FIRE-EXTINGUISHING METHOD AND MULTIJET FIRE-EXTINGUISHING POWDER FLOW FORMING DEVICE FOR ABOVE METHOD IMPLEMENTATION (VARIANTS)

摘要

FIELD: fire-fighting equipment, particularly adapted to deliver fire-extinguishing material.;SUBSTANCE: method involves forming at least one set of gas-and-powder jets directed to fire site, wherein axes of adjacent jets in each set are directed at equal angles one relative another. The angle does not exceed half of jet spray angle. Three embodiments of gas-and-powder flow forming device are also disclosed.;EFFECT: increased fire-extinguishing reliability due to provision of high uniformity of specific fire-extinguishing powder discharge over the full surface to be protected.;12 cl, 7 dwg
