Full Form of "FD Fan"

FD stands for Forced Draft.

• Forced Draft Fan: A fan that pushes air into the boiler furnace (under positive pressure) to supply combustion air. It operates before the furnace, forcing air through the air heater and burner system.

Breakdown of Your Product Description

You are looking for a "Forced Draft Boiler FD Fan" with the following specifications:

• Material: Q235 (Chinese standard carbon structural steel, similar to ASTM A36 or S235JR). This indicates the housing and impeller are made of low-carbon steel, suitable for standard industrial air at normal temperatures.
• Configuration: Single Inlet (air enters from one side of the fan housing, vs. double inlet which enters from both sides).
• Type: Industrial Centrifugal Blower (uses a rotating impeller to increase air velocity and pressure).

Summary of the Product (Technical Definition)

"Q235 Single Inlet Industrial Centrifugal Blower for Forced Draft Boiler" means:

• Function: Forces ambient air into a boiler for combustion.
• Material: Q235 carbon steel (standard industrial grade).
• Design: Single-sided air intake, centrifugal design (high pressure, moderate flow).
• Application: Industrial boilers, furnaces, or thermal systems requiring forced combustion air.

Key Specifications to Look For (When ordering)

If you are sourcing this fan, ensure the supplier provides:

1. Flow Rate (m³/h or CFM) – How much air you need.
2. Static Pressure (Pa or mmH₂O) – The resistance it must overcome (boiler draft loss).
3. Motor Power (kW/HP) – Matched to the fan curve.
4. Speed (RPM) – Direct drive or belt-driven.
5. Temperature Rating – Standard Q235 handles up to ~80°C (176°F) for ambient air; higher temps require alloy steel.

Note: For boiler FD fans handling hot flue gas (e.g., from air preheaters), Q235 is not suitable. You would need Q345R or stainless steel for high-temperature resistance. Q235 is only for cold air intake.
