摘要
运用X-650电子探针对加福煤飞灰颗粒进行了碳元素及其它元素的测定。研究表明:白球和棕色球的含碳量小于2％和3.5％,黑球含碳量约13％,黑块Ⅰ和黑块Ⅱ含碳量分别达61％和86％。黑块Ⅰ和黑块Ⅱ是飞灰含碳量高的根本原因。降低飞灰含碳量关键在于设法将黑块Ⅰ完全燃烧,使黑块Ⅱ尽可能着火燃烧。
This paper presents the results of electronic micro-probe measurement for carbon and other elements in particles of flying ash of Jiafu pulverized coal. The carbon content in white sphere is less then 2％, in brown sphere 3.2％, in black sphere about 13％, and in black lump Ⅰ and Ⅱ up to 61％ and 81％, respectively. The presence of the black lump Ⅰ and Ⅱ dictates the high carbon content of the flying ash. In order to decrease the carbon content, it is important to burn out black lump Ⅰ and ignite black lump Ⅱ as much as possible.
