焦炉烟气酸露点计算方法比较与分析
|
摘要
针对焦炉烟气脱硫脱硝后排放温度可能低于酸露点的情况,对比分析了酸露点温度常用的计算公式,得到不同工况的最低酸露点温度,以避免低温腐蚀现象,具有一定的指导意义。
The temperature of chimney emission after desulfurization and denitrification may drop below the acid dew point.In this paper, the commonly-used calculation formula and empirical formula of acid dew point are compared and analyzed.It will find the suitable temperature of coke oven chimney emissions under different conditions to avoid low temperature corrosion, which plays a role of guiding significance in cokemaking.
