FIELD: fire fighting equipment. ^ SUBSTANCE: invention refers to fire prevention, more specifically to fire-extinguishing installations using gas-aerosol flame retardants generated by pyrotechnic block combustion and supplied to a protected space in an orderly way, preferentially by water crafts and transport vehicles. The generator contains coaxial case and pyrotechnical block fixed in flooring cement layers with an in-between annular reversible heat exchanger formed by two perforated metal envelopes with an internal one being matched with a receiver; and an ignition assembly adjoining a free end face of the block, and an outlet cover. The ignition assemble is integrated in a median slot from an open end face of the block which is enclosed in a polymer film casing and rests through a foam plastic spacer on a rod mounted in the diametrical perforations of an inferior envelope of the heat exchanger bearing longitudinal edges for the block diametre, while the case comprises a bearing bracket wherein ignition assembly telecommunication clamps are fixed. ^ EFFECT: ensured higher functional reliability and efficacy of the generator of more simple and technological design and expanded range of use thereof. ^ 2 cl, 2 dwg |
