锅炉炉底承压管海水腐蚀爆管的原因与防治

Analysis and Prevention of Furnace Floor Pressure Pipe Rupture Resulted from Seawater Corrosion

针对湛江发电厂锅炉水封槽顶部水冷壁管及底部加热管腐蚀较严重,多次出现腐蚀爆管停炉,介绍出现海水腐蚀的环境,并对形成机理进行详细分析,就锅炉防海水腐蚀对策进行探讨。

serious corrosbn occurred on the water wall tubes on the water seal tank top and floor heationg tubes,and corrosion,tube rupture and shutdown phenomena occurred many times.this paper briefs the seawater corrosion environment,analyzes the forming mechanism in detail and approaches the counter measures for preventing seawater corrosion of boiler.
