Abstract

In the method for extinguishing fires in enclosed spaces, pre-cooled combustion products are introduced into an enclosed space until in the enclosed space there is an atmosphere that prevents combustion. An ecologically acceptable and fire-inhibiting medium that is not detrimental to health is formed by oxidizing the combustion products completely by an oxygen-containing oxidizing agent prior to cooling. An apparatus for implementing the method has a housing (1) which is divided by a transversely running partition wall (11) having at least one wall opening (15). At the at least one wall opening (15) a mixing tube (8) is mounted coaxially with respect to a discharge nozzle (2) connected to a combustion chamber (14), the end of the mixing tube remote from the partition wall (11) opening into the atmosphere. The space (7) between the mixing tube (8) and the inner wall of the housing (1) is filled with a coolant. Inlet openings (9) are formed in the wall of the housing (1) between the partition wall (11) and the end face of the combustion chamber (14) facing the partition wall (11). The discharge nozzle (2) is in the form of a jet pipe (6) and extends through the wall opening (15) into the mixing tube (8), a gap being present between the jet pipe (6) and the mixing tube (8).
