摘要: Because SO3 participates in both high- and low-temperature corrosion processes, there is a general concern about the formation under oxy-fuel fired conditions. This work has aim to evaluate influence of combustion parameters on SO3. Experiments were conducted air-fired experiments with propane as fuel injection SO2 oxidizer. The concentration was measured controlled condensation method at furnace outlet well flame. show that gas-phase an important contributor strong during burnout fuel. In wet flue-gas recycle (FGR), more formed than dry FGR similar temperature conditions, which indicates H2O enhances formation. also rises increase temperature. residence time increases reduced ratio, ratio directly influences combustion. obvious experiments, rose ratio.
