The San Dimas Technology and Development Center (SDTDC) investigated the use of air curtain destructors (ACDs) as an efficient, environmentally friendly, and technically viable means of disposing of slash, wood, and other burnable waste materials. ACDs should be considered an additional alternative to current fuel reduction methods and disposal of road clearing debris such as pile burning, chipping, landfill disposal, and prescribed fire. SDTDC's research of the industry indicates that one company, Air Burners LLC, manufactures both self-contained and trench ACDS. Their self-contained ACDs are basically ski-mounted air curtain incineration systems including a refractory lined firebox that does not require any setup or teardown. Their trench burners are trailer-mounted air curtain incineration system requiring a pit or earthen trench that functions as a firebox. Both types of burners can efficiently dispose of large quantities of forest waste products at very high temperatures with very little air emissions. This safe and clean method of burning allows its operation nearly any time of year except when fire danger is too high. In addition to burning safely and cleanly, volume reductions of approximately 95 to 98 percent are achieved. The ash may be used as a soil amendment that can be spread on the forest floor.
