Sulfur trioxide formation/emissions in coalâfired airâ and oxyâfuel combustion processes: a review
In oxyâfuel combustion, fuel is burned using oxygen together with recycled flue gas, which is needed to control the combustion temperature. This leads to higher concentrations of sulfur dioxide and sulfur trioxide in the recycled gas, which can result in the formation of sulfuric acid and enhanced corrosion. Current experimental data on SO3 formation, reaction mechanisms, and mathematical modelling have indicated significant differences in SO3 formation between airâ and oxyâfuel combustion for both the wet and dry flue gas recycle options. This paper provides an extensive review of sulfur trioxide formation in airâ and oxyâfuel combustion environments, with an emphasis on coalâfired systems. The first part summarizes recent findings on oxyâfuel combustion experiments, as they affect sulfur trioxide formation. In the second part, the review focuses on sulfur trioxide formation mechanisms, and the influence of catalysis on sulfur trioxide formation. Finally, the current methods for measuring sulfur trioxide concentration are also reviewed along with the major difficulties associated with those measurements using data available from both benchâ and pilotâscale units
