Effects of Temperature on the Desulphurization Characteristics of Wastes and Limestone

Effects of temperature on the desulphurization characteristics of wastes and limestone were studied by means of flue gas analyzer and the high temperature tube reactor. Desulphurization product characteristic was investigated respectively by XRD diffraction technology. The results show that sulfur capture ability of wastes higher than limestone's always at 800~900°C. White clay and carbide slag have better sulfur capture ability at 1000~1100°C. But sulfur capture abilities of salt slurry and red mud decrease at 1000~1100°C.
