Zahn, Susan M.. 2005. The Use of Air Curtain Destructors for Fuel Reduction and Disposal. 0551 1303P. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 6 p.
The San Dimas Technology and Development Center (SDTDC) evaluated the use of air curtain destructors (ACDs) as an efficient, environmentally friendly, technically feasible alternative in fuel reduction and disposal. SDTDC's industry research found two companies, Air Burners LLC, of Palm City, FL, and McPherson Systems, Inc., of Tifton, GA, that manufacture the self-contained box-styled ACDs. These ACDs are air curtain incineration systems with a refractory-lined firebox. An engine supports the attached fan, which creates an air curtain across the top of the unit. During SDTDC's evaluation, both manufacturers' ACDs efficiently disposed of large quantities of forest vegetation (fuels) at very high temperatures, while releasing very little emission particulate matter. This safer alternative to open burning is viable throughout the year except when fire danger is too high. All emissions evaluations and supporting data was provided by Ron Babbitt and the staff from U.S. Department of Agriculture (USDA) Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory, Missoula, MT.
