Abstract
A fire extinguishing apparatus (10) producing a mist of water vapour with a median droplet diameter of between 50 and 500 micron for extinguishing fires in a confined risk area. The mist being generated through nozzles (18) operating at <2000 kPa (i.e. low pressure). The fire extinguishing apparatus using less than 1.0 litres of water per cubic meter of the risk area in which the fire is contained (i.e. a small volume of water).
Claims54
A fire extinguishing apparatus for extinguishing a fire located in a risk area, the fire extinguishing apparatus comprising:
- spray means for spraying non-flammable liquid therefrom into the risk area,
- delivery means for passage of the non-flammable liquid for delivery thereof under pressure to said spray means,
- detector means for detecting the presence of a fire in the risk area, and
- fluid delivery control means to allow delivery of the non-flammable liquid via said delivery means to said spray means following actuation of said fluid delivery control means,
- wherein, in use,
- said spray means sprays the non-flammable liquid therefrom to form a mist having a median droplet size of substantially 500 microns or less,
- said non-flammable liquid is sprayed from said spray means at a rate of substantially 1 liter or less per minute per cubic meter of volume of the risk area, and
- said non-flammable liquid is sprayed from said spray means into said risk area to form said mist the non-flammable liquid,
- such that said mist of non-flammable liquid droplets can be applied to the fire to extinguish the fire.
A method of extinguishing a fire in a risk area comprising the steps of:
- detecting the presence of a fire in the risk area,
- actuating fluid delivery control means for delivery of a non-flammable liquid,
- delivering the non-flammable liquid under pressure to spray means, and
- directing a spray of the non-flammable liquid from the spray means into the risk area, characterized by
- spraying the non-flammable liquid into the risk area to form a mist having a median droplet size of substantially 500 microns or less,
- spraying the non-flammable liquid at a rate of substantially 1 liter or less per minute per cubic meter of volume of the risk area, and
- spraying the non-flammable liquid into the risk area to form said mist of the non-flammable liquid,
- such that said mist of non-flammable liquid droplets is applied to the fire to extinguish the fire.
