About ID Fan
Gyantosh's Induced Draft (ID) Fans evacuate flue gases from the boiler, drawing combustion products through the furnace, heat-recovery surfaces, and pollution-control equipment and discharging them up the chimney. By maintaining the correct furnace draft, the ID fan is central to stable combustion, safe operation, and reliable performance of the whole boiler system.
Each fan is engineered for the specific gas volume, temperature, static pressure, and dust loading of your boiler and APC train. Robust, dynamically balanced impellers, wear-resistant liners for dust-laden gas, and heavy-duty bearings ensure long, vibration-free service life even in demanding solid-fuel boiler applications.
Fans are supplied with matched motors and drives, dampers or variable-frequency control for draft regulation, and mounting arrangements to suit the plant. Backward-curved and radial impeller designs are offered depending on efficiency and dust-handling requirements.
GyanTosh supplies, installs, and services ID fans (and matched FD/PA fans) as part of complete balance-of-plant and boiler solutions, backed by over two decades of engineering experience.

ID Fan Specification
Fan Technology
The fan draws flue gas through the furnace, heat-recovery surfaces, and APC equipment, maintaining the negative draft needed for stable combustion.
Liners and hard-faced impellers resist erosion from dust-laden flue gas, extending life in solid-fuel applications.
Inlet dampers or a variable-frequency drive modulate gas flow to hold furnace draft steady across the boiler load range.
A dynamically balanced impeller and heavy-duty bearings deliver smooth, low-vibration, reliable operation.

Advantages of a ID Fan
Maintaining the correct furnace draft is essential for stable, efficient combustion and safe boiler operation.
Wear-resistant liners and hard-faced impellers withstand the erosive, dust-laden flue gas of solid-fuel boilers.
VFD draft control matches fan power to actual demand, cutting auxiliary power consumption compared with damper throttling.
Each fan is sized to the exact gas volume, temperature, and static pressure of your boiler and APC train.
Dynamic balancing and heavy-duty bearings give smooth, dependable 24×7 operation.
GyanTosh supplies replacement and upgraded ID fans for existing boilers to restore draft performance.
