Abstract
Fire extinguishing method, especially for spaces intended for the storage of aircraft, such as hangars, in which method a fire extinguishing medium, especially a liquid mist, is sprayed via at least one first nozzle (2) in the area, seen in a vertical direction, between an object (1) to be protected/extinguished, such as an aircraft, and the floor (3) or equivalent af the storage space. At least one first nozzle (2) is arranged to spray mainly in the area between the object (1) to be extinguished, such as an aircraft, and the floor (3) of the storage space or equivalent at least in a horizontal plane mainly in one first direction.
Claims20
In a fire extinguishing method for at least one of a space, aircraft storage space or hangar in which at least one of fire extinguishing medium or liquid mist is sprayed via at least one first nozzle (2) in an area between at least one of an object (1) to be protected/extinguished or an aircraft and at least one of a floor (3) or equivalent of the space, aircraft storage space or hanger, the improvements wherein:
- the at least one of fire extinguishing medium or liquid mist is sprayed via the at least one first nozzle (2) mainly in an area between the at least one of the object (1) or aircraft and the floor (3) or equivalent and at least in a horizontal plane mainly in one first direction;
- and
- the at least one of fire extinguishing medium or liquid mist is sprayed via at least one other first nozzle (2) at a distance from and serial to the at least one first nozzle at least in a horizontal plane substantially in the one first direction so that the sprays from the one and other first nozzles boost each other by a suction produced by the sprays.
In fire extinguishing apparatus for at least one of a space, aircraft storage space or hangar comprising at least one first nozzle (2) so directed as, in a activated state, to spray at least one of a fire extinguishing medium or liquid mist in the area between at least one of an object (1) to be protected/extinguished or an aircraft and a floor (3) of the at least one of space, aircraft storage space or hanger, the improvements wherein:
- the at least one other first nozzle (2) is arranged for the spray mainly in an area between the at least one of the object (1) or an aircraft and a floor (3) of the at least one of the space, aircraft storage space or hanger and at least in a horizontal plane mainly in one first direction;
- and
- at least one other first nozzle (2) is arranged to spray at least one of the extinguishing medium or liquid mist at a distance serially from the one first nozzle (2) at least in a horizontal plane substantially in the one first direction so that the sprays (2′) from the first nozzles (2) boost each other by a suction produced by the sprays.
