Example Embodiment

[0029] The present invention will be further described in detail with reference to the accompanying drawings.

[0030] Among them, such as figure 1 Shown is an existing large-scale combustible inclined combustion characteristic experimental device developed by the China University of Mining and Technology. The device can perform different sizes (maximum size 3m*1.5m) and different inclination angles (15°, 30°, 45°, 60°, 75° and 90°) inclination (vertical) combustion characteristics of combustibles. The experimental process can output the mass loss rate of combustibles, smoke toxicity, and sample surface temperature in real time, but only in certain Combustion experiments under a specific gas environment and a specific side wall structure cannot achieve various experimental conditions such as different gas environments (different oxygen concentrations, different gas pressures) and different side wall structures.

Description

technical field [0001] The invention is used to measure the characteristic parameters in the combustion process of combustibles arranged vertically in different gas environments (different oxygen concentrations, different gas pressures) and different side wall structures. It is mainly used in fire protection teaching and scientific research work, and belongs to the experiment In the technical field of teaching or scientific research instruments, it specifically refers to a vertical combustion characteristic experimental device with a controllable gas environment and a side wall structure. Background technique [0002] Vertical fire spread refers to the fire spread behavior in which the direction of spread is consistent with the direction of gas flow. Generally speaking, vertical fire spreads quickly and has a high risk of fire. It has always been an important research topic in the field of building fire prevention. At present, scholars at home and abroad have systematically ...
