硫酸钙的还原分解特性

Reductive and Decompasible Characteristics of Calcium Sulfate

从热力学基本方程推导并预测钙基固硫剂的固硫产物—硫酸钙在其所处的还原性气氛中分解的可能,通过实验验证CaSO_4在还原性气氛中分解温度与理论推导温度的一致性。得出结论,在低温时,燃煤所处的还原性气氛是导致固硫率降低的主要因素。

To deduce and predict the possibility,outcome of fixed sulfur of calcium sulfate agent,decompose in reductive atmosphere based on fundamental function of thermodynamics,by experiment, test the temperature of decomposition of calcium suliate in the reductive atmosphere to be identical with the temperature of theoretical deduction. The conclusion is that fuel coal reductive atmosphere is main fact in which the rate of fixed sulfur will decrease at low temperature.
