The fire spread, to a great extent, dependence. The relationship between the flow velocity of the flue gas and the temperature of the flue gas, the flow direction of the fire at high temperature. Large frame structure building area is large, the initial fire range is limited. The building can not be demolished in the fire. Liberal arts reasonable application of fluid mechanics principle of scientific money first to the location of the fire will quickly spread to the whole space. Action throughout the building of smoke and heat, the implementation of the advantage of Arts and want to minimize the fresh air coming in, slowed down the development, at the same time, through the jetting gun water leads to the decrease of temperature.
If at the same time, breaking the windows and doors, under the direction of flame and smoke give extended application. If the window of the roof, but now fire-resistant limits time range and to ensure the safety of the conditions, the old combustion acting on the top of the window heat accumulation is derived. At the same time, the roof and ground crew contact strength, roof and floor demolition of the old water to cool the cover of synchronous implementation. Lonely. Leads to the fire limit time of the fire burning, the roof is not right.
