摘要: Sulphur emission and the effect on ash properties boiler- tube corrosion in oxy-fuel combustion have received increasing attention recent years. Early investigation about calcium- based desulphurization oxy-fuel, addressed advantage to reduce SO2 emission. This paper, decomposition of calcium sulphate was characterized by thermogravimetric analyzer. The results showed that inhibited O2 concentration resulted from recycled flue gas. And CO2 had negative effect, which can be solved changing through appropriately adjusting gas ratio. kinetics mechanism sulfate-decomposition further analyzed. Compared with conventional atmosphere, reaction activation energy heightened conditions, difference increased rising temperature. So it confirm utilization rate under high temperature condition.
