| 摘 要： | 当型煤中适当加入添加剂硅，铁组分燃烧生成新的Ｃａ－Ｆｅ－Ｓ－Ｓｉ－Ｏ体系后，固硫率明显提高，本文用Ｘ射线粉末衍射法与Ｘ射线荧光光谱法对该体系的高温固硫终产物进行产征，分析了灰渣样品并讨论添加剂对固硫率的影响，为型煤工业配料寻求可靠依据。

| Abstract: | The ash from burning a coal briquet with an additive(Si,Fe)for sulfur capture was characterized by using a X-ray powder diffraction method and a X-ray fluorescent spectrometry,giving the same chemical composition as that derived from the elemental analysis data.The results also indicated that CaSO4 was the major constituent of the ash;the content of sulfur in the ash was found to be 7.33% by weight;and the ash had a composition of Ca-FeS-Si-O showing a higher rate of sulfur capture. |
