| 摘 要： | 通过对2种不同结构、不同烧成气氛的梭式窑的整个烧成过程中NOx生成进行测试分析,得出快速升温将增加整个陶瓷烧成过程中NOx的生成;其次,烧嘴的合理布置,改善窑体结构,加强高温阶段窑内温度场的均匀性,可以减少NOx的生成;第三,还原气氛可抑制NOx的生成;最后,提出降低陶瓷烧成中NOx生成的几点建议.

| Abstract: | Three conclusions can be drawn in this paper, after testing and analyzing NO_x formation during the whole time of ceramics sintered in two shuttle kilns of various structures and sintered atmosphere. To begin with, quick rise in temperature results in increasing NO_x formation during the whole time of ceramics sintered. Secondly, it is a better way to drop NO_x formation that temperature uniformity is improved by reasonably arranging burners in shuttle kiln and improving the kiln structure. In addition, deoxidation atmosphere can restrain NO_x formation. Finally,some suggestions are brought forward for decreasing NO_x formation during ceramics sintering. |
