Abstract
A method and apparatus for eliminating fog on a stadium, on airports, highways and the like, dissolves the fog by discharging a mixture of warm and cold air, respectively produced by a warm air, direct combustion generator and a double suction centrifugal ventilator. The warm air generator and cold air ventilator are placed side-by-side with a portable housing and separated by an internal wall. The mixture of warm and cold is discharged such that discharge satisfies the relation: 10 Kcal/h:m.sup.3 of ventilated air/h at a velocity less than or equal to 20 m/s.
Claims3
A method for dissolving fog on large open areas, such as landing strips for aircrafts, stadia, harbors and the like, comprising the subdivision of the area in sub-areas, in each of which a directional jet of a mixture of warm and hot air is discharged, characterized by the fact that each jet is obtained by a predetermined mixture of a slightly forced stream of hot air and of a more strongly forced stream of un-heated air, said discharged jet, having a duly adjustable amplitude, being discharged in a direction substantially parallel to the ground, said discharged jet being such as to contain about 10 kcal per m.sup.3, while the jet speed is less than or equal to about 20 m/sec.
A device for dissolving fog on large open areas, such as landing strips for aircrafts, stadia, harbors and the like, comprising:
- a housing for producing a warm and hot air mixture, said housing having longitudinal outer walls and a front and back wall, said housing further comprising an inner longitudinal wall separating the inner space of the housing into first and second parallel chambers;
- said first chamber housing a centrifugal motor fan of a high discharge head, in order to produce a strong stream of cold air;
- said second chamber housing a hot air generator associated with a fan having a discharge head which is less than that of said fan housed in said first chamber;
- said front wall having a first outlet orifice for said first chamber and a second outlet orifice for said second chamber;
- and wherein
- said front wall is connected with an aerodynamically tapered connection section, said connection section and front wall forming a diffusion-mixing chamber of decreasing cross sectional-shape starting from the front wall and terminating in a discharge orifice for the discharge of the jet of mixed and diffused air, whereby said jet of mixed and diffused air reaches said discharge orifice in a substantially horizontal direction.
