Problems solved by technology

The original gas fire source porous burner can only produce a vertical upward flame, and cannot change the direction of the flame
In addition, changing the shape of the fire outlet to irregular polygons and arcs on the original gas fire source porous burner will increase the difficulty of the process and the economy will be poor
Therefore, in the above scenario, as a simulated fire source, it cannot meet the demand

Embodiment Construction

[0025] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0026] A burner device whose orientation and shape can be used to simulate a vertical fire source includes three main parts: a burner outer casing, a gas fire source porous burner, and a burner base.

[0027] see figure 1 , a new type of burner device whose direction and shape can be adjusted to simulate a vertical fire source. The burner shell 1 used in it is composed of three layers, the outermost layer is a layer of iron sheet 2, and the inside is pasted with 0.008m thick fireproof The board 3 is 0.01m thick thermal insulation cotton 4 inwardly, which can effectively reduce the heat loss inside the housing.

[0028] see figure 1 , take the square flame outlet of 20cm on the vertical plane as an example, the burner housing 1 is a cuboid, the length of the upper and lower bottom surfaces is 21.8cm, the width is 23.6cm, and the height is 22.8c...

Abstract

The invention discloses a burner device with the adjustable orientation and shape and used for simulating vertical fire sources. The burner device comprises an outer burner shell, a gas fire source porous burner and a burner base. The porous burner is placed on the burner base. The upper portion of the porous burner is covered with the outer shell. The inner diameter of the outer shell is in seamless connection with the porous burner. According to the burner device, the vertical fire sources with openings of any orientation and shape can be simulated by changing the shape and size of the shelland the orientation of an opening, and an effective device is provided for studying behavior evolution processes of opening overflow fire under various circumstances and the physical law thereof. Thegas fire source porous burner, the outer shell and the burner base which are three main components of the burner device are flexible to disassemble and can be assembled in multiple modes, and use isflexible. The whole burner device is provided with rolling wheels, thereby being convenient to move. The burner base is provided with a telescopic rod, and the height can be adjusted continuously. Selection of the experimental environment and the requirement of the height of a fire outlet are easy to meet.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and specifically relates to a burner device whose direction and shape can be used to simulate a vertical fire source, and provides a method for experimentally simulating the spread of a fire opening in various situations, and studying its evolution process and its physical laws. an effective method. Background technique [0002] In fire science, porous gas burners are widely used as simulated fire sources. The gas ignition source is less affected by the flame radiation feedback during the combustion process and can maintain a constant heat release rate, which provides an effective way to establish a theoretical model for the stable combustion of the ignition source. Tang Fei et al. compared the gas ignition source with McCaffrey's theoretical model of flame height under different ignition source powers, and found that the fitting index of plume temperature rise in the intermittent plume area...
