This paper explores the characteristics of CaO co-carbonation and sulfidation under CFB oxygen-enriched combustion, and studies the change of the conversion rate of CaO co-carbonation and sulfidation under different oxygen-enriched concentrations by experimental methods. It also analyzes the influence of oil and gas combustion and coal combustion on the co-carbonation and sulfidation characteristics of CaO, and finally draws the conclusion that the conversion rate of CaO co-carbonation and sulfidation under CFB oxygen-enriched combustion increases with the increase of oxygen-enriched concentration, and the influence of oil and gas combustion on CaO co-carbonation and sulfidation conversion rate is small, while coal combustion will reduce the conversion rate of CaO co-carbonation and sulfidation.【Keywords】CFB; Oxygen-enriched combustion; CaO; Carbonation; Sulfidation
