基于底吹炉余热锅炉漏水和堵塞问题的改进研究

Improvement Research on Water Leakage and Blocking Problems of Waste Heat Boiler Based on Bottom Blowing Furnace

垣曲冶炼厂富氧底吹炉余热锅炉生产中存在爆管漏水、对流管束频繁堵塞等问题,严重制约生产连续性。本文对于锅炉漏水问题从高温腐蚀和烟尘冲刷两方面开展研究并改进;针对锅炉堵塞的问题,从工艺指标控制和设备升级等方面进行优化解决。措施实施后,余热锅炉实现安全平稳运行。

In the production of waste heat boilers for oxygen rich bottom blowing furnaces in our factory,there are problems such as pipe bursts,water leakage,and frequent blockage of convection tube bundles,which seriously restrict production continuity.Conduct research and improvement on the issue of boiler water leakage from two aspects:high-temperature corrosion and smoke erosion;Optimize and solve the problem of boiler blockage from aspects such as process index control and equipment upgrade.After the implementation of the measures,the waste heat boiler achieved safe and stable operation.
