SYSTEM AND METHOD FOR LIMITING SPREAD OF WILDFIRE

摘要

The document relates to a method for limiting the spread of a wildfire, comprising: defining a fire limiting boundary (4); positioning a plurality of droplet generating units (1) along the fire limiting boundary (4); connecting said droplet generating units (1) to a liquid source (3); and activating said droplet generating units (1) so that a mist is applied to a border area (41) along said fire limiting boundary (4), said border area (41 ) having a width, as seen in a direction across the fire limiting boundary, which is 20-200 m, preferably 50-150 m, wherein said actuation of said droplet generating units (1) being initiated before the wildfire (5) is at least 500 m, preferably at least 1000 m, at least 2000 m, at least 5000 m, or at least 10,000 meters, from fire limiting boundary (4). Each droplet generating unit (1) provides a mist throw length (L) of 20-200 m, preferably 20-30 m, 30-40 m, 40-50 m, 50-60 m, 60- 70 m, 70-80 m, 80- 90 m, 90-100 m, 100-120 m, 120-140 m, 140-160 m or 160-180 m, and each droplet generator (10) operates in an angled position relative to the frame (11) at an angle of 10-60 degrees seen to a horizontal plane, preferably at an angle of 20-50 degrees seen to a horizontal plane.
