[0002] Steam soot blowing is a method of using high-temperature and high-pressure steam to remove dust on the surfaces of boilers and other equipment. The following is a detailed explanation of steam soot blowing: I. Working principle of steam soot blowing The steam soot blower works through the following steps: The water pump lifts water from the water storage tank to the inlet of the heater in the boiler. In the heater, the water is heated and converted into steam. The steam enters the soot blower through the pipeline and is ejected from the nozzle of the soot blower at high speed. When the steam is ejected from the nozzle, it forms a high-speed jet, hitting the dust and dirt in the boiler. The dust and dirt are removed by the impact force and the heat of the steam. The removed dust and dirt are discharged from the boiler through the ash discharge pipeline. II. Application of steam soot blowing Steam soot blowers are widely used in the fields of petrochemical industry, electric power, steel, building materials, and food. In the electric power industry, steam soot blowers are often used to clean equipment such as boilers, heating furnaces, heat exchangers, and condensers to ensure the normal operation and production efficiency of the equipment. III. Advantages of steam soot blowing It can be arranged at various parts in the boiler to directly blow soot on the heating surfaces of the furnace, horizontal flue, and tail shaft.
