Recommended boiler exhaust velocities.
|Exhaust Gas from Boiler||Recommended Boiler Exhaust Velocity|
|Ducts at minimum load ||< 4.0 ||< 13 |
|Stack at minimum load ||< 5.0 ||< 16 |
|Boiler with one-step burner (on - off) ||5.0 - 8.0 ||16 - 26 |
|Boiler with two-step burner (high - low) ||10 - 15 ||31 - 49 |
|Boiler with modulating burner ||15 - 25 ||49 - 82 |
|To keep the surface free from soot the velocity should exceed ||3.0 - 4.0 ||9.8 - 13 |
