METHOD OF AEROSOL FIRE EXTINGUISHING IN PARTIALLY CLOSED SPACES AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1998 - IPC

FIELD: methods and devices designed for volume fire-extinguishing based on use of aerosol fire-extinguishing compound produced by burning of solid fuel composition of oxidizer and reducer. SUBSTANCE: solid fuel composition in powdery state is located in flexible tube-module from polymer material. Solid fuel composition charge is ignited simultaneously over the entire length of tube-module with the help of electric wires located along the charge or thermosensitive safety fuse. These measures provide for prompt supply of aerosol fire-extinguishing substance and possibility of protection of highly nonhermetic objects. Use of tube-module of flexible material provides for their possible location in hard-to-reach places (underhood space of automobile, under-the-floor cable localities and ducts, etc). EFFECT: higher efficiency. 2 cl, 1 dwg
