Y8-39, Y9-38 series Induced draft fan for boiler

Product characteristics

Application: This fan is suitable for 0.5-35t/h industrial boiler with economizer and smoke and dust removal device. Where the intake conditions are similar. The performance and suitable can be selected, but the maximum intake temperature shall not exceed 250℃. Before the induced draft fan, it is necessary to install a dust removal device with a dust removal efficiency of not less than 85% to reduce the dust content of the flue gas entering the fan, which not only reduces the environmental pollution of the flue gas, but also reduces the wear and tear of the smoke on the fan, and helps to improve the service life of the fan.

Main features

※ The fan adopts single suction, the impeller adopts long and short phase forward curved blade, and the material is made of high strength ground steel. ※ The fan adopts belt drive or coupling drive.
※ The inlet and outlet of the fan are made into a collection type streamlined overall structure.
※ The transmission group is composed of spindle, bearing box, rolling bearing, pulley or coupling, etc. The spindle is made of high quality steel. Adopt rolling bearing, bearing box has integral and partial two forms. No4~ No6.3 adopts integral bearing box; No7.1-No16 adopts partial bearing box. Cooling water is required on both bearing boxes. Water consumption varies according to the working temperature and the ambient temperature, generally considered by 0.5~1ms/h. Thermometer and oil level indicator can be installed on the bearing box. The lubricating oil in the bearing box adopts L-AN46 total loss system oil, or adds the appropriate grade of oil or grease according to the requirements of the equipment label.
※ Fan standard supporting inlet and outlet soft connection, damping type spring composite shock damper.
