Advantages of Forced Draft Burners over Venturi Burners
Bailey forced draft burners are mounted up off the floor for convenient easy access. Most venturi burner designs require the operator to crawl on the floor to adjust the burners. Because the Bailey has only two burner ports, there is no heat loss or re-oxidation problems which is typically the case with multiple burner venturi kilns where the burner ports can not be sealed. Venturi kilns are ultra sensitive to the general atmosphere and prone to wide variations in reduction results. Besides the damper, there is no flexible control for internal circulation on a venturi kiln. Heat gets trapped in the top. Debris can fall into the burner ports on the floor and obstruct the flame entry. To view the burners you have to crawl on the floor.
