转化炉烟道空气预热器中结晶体的研究

RESEARCH ON CRYSTAL FORMED IN FLUE AIR PREHEATER OF CONVERTER

对转化炉烟道空气预热器中析出的浅绿色物质进行定性、定量分析,其中阳离子有Fe^(2+)、Ni^(2+)、Cu^(2+)等,阴离子有NO_3^-和SO_4^(2-)。根据晶体成分,分析其成因及危害,并提出控制措施。

A qualitative and quantitative analysis was made for the light green material,which was formed in the air preheater of converter. The main components of the crystal were Fe2＋, Ni2＋, Cu2＋, etc., anions were NO3-and SO42-. The cause of formation and hazard of the crystal were analyzed, and control measures were put forward.
