An Induced Draft Fan (ID Fan) is a critical component in industrial systems, particularly in combustion processes such as boilers and furnaces. It creates a negative pressure within the combustion chamber, effectively drawing flue gases out of the system and ensuring efficient combustion and emissions control.
Key Features
Negative Pressure Generation: ID Fans operate by generating a vacuum that pulls exhaust gases from the combustion chamber, facilitating the removal of flue gases through the stack or chimney.
High Efficiency: These fans are designed to handle high temperatures and corrosive gases, achieving high operational efficiency while maintaining system pressure.
Durable Construction: Built to withstand harsh operating conditions, ID Fans are typically constructed from robust materials that resist wear and corrosion.
Variable Speed Control: Many models come with variable frequency drives (VFDs) that allow for precise control of airflow based on operational demands.
Versatile Applications: Commonly used in power plants, waste incineration facilities, and industrial boilers to manage exhaust gases effectively.
Working Process
Air Intake: The fan draws ambient air into the system.
Exhaust Gas Removal: It creates negative pressure that pulls flue gases from the combustion chamber through ducts.
Discharge: The gases are expelled through a stack or flue, ensuring compliance with environmental regulations.
