  • Method and apparatus for extinguishing fires
    Patent number: 6089326
    Abstract: A method for extinguishing fire, wherein a gas an aerosol mixture is fed into a space includes steps of igniting a pyrotechnic composition that ensures a predetermined temperature profile during burning and a predetermined composition of the gas and aerosol mixture completely oxidizing the combustion products of incomplete combustion of the pyrotechnic composition by causing them to pass through a bed of catalytically active substances, which is located in the zone of the maximum temperature of the temperature profile of combustion of the pyrotechnic composition, with the temperature remaining constant by redistribution of said profile; cooling the combustion products and completely oxidizing them by reacting with substances having high heat absorbing capacity, concurrently with the filtering of the combustion products according to composition of the gas phase and particle size of the aerosol phase.
