Forced Draft Advantages:
- Easy Maintenance: Fans and motors at ground level, accessible.
- Quieter Operation: Fan noise contained within structure.
- Good for High Static Pressure: Centrifugal fans handle system resistance well.
- Less Fan Corrosion: Fan not exposed to saturated exhaust air.
- .
Induced Draft Advantages:
- Higher Efficiency: Better air distribution, lower horsepower/ton.
- Less Recirculation: High-velocity vertical discharge.
- Better Cold Weather Operation: Draws air in, doesn’t force cold air.
- Industry Standard: More design experience, parts availability.
