METHOD FOR PUTTING smoldering fires

摘要

quenching method smoldering fires, comprising supplying to the room object glow array gaseous extinguishing material composition to achieve indoor glow array oxygen of a predetermined concentration of the material, characterized in that the preliminary to develop measures for providing fire safety of the object space in which the treated kept smoldering materials define qualitative and quantitative composition of the gaseous products of thermal decomposition of materials prone to decay, and in the case vozniknove Ia smoldering fire in a room space object is introduced into the extinguishing gas composition in the amount of calculation in the room creating oxygen concentration determined from the condition extinguishing smoldering fire! Cox = Cox.min,! wherein Cox.min - minimum oxygen concentration required for combustion of most fuels (with less Cox.min) the gaseous product of the thermal decomposition material,% vol.! at this time, the fire extinguishing gas composition into the room to extinguish array glow hearth material is determined from the ratio of! τeh = τred.ox + Hmas / Vlim.sm,! wherein τred.ox - while the fire extinguishing gas composition to achieve in a room where there was a smoldering fire, the oxygen concentration of Cox.min, about%. ! Hmas - the height of the array of glow material in the room, m; ! Vlim.sm - limit for smoldering oxidizing environment at a maximum flow rate of the initial oxygen concentration in the room object m / s.
