An apparatus, system and method for suppression of fires are provided. In accordance with one embodiment of the invention, a housing is provided with a first opening (or set of openings), a second opening (or set of openings) and a flow path defined between the first and second openings. A fire-suppressing gas is produced, such as from a solid propellant composition, and is introduced into the flow path in such a way that a volume of ambient air is drawn from a location external to the housing, through the first opening and into the flow path. The volume of ambient air may be subjected to an oxygen- reducing process and mixed with the fire-suppressing gas to form a gas mixture. The gas mixture is discharged from the flow path through the second opening and into an associated environment for suppression of a fire located therein.

L'invention concerne un dispositif, un système et un procédé servant à lutter contre l'incendie. Selon un mode de réalisation, un boîtier comporte une première ouverture (ou ensemble d'ouvertures), une deuxième ouverture (ou ensemble d'ouvertures) et un trajet d'écoulement défini entre la première et la deuxième ouverture. Un gaz d'extinction, tel qu'une composition de poudre propulsive, est introduit dans le trajet d'écoulement, de façon à aspirer un volume d'air ambiant depuis un emplacement extérieur au boîtier, à travers la première ouverture, afin de le faire pénétrer dans le trajet d'écoulement. Ce volume d'air ambiant peut être soumis à un traitement oxydoréducteur et mélangé avec le gaz d'extinction afin de créer un mélange gazeux. Ce dernier est évacué depuis le trajet d'écoulement à travers la deuxième ouverture afin de pénétrer dans le milieu dans lequel s'est développé l'incendie.
