The ACDs manufactured by Air Burners LLC have been used worldwide for several types of applications. They are used in forest fuel management and wildfire mitigation efforts, in the construction industry to reduce debris from land clearing and demolition operations,
and at landfill sites to maximize costly space by reducing wood waste and similar burnable waste streams. They are also used in disaster recovery for clearing the aftermath from storms or floods.

Description
The main operating principle of the ACD is the high velocity air (curtain) blown across and into the upper portion of the combustion chamber (figure 2). This powerful curtain of air has two effects. First, the high volume of air causes overoxygenation of the fire, and secondly the high velocity airflow over the combustion chamber entraps particulates (smoke), which then completes combustion in the combustion chamber, thus limiting emissions and smoke. The high turbulence along with increased combustion time and temperatures in excess of 1,800 °F results in complete combustion and significantly reduced air emissions. Reduced air emissions lower impact on nearby residents, smoke sensitive individuals, and decrease smoke-related inversions during fall and winter. In addition, the high temperatures and oxygen-rich environment burn everything from green fuels to red slash.

Equipment
Air Burners LLC manufactures two types of ACDs: self-contained skid-mounted firebox systems that do not require any setup or teardown; and trench burners that require setup and an earthen pit or trench which functions as the firebox.

Skid-Mounted Systems
The skid-mounted ACD as shown in figure 3, is a self-contained system that includes a refractory walled firebox, diesel engine power plant, mechanical drive system, blower fan, and fuel tank. These ACDs are engineered to be transportable by a lowboy or similar drop-deck trailer. The transportability increases the flexibility of bringing the ACD to the wood waste source, rather than hauling the waste to a fixed location for processing. These ACDs are ready for use as soon as they are offloaded at the jobsite. The refractory lined firebox allows for controlled burning without the need for an earthen pit or trench. The forward equipment deck shown in figure 3 supports the diesel engine, the fuel tank, the direct drive system to operate the fan, and the fan. An air nozzle manifold is mounted on one side of the firebox. The wood waste is loaded over the top of the ACD on the side opposite the manifold (figure 4).
