Limestone is generally used as a desulfurizing agent material in circulating fluidized bed (CFB) boilers. In order to study in-situ desulfurization characteristics of domestic limestones in the operation condition of a oxy-fuel CFB, 4 different limestone samples were used to analyze the effect of CO2 on calcination and desulphurization behavior in a thermogravimetric analyzer (TGA, N-1000). The limestones used in these experiments is commercially used in domestic CFB boilers. Calcination and decalcination phenomena with different CO2 partial pressures were investigated at 850-900 ℃ conditions. Also, the effect of particle size on calcination and desulphurization was studied. |
