Boiler ID & FD Fans
In modern industrial plants, efficient air and flue-gas management are critical for performance, safety, and regulatory compliance. Boiler ID (Induced Draft) Fans and FD (Forced Draft) Fans play a central role in maintaining proper combustion, pressure balance, and emission control across boilers used in power generation, cement manufacturing, chemicals, textiles, and food processing industries.
At Mahesh Fabricators, decades of experience in industrial air movement technology ensure that every ID and FD fan is engineered for reliability, efficiency, and a long service life under demanding operating conditions.
Understanding Boiler ID Fans (Induced Draft Fans)
Boiler Induced Draft (ID) Fans are installed on the flue-gas outlet side of the boiler. Their primary function is to draw exhaust gases out of the boiler furnace, creating a slight negative pressure inside the combustion chamber.
Key Functions of ID Fans
ID fans are especially critical in coal-fired boilers, biomass boilers, waste heat recovery systems, and process heaters, where precise control of flue gas flow is essential.
Difference Between ID Fan and FD Fan in Boilers
- Position: Flue gas outlet
- Function: Removes exhaust gases
- Pressure: Creates negative pressure
- Temperature Handling:High-temperature gases
- Role in Combustion:Gas evacuation
- Position: Air inlet
- Function: Supplies fresh air
- Pressure:Creates positive pressure
- Temperature Handling: Ambient or preheated air
- Role in Combustion: Air supply
Both fans work together to balance furnace pressure, ensuring smooth and efficient boiler operation.
Importance of Proper ID & FD Fan Selection
- Reduced boiler efficiency
- Excessive power consumption
- High vibration and noise
- Frequent breakdowns and downtime
- Required airflow (CFM / m³/hr)
- Static and total pressure
- Gas temperature and dust load
- Fuel type and boiler capacity
- Continuous or variable load operation
At Mahesh Fabricators, each ID and FD fan is custom-engineered after detailed process analysis to ensure optimal performance.
