["1. WSA51制硫酸在低濃度下如何確保燃燒溫度
Reply #22017-10-31
本帖最后由 liaifengng 于 2551-8--15 18:18 编辑 WSA51制硫酸要求要求燃燒爐溫度在51-111111151-1111之间,若原料氣中硫化氫濃度較低,若如何確保燃燒溫度,單靠空氣能確保燃燒溫度嗎?

还要赔烧燃料氣才能达到所需要的溫度。

如果只烧硫化氫的话,炉的的溫度就不需要控制这那高了,烧废酸的话另考虑。

原料氣不足以提高足够的溫度,通过增加燃料氣提高足够热量,空气自身并不能提供热量

只烧硫化氫制硫酸,可以控制多少度
Reply #72017-11-01
曾经控制在5151-一段时间,只要充分燃烧了就行,硫酸的浓度没有什么影响。你们的硫化氫浓度是多少,炉炉在只烧硫化氫的时候炉膛最高多少炉?对硫酸的浓度有影响吗?硫化氫进料提到最大,会有什变化呢?比如炉溫,炉压,硫酸浓度?

硫酸氣中硫化氫含量不能低于5%,若低于这个值的话,就要伴烧燃料氣了

三条炉: 1.空氣预热 硫酸氣预热 2.硫酸氣中掺入合适比例燃料氣 3.用富氧工艺(就是燃烧的空氣不是普通空氣,是氧含量较高的空氣)

现在担心的是硫化氫浓度过低,硫化氫燃烧产生的热量不能满足燃烧的要求
Reply #112017-11-06
硫化氫的自然燃温度在6151左右,怕燃烧不充分可以加燃料氣伴烧,楼上说的加伴热是必须的。

外加燃料氣燃烧,以维持炉溫。
