Abstract: As an important part of boiler thermal energy conversion, the operation status of equipment is directly related to the safety and stability of boiler operation. If the safety accident of pipe burst leakage occurs on the heating surface during operation, it will not only affect the economic benefits of the enterprise, but also threaten the personal safety of the operators, so it is very important to improve the operating environment of the equipment system. This paper first expounds the causes of the failure of the heating surface of the boiler in the thermal power plant, and then analyzes the prevention and control measures of the failure of the heating surface, so as to create favorable conditions for improving the safety and stability of the boiler operation in the thermal power plant.
Keywords: boiler; heating surface; failure causes; preventive measures
锅炉的运行效率直接关系到火电厂的经济效益,而锅炉运行的安全性和稳定性是其能够高效运行的基础保障,所以需要加强对锅炉设备运行环境的监督检查。受热面作为锅炉热能转换的重要组成部分,在其长期服役的过程中,受到各种因素的影响可能会出现受热面失效的现象,不利于锅炉的安全稳定运行。经过对锅炉受热面失效的原因进行总结分析,主要有超温、磨损、焊缝泄露、垢下腐蚀、热疲劳等,受热面失效会造成火电厂非计划停机,对企业的经济效益和安全生产造成不良影响。所以应该对锅炉受热面失效的原因进行充分的分析,然后从实际情况出发,制定出行之有效的防治措施,最大程度的避免受热面失效现象的发生,为火电厂的安全高效生产创造有利条件。
