This standard specifies the basic design requirements, testing and acceptance, complete set supply and guarantee, marking, packaging and transportation of centrifugal induced draft fans for industrial steam boilers. This standard applies to centrifugal induced draft fans for industrial steam boilers with a production capacity of 1 to 20t/h. The inlet of the induced draft fan should be equipped with a dust removal device. The inlet flue gas temperature of the induced draft fan should be greater than 165°C and less than 250°C, and the dust content of the flue gas should not be greater than 400mmg/m^(3). This standard does not apply to boiler induced draft fans used in power stations.
