurred. The material was also tested in a burner rig with No. 2 Diesel fuel and 2 p p m sodium. The corrosion process was similar to that observed in the Na2SO4/O2 furnace tests, with more severe attack occurring.
