沸腾炉炉体腐蚀损坏原因分析

摘要

After 2 years of operation in a company,the fluidized bed furnace has malfunctioned. The steel shell and the furnace roof had corroded and damaged seriously. Entrusted by the court, the quality identification team had conducted corrosion and damage reason analysis of the fluidized bed furnace body. The results show that the lining laying of furnace roof had quality defects and the painting process of steel shell did not conformed to the specifications of national standards and industrial standards. Those were the main reasons of corrosion and damage. After analysis,suggestions about lining laying and painting process of fluidized bed furnace were made.%某企业一座沸腾炉在投产2年后故障不断，炉体钢壳严重锈蚀，炉顶严重破损。受某法院委托，质量鉴定人员对沸腾炉炉体的腐蚀损坏原因进行鉴定。鉴定结果表明，沸腾炉炉顶耐火砖的砌筑存在质量缺陷，炉体钢壳的油漆工艺不符合国家和行业标准要求，造成沸腾炉炉体严重腐蚀损坏。最后对沸腾炉的炉顶砌筑和油漆工艺提出几点建议。
