The invention relates to a method of extinguishing a fire of complex category with flame burning accompanying with smoldering of products of burning. Besides, the invention concerns a fire extinguishing system embodying said method and a fire extinguishing generator used, in particular, in said system. The method of extinguishing a fire provides introduction of a flow of flame inhibiting aerosol into the center of burning, introduction into the center of burning or to the element contacting with the center of burning of a cooling agent having endothermic properties and maintenance of the temperature in the center of burning lower than the temperature of resuming of flame chain reactions in the center of burning, and introduction into the center of burning of additional portions of cooling agent, introduction of additional portions of cooling agent is being continued until the moment, when own maximal temperature of the center of burning will become lower than the temperature of resuming of burning reactions in the products of burning, that results in liquidation of smoldering of products of burning and in extinguishing the fire as a whole.
La présente invention concerne un procédé d'extinction de feu de type complexe associant flamme vive et combustion lente du matériau. L'invention concerne également, d'une part un système d'extincteur mettant en oeuvre ce procédé, et d'autre part un extincteur convenant notamment dans un tel système. Le procédé consiste à introduire au coeur du feu un aérosol anti-flamme, ou à appliquer sur l'élément au coeur du feu un agent refroidissant présentant des propriétés endothermiques, puis à maintenir la température au coeur de la combustion à un niveau inférieur à la température de reprise des réactions en chaîne de la flamme au coeur de la combustion. Le procédé consiste ensuite à introduire au coeur de la combustion un complément d'agent de refroidissement, et ce jusqu'à ce que la température intrinsèque du coeur de la combustion descende en dessous de la température de reprise des réactions en chaîne de la flamme au coeur de la combustion. Cela permet d'anéantir le feu couvant dans les produits combustibles et d'éteindre le feu dans sa totalité.
