An ID (Induced Draft) fan is a type of fan used in industrial processes, particularly in systems like boilers, furnaces, and air pollution control equipment. Its primary function is to induce or draw flue gases out of the system and into the stack or chimney. Here’s a breakdown of its key aspects:

Function

• Flue Gas Removal: The ID fan pulls flue gases from the combustion chamber or furnace and pushes them through the stack. This helps maintain the necessary airflow and combustion conditions within the system.
• Pressure Control: By inducing draft, the ID fan helps control the internal pressure of the combustion system, ensuring that the combustion process operates efficiently and safely.

Design and Operation

• Location: Typically located downstream of the combustion chamber and before the flue gas exits through the stack.
• Construction: ID fans are usually designed with backward-inclined or centrifugal blades to handle high temperatures and corrosive gases. They are built to withstand harsh conditions and have robust construction to ensure reliability.
• Drive Mechanism: They can be driven by electric motors or other power sources, and the drive mechanism needs to be designed to handle the fan's load and operating conditions.

Applications

• Boilers: In steam and hot water boilers, ID fans remove flue gases from the furnace and help regulate the combustion process.
• Industrial Furnaces: They assist in the removal of exhaust gases and maintain proper draft conditions.
• Pollution Control: In systems like scrubbers or electrostatic precipitators, ID fans help move gases through the pollution control equipment.

A 30 HP Industrial ID Fan (Induced Draft Fan) is a heavy-duty centrifugal blower designed to handle flue gas extraction and airflow control in industrial processes, particularly in boiler systems, furnaces, and dust collection applications. ID fans create a controlled negative pressure (vacuum) in combustion chambers, drawing flue gases through ducts, filtration systems, and chimneys to ensure efficient combustion and safe exhaust discharge.

This fan typically features a 30 HP electric motor and belt-driven or direct-drive arrangement, with a robust centrifugal impeller made of cast iron or steel for long-lasting performance under continuous duty. The housing and blades are built from mild steel (MS) or stainless steel (SS) to resist corrosion and thermal stresses encountered in flue gas environments.

Standard specifications for a 30 HP industrial ID fan include fan speeds around 1440 RPM, airflow capacities in the range of 12,000–14,000 m³/hr, and static pressure ratings designed to match the resistance of boiler and ductwork systems. These fans are often foot-mounted on a concrete foundation for stability and quiet operation.

Common applications include steam boiler exhaust, industrial combustion systems, and dust or fume exhaust in manufacturing plants, making them essential for maintaining efficient airflow and regulatory compliance in heavy industries.
