Air Burner Comparison
Trench Burner vs. FireBox
To decide between a Trench Burner and a FireBox or BurnBoss, first consider your goal.
The primary purpose of an Air Curtain Burner is pollution control; in particular, the reduction of smoke from open burning. The high velocity air curtain traps the smoke particles momentarily causing them to re-burn and be further reduced. The air then continues into the firebox or trench to agitate and oxygenate the fire. The result is a burn that is cleaner and faster than open burning.
With a Trench Burner, the burning is done in-ground in an earthen pit that is dug on-site. This will work well, if the air curtain manifold is in the correct position (angle) and the walls of the trench are vertical. If either of these factors is compromised, the pollution control capabilities of the Trench Burner will be less effective.
With a Firebox and BurnBoss, the burning is done above-ground. The FireBox burn area is open to the ground on the bottom and lined on all four sides with castable thermo-ceramic walls. The FireBox comes completely assembled and requires no set-up. The burning operations are typically more efficient (faster and cleaner) in a FireBox compared with a Trench Burner, as the burn chamber does not rely on the accuracy of an earthen trench that is subject to deterioration.
