Higher working-fluid temperatures are required to boost efficiency, exposing subsystems to more corrosive environments. Issues of special concern to ceramists are corrosion and blinding of hot-gas particulate filters and catastrophic failure of high-temperature ceramic heat exchangers. Fuel and operational factors that affect the corrosion rates of structural ceramics in coal-fired combustor systems are described, with examples of the corrosion of silicon carbide-based materials. Attention is focused on hot-gas particulate filtration and heat exchangers; gasification systems are also discussed. Objective of the report is to help the experimentalist measuring these factors to better design tests.
