SMOKELESS FLAME PIT SPEEDS TREE STUMP DESTRUCTION

A "CURTAIN" PRODUCED BY FANS IN TWO BLOWER UNITS THAT WHIP FLAMES INTO A SMOKELESS FORM OF INCINERATION, IS USED IN DISPOSING TREE STUMPS FROM CONSTRUCTION PROJECTS WITHOUT VIOLATING THE ORDINANCE AGAINST AIR POLLUTION. THIS METHOD IS CONSIDERED MORE SATISFACTORY, DEPENDABLE AND ECONOMICAL THAN OTHER ACCEPTABLE METHODS. THE MECHANISM OF THE ACTION INVOLVES THE CREATION OF A CURTAIN OF HIGH VELOCITY WIND THAT ENTERS AN 8 FT. WIDE TRENCH AT AN ANGLE AND CHURNS THE FLAMES INTO WHITE HEAT. SMOKE CAUGHT IN THE MAELSTROM IS CIRCULATED THROUGH THE FLAMES UNTIL ALL PARTICUATE MATTER IS BURNED. ONLY CLEAR HOT AIR LEAVES THE PIT. A PROTECTIVE MOUND ROUND THE PIT WARDS OFF STRAY BREEZES. THE EQUIPMENT USED IN THE PROCESS CONSISTS OF 2 BURNERS OF DIFFERENT SIZE CONNECTED INTO A SIMPLE OPERATING UNIT THAT FORCES 44,000, CFM. OF AIR ACROSS THE TRENCH. EXPERIENCES IN A 75-ACRE SANITARY LANDFILL IN FAIRFAX COUNTY, ARE DESCRIBED. STUMP REMOVAL AND BURNING PRODUCTION (ON A CONSTRUCTION SITE) WITH THE HELP OF AN ATTACHMENT TO A HYDRAULIC BACKHOE IS ALSO DISCUSSED.
