PYROTECHNICAL DEVICE AND PROCESS FOR EXTINGUISHING FIRES

摘要

The present invention pertains to a pyrotechnical device and process for extinguishing fires, especially in case of a forest fire or a surface fire. The extinguishing device comprises two flexible fire hoses (1, 2) arranged side by side and transversally relative to the direction from which the danger (5) comes and designed so that both ends can be obturated. A fire suppressant (3, 4) is placed in or upon each hose and its ignition causes same to be sprayed and directed into the fire. In order to guarantee a targeted jet of the fire suppressant in the direction from which the danger comes, the impulse (I¿1?) from the first hose (1) turned in the direction opposite the danger is meant to be stronger than the impulse (I¿2?) from the hose turned in the direction from which the danger comes. For the various hose (2) crosssections, the quantity of blasting agents depends on the diameter of the hose turned to the danger, taking into account the density ? of the fire suppressant under the inventive formula.
