The principle of the air curtain concept is optimized with this Air Burners design. High velocity air is directed across and downwards at an angle into the pit creating the air curtain on top and a rotational turbulence within the pit itself. The rotational turbulence provides an oxygen enriched environment within the combustion zone which accelerates the combustion process by raising the temperatures within the pit up to approximately 1,800º F (approx. 1,000º C).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The 40 foot unit is a fully self-contained trailer mounted system that includes a power plant, mechanical drive system, blower fan and fuel tank. The unit has manifolds in length of 40 feet or 12 meters, that deliver the “air curtain” for trench burning.

 

The trench is constructed using a backhoe, excavator or similar equipment. The earthen trench is built by excavating down into the soil to achieve a trench that is the length of the manifold: 8-10 feet (2.5-3 meters) wide. The trench depth should be equal to the width, but can be more if practical. Trench Burners do not operate well in soil not conducive to digging the pit, as with very sandy or very rocky soil. Additionally, a low water table may prevent the construction of a proper trench. Where these conditions exist you may build a dike type pit.
