Y10-21 Industrial Boiler Induced Draft Fan is designed for flue-gas extraction in industrial boiler systems.
The series covers No.8 and No.9 configurations with reference airflow of 4,215–16,252 m³/h, total pressure of 2,303–3,312 Pa and motor power of 7.5–22 kW.
C-type belt drive and D-type coupling drive arrangements are available. Final selection should consider airflow, pressure, flue-gas temperature, dust condition, outlet direction, voltage and frequency.
Y10-21 is a single-inlet centrifugal induced draft fan developed for industrial boiler flue-gas extraction. No.8 and No.9 configurations cover reference duties for 2-ton and 4-ton industrial boilers, with C-type belt drive and D-type coupling drive arrangements available.
Y10-21 is a single-suction centrifugal induced draft fan used on industrial boiler flue-gas systems. The fan is installed downstream of the boiler and gas-cleaning equipment to overcome resistance through the furnace, heat-transfer surfaces, dust collector and flue system.
The catalog configuration covers No.8 and No.9 fans at 1450 rpm, with separate reference duties for smaller and larger industrial boiler systems.

Temperature and Dust Must Be Checked Together
No.8 Reference
Catalog reference medium temperature: up to approximately 220°C.
No.9 Reference
Catalog reference medium temperature: approximately 200°C.
Dust Collection
The catalog requires a dust-removal device with efficiency of at least 85% upstream of the induced draft fan.
Gas temperature changes density and therefore affects pressure, shaft power and motor selection. Always provide the actual flue-gas temperature when requesting selection.

08 / Selection Information
What to Send for Y10-21 Selection
01 · Airflow - Required operating airflow in m³/h.
02 · Pressure - Required total or static pressure and its measurement basis.
03 · Gas Temperature - Normal and maximum flue-gas temperature.
The catalog data supplied for this series covers No.8 and No.9 configurations.
What airflow range is available?
The reference catalog range is approximately 4,215 to 16,252 m³/h.
What pressure does Y10-21 provide?
Reference catalog duty points cover approximately 2,303 to 3,312 Pa total pressure.
What is the difference between C and D drive?
C-type uses V-belt transmission, while D-type uses a coupling between the fan and motor shafts.
Is a dust collector required upstream?
The original catalog specifies an upstream dust-removal device with efficiency not lower than 85% to reduce dust entering the fan and improve service life.
Can the discharge direction be specified?
Yes. The catalog provides multiple outlet orientations including 0°, 45°, 90°, 135°, 180° and 225°. Confirm the required direction before manufacturing.
