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.
