Analysis of Calcium Sulfate Decomposition by Thermodynamics under O2/CO2 Atmosphere
Coal combustion under O2/CO2 atmosphere show advantages in calcium-based desulfurization. In view of this burning atmosphere condition, from the reverse reaction of sulfuration process analysising characteristics of calcium sulfate decomposition by thermodynamics, draw the conclusion that: under this flue gas environment, the calcium sulfate decomposition temperature enhanced, which reduce the capability of calcium sulfate decomposition. Simultaneously comparing change tendency of controlling characteristics in sulfation processes under O2/CO2 atmosphere with traditional sulfation processes by dynamics, further draw that product resistance was relatively gradually weaken and make gases transport more smoothly, which improve desulphurization efficiency.
