[0002] Large boiler steam soot blower is a device for removing coke on the heating surface of boiler. The architecture of the short soot blower of boiler is composed of actuator, soot blower head and soot blower gun tube. When blowing, the head is extended into the furnace about 8 cm at an angle of 90°. Due to thermal stress, the head of the soot blower may be deflected after long-term operation. If the head of the soot blower is deflected, the blowing effect of the soot blower will be reduced or the heating surface will be damaged, resulting in over-temperature of the heating surface and even pipe explosion.

[0003] Therefore, when the unit is shut down, the multi-dimensional deformation of the main body space of the short soot blower head needs to be measured, and after the unit is overhauled, the distance between the nozzle center and the water wall is measured by manually extending the nozzle into the furnace to ensure that the distance meets the design specification. The angle between the nozzle and the inner tube and the water wall is perpendicular, so that the soot blower can clean the boiler heating surface, improve the heat transfer performance, adjust the steam temperature, improve the boiler efficiency and ensure the long-term safe and economic operation of the boiler.

[0004] Currently, since the main body space of the short soot blower head has multi-dimensional deformation, multiple detection tools need to be carried into the boiler when detecting the deformation, which has certain operation risk.
