A multifunctional fire test furnace system device

Abstract

The invention relates to a multifunctional fire test furnace system device which comprises a heating furnace body, a fuel system, an electronic ignition and control system, a combustion control system, an air supply system, a smoke exhaust system, a smoke characteristic test system, a temperature field and radiant heat flux test system, a furnace chamber and flue pressure test system, a pump-type water-spraying fire extinguishing system, an experiment image acquisition system and a loading device. The fire test furnace can carry out multi-angle experiment simulation on building structure system conditions under the high-temperature fire effect, and can study ignition characteristics, fire propagation characteristics and combustion rules of a building structure system as well as smoke flow characteristics, propagation rules and influencing characteristics and rules of the technique of smoke prevention and evacuation on fire propagation; and the research result can provide reliable theoretical analysis, experimental basis and scientific reference for fire protection performance design of various building structures and building systems.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, in particular to a multifunctional fire test furnace system device. Background technique [0002] In recent years, my country's high-rise buildings have sprung up in every major city across the country. With the construction and use of these high-rise buildings, the potential danger of fire in high-rise buildings has become increasingly prominent. Among the approximately 250,000 fires that occur in my country every year, building fires account for about 80%, especially in high-rise building fires and ancient building fires. The number of fires and the proportion of economic losses are increasing year by year. Fire has become a A major disaster that endangers people's lives and property. [0003] For some building systems, collapse may occur when a fire breaks out and withstands the high temperature of combustion for a long time. The cooling effect will lead to the rapid cooling and cra...

Problems solved by technology

[0003] For some building systems, collapse may occur when a fire breaks out and withstands the high temperature of combustion for a long time. The cooling effect will lead to the rapid cooling and cracking of reinforced concrete, the bearing capacity will be greatly reduced and collapse will occur (such as the Hengyang fire in Hunan, etc.); for some building systems, although they did not collapse in the fire, the high temperature of the fire will damage the building structure system. too serious to be used obsolete
