摘　　要：针对燃煤电厂锅炉受热面超温现象,开展预防与监测管壁超温的水动力特性研究。通过研究发现热力计算不精确、燃烧器选型不当、受热面布置不合理、调温条件不充分等,因热偏差氧化最终导致锅炉受热面超温。通过水动力计算研究,建立壁温分布模型,揭示受热面超温爆管的根本原因,为分析壁温变化、开发测量壁温方法提供详细的理论基础。A study is conducted on the dynamic characteristics of tube wall superheated water in response to the phenomenon of overheating on the heating surface of coal-fired power plant boilers.Through research,it has been found that inaccurate thermal calculations,improper selection of burners,unreasonable arrangement of heating surfaces,and insufficient temperature control conditions ultimately lead to overheating of the boiler heating surface due to thermal deviation oxidation.Through hydrodynamic calculations,a wall temperature distribution model is established to reveal the fundamental cause of overheating and tube bursting on the heating surface,providing a detailed theoretical basis for analyzing wall temperature changes and developing measurement methods.
