CA 2436272

A method for subduing a fire (70) is disclosed. This method is performed by operating a jet turbine (20), having an exhaust (22), to direct the exhaust (22) into a moving front of the fire (72), generally against the movement of the front of the fire (72). A retardant (30), preferably dust, is directed from a supply tank (40) into the exhaust (22), through a pressurized conduit (42). Alternately, dust or other material (32) is lifted from the land around the fire (70) and blown into the fire (70), extinguishing the fire (70) or decreasing its intensity. To completely extinguish the fire (70), it may be necessary to further douse the fire with either or both water and a second retardant.

La présente invention décrit une méthode d'extinction d'un incendie (70). Cette méthode est exécutée par la commande d'une turbine à réaction (20) munie d'une tuyère d'éjection (22) pour diriger les gaz d'échappement (22) sur le front d'un incendie en mouvement (72), en général contre le mouvement dudit front (72). Un agent retardateur (30), de préférence de la poussière, est dirigé d'un réservoir d'alimentation (40) dans la tuyère (22) au moyen d'une conduite pressurisée (42). Une autre solution consiste à prélever de la poussière ou autres matériaux (32) du sol autour de l'incendie (70) et de la ou les souffler sur le feu (70) pour éteindre ce dernier ou en diminuer l'intensité. Pour éteindre complètement l'incendie (70), il peut être nécessaire d'arroser aussi l'incendie avec de l'eau, un second agent retardateur ou les deux méthodes.
