Top Advantages of Customized Centrifugal Fans & Blowers in food processing units
An induced draft fan is an important part of any industrial process. The main function of an induced draft fan is to ensure the smooth flow of air through a ventilation or combustion system by removing flue gases, smoke, dust, and hot air from boilers, furnaces, kilns, etc. It does this by creating negative pressure inside the system.
Since forced draft fans blow in the gases, an induced draft fan draws out the gases, which is useful in the handling of high-temperature gases and gases with contaminants.
What Is an Induced Draft Fan?
Generally, an induced fan is attached at an outlet or exhaust of a system like a boiler or a furnace in industries. The most notable purpose of an induced draft fan is to remove gases, which are exhausted through a combustion process. This ensures a balance, making the combustion process efficient while preventing gases from leaking into a work environment.
Since these fans are frequently required to handle hot, corrosive, and particulate matter-containing gases, they are widely made of hardy materials and are typically designed for high durability. Many industries require an Industrial ID Fan Manufacturer who designs fans according to their specifications.
Step-by-Step Procedure: How Does an Induced Draft Fan Work?
Understanding the working process of an induced draft fan is easier when broken down into clear steps:
Step 1: Combustion or process generates exhaust gases
The fuel used in boilers, furnaces, or kilns burns in a combustion process and includes flue gases, smoke, ash particles, and heat.
Step 2: Fan Creates Negative Pressure
The induced draft fan is fixed at the discharge end, which starts rotating as the fan begins to work by the suction of the exhaust gases.
Step 3: Gas Flow Through Ducting
Exhaust gases may flow through ducts, exchangers, or other equipment such as scrubbers and electrostatic precipitators before being conveyed to the fan.
Step 4: Exhaust Discharge
The fan discharges the gases safely through a chimney or a stack to the atmosphere while adhering to the necessary standards.
Step 5: Continuous Pressure Balance
This continuous removal of gases ensures that the pressures throughout the system remain constant, in turn averting any backflow and making the system efficient as well.

Key Applications of Induced Draft Fans
Induced draft fans are widely used across industries where controlled exhaust and ventilation are essential. Some major applications include:
Power Plants
It is used in thermal power plants to extract flue gases from the boilers.
Cement & Steel Plants
Essential for handling dust-laden gas, as well as high-temperature gas from clinker and metals processing.
Chemical and process industries
Helps to safely remove corrosive vapours and fumes from reactors, dryers, and processing equipment.
Boilers and Furnaces
Ensures proper draft, fuel efficiency, and prevents gas from accumulating inside the combustion chamber.
Pollution Control Systems
Usually works in conjunction with bag filters, scrubbers, and ESPs to effectively move gases through filtration devices.
Benefits of Using an Induced Draft Fan
- Improves combustion efficiency
- Enhances workplace safety
- Supports emission control compliance
- Handles high-temperature and dusty gases
- Ensures consistent airflow and pressure control
