摘要
随着中国"3060"双碳战略的推进,确保煤粉稳定点火和燃烧对于煤电行业由基础负荷电源向调节型电源转型至关重要.而其中一个核心问题是如何有效地监测和控制水冷壁的温度.针对燃煤质量多变、机组频繁调峰以及超临界汽水特性等复杂性带来的挑战,文章通过在锅炉水冷壁纵横布置大量温度测点,构建全面的多点测温系统,以直观地监测水冷壁的温度变化.该方法不仅能提供关于水冷壁整体温度的详尽数据,还能有效支持锅炉燃烧过程的控制和调节,从而提高电站锅炉的安全性和经济性.通过广泛、多点的温度监测,可以实时监测和记录水冷壁的温度变化,及时发现并解决水冷壁横向裂纹、高温腐蚀等问题,为优化锅炉运行参数提供依据.
Abstract
With the promotion of Chinese"3060"dual carbon strategy,ensuring stable ignition and combustion of coal powder is crucial for the transformation of the coal-fired power industry from basic load power sources to regulated power sources.One of the core issues is how to effectively monitor and control the temperature of the water-cooled wall.In response to the challenges posed by the complexity of variable coal quality,frequent peak shaving of units,and supercritical steam water characteristics,this paper constructs a comprehensive multi-point temperature measurement system by arranging a large number of temperature measurement points vertically and horizontally on the boiler water-cooled wall to intuitively monitor the temperature changes of the water-cooled wall.This method not only provides detailed data on the overall temperature of the water-cooled wall,but also effectively supports the control and regulation of the boiler combustion process,thereby improving the safety and economy of power plant boilers.Through extensive and multi-point temperature monitoring,real-time monitoring and recording of temperature changes in the water-cooled wall can be achieved,and problems such as transverse cracks and high-temperature corrosion of the water-cooled wall can be detected and solved in a timely manner,providing a basis for optimizing boiler operating parameters.
