FIRE-EXTINGUISHING PLANT Russian patent published in 2005 - IPC

FIELD: fire fighting, particularly means for generating aerosol fire inhibitors for extinguishing fires into closed space.

SUBSTANCE: fire-extinguishing plant comprises two pyrotechnical charges for gas-aerosol mixture generation. Pyrotechnical charges are provided with protective shells and arranged in vessels connected in back-to-back manner and spaced one from another. One vessel is of plate-like shape and charges are connected to the vessel by gypsum cement layer filling space defined by vessel flanging. Ignition block is installed between the charges. Another vessel is cylindrical and mates to plate-like vessel flanging diameter. Ratio between charge masses is 3:7. The plant may perform automatic operation in two modes, namely in intensive gas-aerosol generation mode with simultaneous pyrotechnical cartridge charge end burning in both vessels to provide a certain aerosol inhibitor concentration in the space, and in slow gas-aerosol generation mode in which pyrotechnical cartridge charge burns only in cylindrical vessel to increase aerosol inhibitor concentration up to predetermined value.

EFFECT: possibility of automatic operation in two modes.
