摘要
提高软水的制作质量并定时排污，采用厚壁铜管的蒸发管束，且弯头处加焊防磨环，直管处焊翅片，另一方面，严格保持硫酸沸腾炉矿灰颜色为深棕色，从而延长低压废热锅炉蒸发管束的使用周期，使低压废热利用获得良好的经济效益。
The service life of a low pressure waste heat boiler for H2SO4 plant was prolonged by improving quality of feed water, regular blowdown, use of thick-wall finned tube bundle with wearing ring at elbows for vapourizer, and operating fluidized bed roaster under dark brown-cinder condition.
