An industrial boiler fan is a key piece of equipment used in industrial boiler systems to support the combustion process in the boiler by providing a strong flow of air. The main function of an industrial boiler fan is to deliver air or exhaust gases inside the boiler to ensure that the fuel is adequately combusted in the boiler, thereby increasing the efficiency and output of the boiler. When the fan is in operation, it creates a strong airflow through mechanical rotation that helps the boiler maintain the air supply or exhaust gas discharge required for combustion.

Based on their use, industrial boiler fans can be categorized into several types, commonly including:
1. Blower: the main function of blowers is to provide fresh air to the combustion chamber of the boiler to ensure that the fuel can be fully combusted
2. Induced draft fan: the role of the induced draft fan is to extract the combustion exhaust gas from the boiler and discharge it out of the boiler system through the smoke exhaust system, to maintain a proper negative pressure in the furnace chamber and ensure that the combustion exhaust gas does not flow backward.
3. Primary Air Fan: The function of the fans is to provide the initial air supply for the pulverized coal combustion to ensure that the pulverized coal fuel can be quickly mixed with the air and burned after it enters the furnace chamber.
4. Exhaust fan/smoke exhaust fan: The function of exhaust fan or smoke exhaust fan is to exhaust the smoke and exhaust gases produced during fuel combustion out of the boiler and the site, and to maintain air circulation and air pressure balance in the boiler.
Application areas of industrial boiler fans:
1. Electric power industry: in coal-fired power plants and gas-fired power plants, it is used for boiler combustion and exhaust gas discharge.
2. Chemical industry: used in steam boiler system of chemical plants to ensure efficient combustion of fuel.
3. Metallurgical industry: in steel, aluminum and other metallurgical industries, used in industrial furnace combustion air supply and smoke exhaust system.
4. Textile, paper and other light industries: in the boiler systems of these industries, fans are used to provide the steam needed for heating.
