1、 Roots blower boiler fan
The boiler fan can be centrifugal or axial flow type according to the boiler specification. According to its function, it can be divided into boiler ventilator - conveying air to the boiler; Boiler induced draft fan - to remove flue gas from the boiler.
2、 Roots blower fan for ventilation
This type of fan is generally used for ventilation, heating and ventilation of factories and various buildings. The pressure is not high, but the noise is low. Centrifugal or axial flow fans can be used.
3、 Fans for Roots blower industrial furnaces (cupola, forge furnace, metallurgical furnace, etc.)
This kind of fan requires high pressure, which is generally 2940~14700n/㎡, that is, the range of high-pressure centrifugal fan. Due to the high pressure and large peripheral speed of the impeller, the impeller shall have sufficient strength during design.
4、 Roots blower mine fan
There are two kinds of them: one is the main fan (also called the main fan), which is used to deliver fresh air to the underground. Its flow rate is large, and the axial flow type is more suitable, and the centrifugal type is also useful; The other is local fan (also known as local fan), which is used for ventilation of mine working face. Its flow and pressure are small, and explosion-proof axial fan is mostly used.
5、 Roots blower pulverized coal fan
Centrifugal fans are mostly used to transport pulverized coal in the boiler combustion system of thermal power station. The pulverized coal fan can be divided into two types according to different purposes: one is the storage type pulverized coal fan, which blows the pulverized coal in the storage bin from its side to the furnace. The pulverized coal does not directly pass through the fan, so the exhaust pressure of the fan is required to be high; The other is a direct fired pulverized coal fan, which directly sends pulverized coal to the furnace. Wear resistant materials shall be used due to severe wear of pulverized coal on impeller and shell.
