As an efficient ventilation device, the boiler forced draught fan is mainly used in the ventilation and drafting of various steam boilers in thermal power plants. It can also be used for mine ventilation and general ventilation when there are no other special requirements. If the medium conveyed by the boiler forced ventilator is air, the maximum temperature required shall not exceed 80 °C. If the conveying medium is flue gas, the maximum temperature shall not exceed 250 °C.
Moreover, before the boiler forced draught fan, a dust removal device needs to be installed, which is mainly to reduce the dust content of the flue gas entering the fan to improve the service life of the fan. At present, there are many machines used in the metallurgical industry. The requirements of the metallurgical industry for wind turbine products are high temperature resistance. From mine to steel, it must go through the smelting process of ore sintering, iron making and steel making, that is, the whole process of steel smelting. All need a fan.
In addition, boiler forced draught fans are also required in the steel industry, cement industry and petrochemical industry. The application of fan products in the chemical industry is also divided into two categories. The ventilation and chemical industries for general ventilation and ventilation also focus on special-purpose fans, such as anti-corrosion fans and high-temperature fans.
