Abstract

Carbon capture and storage (CCS) is shown to be one of the key technologies for CO2 emissions reduction in numerous energy scenario analyses. In addition to moving towards emission free energy production, improved energy efficiency is essential in order to reach emission reduction targets. Oxyfuel combustion can be expected to differ from combustion in air by e.g. modified distribution of fireside temperatures, much reduced NOx but increased levels of fireside CO2, SO2 and water levels due to extensive flue gas recirculation. Increased flue gas recirculation may increase the concentration of a number of contaminants in the deposited ash and promote fouling and corrosion. In the paper, the oxidation performance of superheater steels has been determined at 580 and 650ºC under simulated oxyfuel firing conditions. The results are compared to corresponding results from simulated air-fired coal combustion conditions.
