[0002] A boiler is a device that converts the heat generated by fuel combustion into steam or hot water. Its main components include a furnace body, a burner, a heat exchanger, and a control system, and it is widely used in industrial production, building heating, power generation and other fields. At present, the commonly used fuels for boilers include coal, etc. After burning coal, coal cinder will be generated, and these coal cinders need to be discharged regularly. Therefore, a slag discharging pipe is arranged at the bottom of the boiler to facilitate the removal of furnace slag. However, there are some problems in the actual discharging process. For example, due to incomplete combustion of coal and large friction between coal cinders, the slag discharging pipe will be blocked, resulting in the situation that slag cannot be discharged. At this time, the staff needs to manually dredge the slag discharging pipe. During this process, not only is it easy to cause adverse effects such as scalding to the staff, but also the coal cinders will be directly discharged to the ground, resulting in the subsequent operation of secondary loading of the coal cinders on the ground, thus affecting the slag discharging efficiency.
