The FAN47-Y centrifugal boiler induced draft fan (hereinafter referred to as the fan) is a specially designed centrifugal ventilation fan for single suction high-temperature boilers (kilns) with advanced technology independently developed by our company. The fan has superior performance, compact structure, and easy installation and maintenance, and can be widely used for the supply and induced draft of boilers (kilns) in industrial and mining enterprises.

Airflow range: 1323-69347m ³/h

Full pressure range: 716-3874pa

The fan transmission system is structurally equipped with C-type and D-type structures;

The fan specifications range from 315 to 12.4 #, with a total of 11 machine numbers;

FAN47-Y boiler induced draft fan is used in industrial boilers with a capacity of 0.2-20t/h that burn various media and are equipped with smoke and dust removal devices. Any boiler with equivalent inlet conditions and suitable performance can be used, but the maximum temperature shall not exceed 250 ℃.

The parameters of this fan have been converted based on a temperature of 250 degrees. If there are other different operating conditions, please convert according to the state formula specified on page five.

Fan structure:

Impeller group:

The impeller consists of 12 backward inclined flat blades made of Q345 (16Mn) material, welded between the conical wheel cover and the flat disc, and subjected to dynamic balance correction. Therefore, it has a balanced operation, high strength and wear resistance, and a long service life.

Chassis group:

The casing is a logarithmic spiral structure, welded from high-quality steel plates. The surface of the product is treated with acid pickling, phosphating or shot blasting, and then coated with plastic powder or paint.

The motor or bearing box bracket structure of each transmission mode of the fan has been optimized and designed, welded together with the casing, with a beautiful appearance, easy disassembly, and sturdy structure.

From 1600 to 2000, the upper and lower Haff structures are made along the split surface. When installation and transportation are restricted, it must be specified when ordering. The casing can be made into a structure that meets special requirements.

Fan collector department:

It has a nozzle shaped curve, which is formed by integral spinning and integrated with the inlet ring, making it convenient for users to connect pipelines.

Transmission group:

The transmission part adopts a CNC precision machine tool for integral boring and cutting manufacturing of the bearing box, which is composed of bearings, spindle, V-belt (coupling) transmission system, etc. Optional domestic/imported bearings and oil (grease) lubrication are available. The spindle is made of 45 # high-quality carbon steel that has been precision machined after quenching and tempering, and has sufficient safety and fatigue resistance in design.

The fan is equipped with high-quality European standard cone sleeve belt wheels, which are easy to repair and maintain (the triangle belt can be optionally equipped with imported brand tape such as Samsung according to the requirements).

Base group:

The series chassis is welded with steel sections and equipped with spring or rubber shock absorbers for seismic isolation design. The external structure is solid, compact and reliable.
