Abstract:Oxyfuel coal combustion, where coal is burned in oxygen instead of air, offers the potential for simplified CO2 sequestration, since the flue contains little N2 and is mainly CO2. However, the widespread use of flue gas recycling to dilute the pure oxygen feed stream exacerbates corrosion problems in the furnace and boiler tubes by increasing the concentrations of SO2, SO3, HCl, and H2O. In addition, the dew point temperature is raised, making condensation of H2O, H2SO4 and H2SO3more likely during downtime. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
