沸腾炉烟尘磨损性及对策

Abrasiveness of Fluidized Bed Boiler Soot and Wearproof Measures

沸腾炉烟尘含尘浓度高达 2 0 0～ 30 0 g/m3,并且温度高 ,成分杂 ,其对净化系统的磨损性不容忽视。本文通过探讨高浓度沸腾炉烟尘的磨损机制 ,针对湘南某化工厂运行实践 ,提出了切实可行的防磨损系列措施。

Soot system of fluidized bed boiler has high density by 200~300g/nm3, high humidity and mixed components, so the abrasiveness to the decontamination system cannot be ignored. The paper analyzed the abrasiveness mechanism of high-density soot in fluidized bed boiler and discussed the practicable wearproof measures in allusion to the operational practice for a given chemical factory in south Hunan.
