摘要： A process for the simultaneous utilization of low expanded foam and medium expanded foam produced by respective generators thereof, for the extinction of fires, from liquefied gas comprising transporting the medium expanded foam by the faster traveling low expanded foam in order to provide a high velocity of flow of the medium expanded foam. The low expanded foam is produced by a plurality of generators disposed beneath a single generator of medium expanded foam and inclined with respect thereto to direct the jets of low expanded foam into the lower part of the jet of medium expanded foam.

摘要： The present invention discloses an improved compressed air foam pumping/generation system in which the compressed gas that is used to drive a pumping system is re-utilized and introduced into the outlet manifold to more efficaciously generate a compressed gas foam. A further improvement could include a three-way valve which controls the flow of the compressed gas so that the present invention could be used to generate CAF, aspirated foam (with use of an appropriate nozzle), gels or operate as a simple pump. Additional optional components include a check valve and flexible connection material.

摘要： A method of proportioning a finished foam at or near a hazard comprising proportioning and delivering a first finished foam to the hazard, determining if the first finished foam extinguishes or suppresses the hazard, if not, selecting an amount of a fluorinated additive, and proportioning a foam solution including the selected amount of the fluorinated additive to form a fluorinated finished foam. A foam injection system is also disclosed.

摘要： The invention relates to an optimized foam former (1) for foaming a foam-water concentrate, which foam former consists of a curved grate having diamond-shaped openings (13) and sharp edges (12). The structure of the foam former increases the foam formation and ensures uniform distribution of the foam over a large area. Existing water sprinklers having a nozzle (3) and a spray disk (2) can be provided with the foam former (1) and thus converted into foam sprinklers in a simple manner. The foam former (1) is arranged in such a way that the foam former (1) protrudes beyond the spray disk (2) toward the nozzle (3).
