The primary air fan is a key piece of equipment used to provide primary air in a boiler system. Its main function is to feed air into the combustion chamber or pulverized coal combustion system of the boiler to ensure that the fuel can get enough oxygen for preliminary combustion. In a coal-fired boiler, the primary fan not only provides air for combustion, but is also responsible for mixing the pulverized coal with air and transporting it to the furnace chamber, so that the pulverized coal can be quickly mixed with air and burned.
The primary air fan pushes the air flow by mechanical force and is usually connected to a coal mill, which mixes the air with the pulverized coal and sends it to the boiler combustion chamber through the conveying pipeline. It plays a vital role in the early stages of the combustion process, ensuring that the fuel is fully ignited and begins to burn efficiently. The air volume and speed of the primary air fan can be adjusted to control the combustion intensity and efficiency of the boiler.
Primary air fans are used in conjunction with secondary air fans, which provide additional air to ensure further oxidation of the fuel during the combustion process, reducing waste and emissions from inadequate combustion.
Primary air fans are widely used in coal-fired power plants, industrial boilers, and chemical and metallurgical industries. It is vital to improve combustion efficiency, reduce pollutant emissions and ensure the stable operation of the boiler.
