该文从分析飞灰磨损的原因和位置出发，讨论了国内锅炉普遍采用的防磨罩、阻流板和防磨涂料等防磨措施。在此基础上，针对影响飞灰磨损的最主要因素──烟气速度，介绍了以冷态空气速度场测试技术为基础，应用计算流体力学结果进行分析的治理磨损的新方案。 Based on the analysis of the reason and position of the fly ash wear, this paper discusses the anti-wear measures commonly used in domestic boilers, such as anti-wear covers, spoilers and wear-resistant coatings. On the basis of this, aiming at the flue gas velocity, which is the most important factor affecting the wear of fly ash, a new scheme to treat wear and tear based on CFD test results is presented.
