1 Overview
1.1 Product features
4-73 series centrifugal fans (hereinafter referred to as ventilators) are suitable for ventilation and induced draft fan systems of 2-670T/h steam boilers in thermal power plants. It can also be used for mine ventilation and general ventilation when there are no other special requirements; it is mainly used to meet applications that require large air flow, with low noise and high efficiency. According to user needs, we can make ventilators that are resistant to high temperature, corrosion, wear and other harsh working conditions.
The implementation standard of this ventilator is: GB/T 3235-2008 "Technical Conditions for General Purpose Centrifugal Ventilators".
1.2 Main uses and scope of application
The ventilator can transport clean gas, dusty gas, combustible gas, corrosive gas, powder or granular materials at normal or high temperature.
Typical applications include: building ventilation, mine ventilation, smoke exhaust, drying, clinker cooling, gas transportation, light material transportation, blast and induced draft in industrial boiler systems, air supply in kiln systems/incinerator systems And induced draft, air purification equipment, industrial dust collector system, etc., in addition to the industrial field, it is also often used in the agricultural and civil fields. It is one of the most widely used fan systems.
