Frequently Asked Questions

What is the primary role of a blower or fan in a furnace system?
The blower is the heart of the furnace’s air circulation system. Its primary roles are to: Induce Combustion: Supply precise amounts of combustion air to the burner. Remove Exhaust: Safely expel flue gases through the stack (induced draft). Recirculate Heated Air: Move hot air throughout the furnace chamber to ensure uniform temperature distribution, which is critical for process consistency and product quality.
Why is an Air Handling Unit (AHU) used with a furnace?

An AHU is used when the furnace process requires precise control over the quality and condition of the air being introduced or recirculated. This includes:

  • Filtering incoming air to prevent contaminant buildup on the product or heating elements.
  • Pre-heating combustion air to improve furnace efficiency.
  • Controlling humidity in specific heat-treating processes.
  • Providing tempered make-up air to replace exhaust.
What types of fans are used in furnace systems?
  • Induced Draft (ID) Fans: Located at the furnace outlet to pull flue gases through the system.
  • Forced Draft (FD) Fans: Located at the furnace inlet to push combustion air into the burner.
  • Recirculation Fans: Located inside the furnace to circulate air for
  • uniform temperature.
    Quench Fans: Used in heat treatment furnaces for rapid cooling of components.
How are these components designed to handle thermal expansion?

Critical design features include:

  • Expansion Joints between the fan and ductwork.
  • Float-fit or keyed impeller mounting to allow shaft and impeller to expand at different rates.
  • Sliding Plinth Bases for drive motors to maintain belt tension.
  • CFD (Computational Fluid Dynamics) analysis to predict hot spots and stress points.
What are the most common causes of fan failure in a furnace?
  • Imbalance: Caused by buildup of material on the impeller or wear.
  • Bearing Failure: Due to heat, improper lubrication, or misalignment.
  • Fatigue Cracking: From thermal cycling (repeated heating and cooling).
  • Corrosion/Erosion: From aggressive flue gases or particulate abrasion.
What routine maintenance is essential for furnace fans and AHUs?
  • Regular Vibration Analysis: To detect imbalance and bearing issues early.
  • Bearing Temperature Monitoring: Using RTDs or thermocouples.
  • Visual Inspections: Through access doors for signs of buildup, corrosion, or cracks.
  • Lubrication Schedule: Strict adherence to high-temperature grease specifications.
  • Filter Maintenance: For AHUs, replacing pre-filters and bag filters to maintain airflow.
