Abstract: Oxy-fuel combustion technology, an effective greenhouse gas emission control technology, is an energy conservation and emission reduction technology with potential application. In this work the effects of flue gas components (SOx, NOx, H2O, Cl2/HCl etc.) on the formation of SO3 and Hg under oxy-fuel combustion condition, and the effects of fly ash on the adsorption and removal of SO3 and Hg enrichment in flue gas were systematically summarized and analysed. The feasible technical suggestions for synergistic control of SO3 and Hg under oxy-fuel combustion were put forward, which provides an important reference for the synergistic control of pollutants in the industrial application of oxy-fuel combustion. At the same time, the emission characteristics of SO3 and Hg under the current oxy-fuel combustion and the existing problems in the research direction of optimization control were analysed, and some suggestions for the future research direction were put forward.

Key words: oxygen-enriched combustion, sulfur trioxide, mercury, Emission characteristics, contaminant control
