Abstract

The invention discloses a combustion box capable of adjusting a gas environment. And through the design of the box body, a relatively closed combustion environment can be realized. The top of the structure is provided with the exhaust port, mixed gas of nitrogen and oxygen is injected from bottom to top, and gas in the box body can be replaced in all directions before a combustion test, so that the gas environment in the combustion box meets test requirements. The gas proportion can be obtained by adjusting the nitrogen assembly and the oxygen assembly. The combustion box is suitable for combustion instruments, such as a cone calorimeter, of which the gas environment cannot be adjusted. When the combustion box is combined with a combustion instrument for use, the exhaust port can be used as an exhaust channel and can also be used as an ignition channel, and thermal load and electronic ignition of the combustion instrument can be completed through the exhaust port.

Description

technical field [0001] The invention relates to the technical field of material combustion testing, in particular to a combustion box capable of regulating the gas environment. Background technique [0002] When a fire breaks out, the oxygen in the fire scene will be consumed rapidly, forming a more complex anoxic environment. The current experimental technology has not quantitatively controlled the oxygen concentration in the fire scene environment to conduct in-depth research on it. In order to maintain public safety and reduce casualties and property losses caused by fire, it is necessary to conduct in-depth research on the combustion performance of materials under unconventional oxygen content conditions and determine their fire hazards. Combustion characteristics of materials is an important point in the research of fire science. Materials can be the source of ignition or the main combustibles in a fire. During the combustion process, when the material is under differe...
