Good Model with Porous Powder Extinguishers for Vessels of Extinguishing Agents
Incompleteness of an exit substances from powder fire extinguishers owing to a design lack, reduces efficiency of fire extinguishers several times. A principal cause of it is propensity of a powder to grouping and funnel formation on an input in a siphon tube at movement of forcing out gas. Results of the analysis of efficiency of powder fire extinguishers with a siphon tube and models holding a patent of the fire extinguisher with porous capacity are resulted. Experimental and mathematical methods of an estimation of efficiency of fire extinguishers are put in a research basis.
