Abstract
A method of and a device for extinguishing burning gases forming by evapoion of a low-temperature liquid gas stored in tank spaces and ignited upon entering atmosphere by random effects is described. The method and device include means for introducing a hydrocarbon (halone) such as difluorochlorobromomethane or trifluorobromomethane or mixtures thereof as an extinguishing agent into burning low-temperature gases underneath the root of the flame for achieving a chemical reaction with the burning low-temperature gases.
Claims9
A method of extinguishing burning gases forming by evaporation of a low-temperature liquid gas stored in tank spaces and ignited upon entering atmosphere by random effects, comprising the steps of
- a. introducing a halogenated hydrocarbon selected from the group consisting of CF.sub.2 ClBr CF.sub.3 Br and mixtures thereof as an extinguishing agent into burning low-temperature gases underneath the root of the flame for achieving a chemical reaction with the burning low-temperature gases, and
- b. reliably gasifying the extinguishing agent by the radiation energy of the flame.
A device for extinguishing burning gases forming by evaporation of a low-temperature liquid gas stored in tank spaces and ignited upon entering atmosphere by random effects, comprising a tubular gas duct having a free gas-discharge end and being arranged to guide gases forming by evaporation of a low-temperature liquid gas in a tank space from said tank space into the atmosphere, and inlet sockets arranged at a point downstream from the gas-discharge end of the tubular gas duct and adapted to eject halogenated hydrocarbon serving as an extinguishing agent.
