ID fan

Since 1978, we are a trusted ID Fan Manufacturer in India delivering high-performance Induced Draft Fans for boilers and industrial applications.

ID fan full form is Induced Draft Fan.

An ID fan is a critical industrial fan used to remove flue gases from boilers, furnaces, and power plants by creating negative pressure (draft) inside the system.

This ensures:
✔ Efficient fuel combustion
✔ Proper airflow balance
✔ Safe exhaust through chimney

ID Fan Working Principle

The ID fan working principle is based on induced draft (suction mechanism):

  1. Flue gases are generated inside the boiler
  2. The ID fan creates negative pressure inside the furnace
  3. Hot gases are pulled through boiler passes and ducting
  4. Gases pass through ESP / Bag Filter
  5. Clean gases are discharged through chimney


Main Components of an ID Fan

A high-performance boiler ID fan consists of:

ID Fan Impeller

Handles dust-laden gases and provides energy to airflow

Casing (Volute)

Converts velocity into static pressure

Inlet Cone

Ensures smooth airflow entry

Shaft & Bearings

Transmits power and supports rotation

Motor

Drives the entire system

Dampers / IGV

Controls airflow and system efficiency

ID Fan Impeller Design

The ID fan impeller is designed to withstand extreme conditions:

✔ Backward Curved Blades – High efficiency, low energy consumption
✔ Radial Blade Design – Best for dust & abrasive particles
✔ Wear Resistant Construction – Longer service life

For proper selection of ID fan in boiler or power plant, the following parameters are critical:

  • Air Flow (CFM / m³/hr)
  • Static Pressure (mmWC / Pa)
  • Temperature (°C)
  • Dust Load
  • Efficiency (%)

FAQs?

What is ID fan full form?

Induced Draft Fan

What is ID fan used for?

To remove flue gases and maintain negative pressure

What is difference between ID and FD fan?

An ID Fan (Induced Draft Fan) and an FD Fan (Forced Draft Fan) are both essential in boiler systems, but they perform opposite functions.

Conclusion:

An ID Fan (Induced Draft Fan) is a vital component in industrial boilers and thermal power plants, ensuring efficient combustion, proper draft control, and safe removal of flue gases.
