A method of achieving positive pressure in a fire resistance furnace

  • J. H. McGuire


Positive pressure may be developed at any level in a furnace by locating the flue outlet below instead of above that level and by restricting the area of the flue outlet. Maintaining a constant air supply to the burners is often desirable. Various safety factors are of great importance.
