PORTABLE AIR CURTAIN DESTRUCTOR MINIMIZES AIR POLLUTION

SPECIFICATIONS TO ELIMINATE THE OPEN BURNING OF CLEARING AND GRUBBING MATERIALS ON HIGHWAY CONSTRUCTION PROJECTS ARE NOW REQUIRED IN CONTRACTS WITH THE ARKANSAS STATE HIGHWAY DEPARTMENT. THE AIR CURTAIN DESTRUCTOR CIRCULATES A CURTAIN OF HIGH VELOCITY AIR ABOVE THE FIRE BURNING IN THE PIT. AS THE AIR CURTAIN STRIKES THE FAR SIDE OF THE PIT, IT IS DEFLECTED DOWNWARD AND HORIZONTALLY INTO THE FIRE, THEREBY CAUSING HIGHER TEMPERATURES TO INSURE COMPLETE COMBUSTION. PARTICLES OF UNBURNED MATERIALS MOVING UPWARD ABOVE THE BURNING MATERIAL ARE CAUGHT BY THE HIGH VELOCITY AIR CURTAIN AND RETURNED INTO THE PIT. ONLY THE GASEOUS PRODUCTS OF COMBUSTION ESCAPE THROUGH THE HIGH VELOCITY CURTAIN OF AIR. /AUTHOR/
