The invention discloses a double-slot gas fire source experimental device with adjustable angles and intervals. The device comprises slot gas burners, a displacement platform, four burner brackets, burner fixing boxes, a rotating handle, a rotating shaft and an angle ruler. Every two burner brackets form a set for use, the burner brackets are arranged on the displacement platform in a sliding mode, each set of burner brackets is rotationally provided with one burner fixing box through the rotating shaft, each burner fixing box is internally provided with one slot gas burner, and one end of therotating shaft is connected with the rotary handle and provided with the angle ruler. According to the double-slot gas fire source experimental device with the adjustable angles and intervals, the angles and intervals of fire sources can be adjusted at the same time, the power and the size of the fire sources can be changed, and system experimental research on double-slot fire source burning under the influence of multi-factor coupling is facilitated.
Description
technical field [0001] The invention relates to the technical field of multi-ignition combustion and fire, in particular to a double-slot gas ignition experimental device with adjustable angles and distances. Background technique [0002] Combustion with double-slot ignition sources occurs frequently in actual fires, often causing extreme fire behaviors such as flame mergers and fire whirlwinds, which significantly increase the fire hazard. In the spread of forest fires, the fire front formed by the ignition of two rows of shrubs is a typical double-slot fire source combustion scene, and the double fire fronts often promote each other to cause a larger-scale fire spread. In a building fire, the fire overflow adjacent to the opening overflow is also a typical double-slot fire source combustion scene, and the double fire overflow tends to gather with each other to accelerate the three-dimensional spread of the fire. Carrying out experimental research on double-slot fire sourc...
