Fig. 1 shows a schematic structural diagram of an embodiment of the present application. Fig. 2 is a top view of fig. 1. As shown, a combustion apparatus 100 can be applied to a burn test.

The combustion apparatus 100 includes a water tray 10, a combustion partition 20, and an oil filler hole 30.

Wherein water is injected into the tray 10 to form a water storage layer 11.

A combustion baffle 20 is provided on the water tray 10. The combustion partition 20 has a plurality of combustion units 40, each combustion unit 40 having a hollow structure, substantially perpendicular to the horizontal plane 12 of the water storage layer 11. The bottom 41 of each combustion unit 40 extends below the water level 12 of the reservoir 11. The plurality of combustion units 40 divide the water level 12 of the reservoir 11 into a plurality of separate combustion zones.

The oil filling hole 30 is formed in the water tray 10 and is located in a vertical projection of each combustion unit 40. Specifically, one oil injection hole 30 is provided in each combustion unit 40, and combustion oil 50 can be injected into the combustion unit 40 through the oil injection hole 30. The oil filling hole 30 is arranged on the water tray 10 and is positioned at the bottom of the water storage layer 11, and under the isolation effect of the water storage layer 11, the oil filling hole 30 is not contacted with burning oil during burning, so that the safety of the whole oil path system can be ensured.

In a fire test of an automobile part or other object, a plurality of combustion units 40 corresponding to the projected area are selected according to the projected shape of the automobile part placed on the combustion partition 20. The burning oil 50 is injected into the oil injection hole 30 below the selected burning unit 40, and after the burning oil 50 floats up to the water level 12 of the water storage layer 11, the burning oil 50 is ignited to perform the burning test of the automobile parts. The combustion area consisting of the plurality of combustion units 40 can be adjusted according to the shape and size of the test piece to be burned. In addition, the combustion oil 50 may be injected into the oil injection hole 30 through an oil gun. It will be readily appreciated that combustion oil 50 may be selectively injected into the desired combustion unit or units 40. Upon ignition, the combustion oil 50 in the combustion unit 40 may be ignited manually by a human or automatically by an electrically controlled ignition system.

Further, the combustion partition 20 includes a diaphragm 21 and a vertical partition 22. The transverse and vertical partition plates 21, 22 are arranged in a crossing manner, and a combustion unit 40 is formed between two adjacent transverse partition plates 21 and two adjacent vertical partition plates 22.

The cross section of the combustion unit 40 may be one or more of a circle, an ellipse, a triangle, a square, a rectangle, and a polygon.

Preferably, the oil injection hole 30 is located at a central position within the vertical projection of the combustion unit 40. Ensuring that the injected combustion oil 50 in the oil filling hole 30 floats up and enters the designated combustion unit 40 without being deviated into other combustion units 40 around.

Preferably, the combustion oil 50 is continuously or intermittently injected into the oil injection hole 30 under the combustion unit 40, and when the combustion oil 50 on the water level 12 of the water storage layer 11 in the combustion unit 40 is ignited, the combustion oil 50 in the combustion unit 40 can be continuously combusted due to the fact that the bottom of the combustion unit 40 is continuously injected with the combustion oil 50. The injection amount of the combustion oil 50 in the designated combustion unit can be selected according to the actual requirements of the combustion test of the automobile parts, so as to control the combustion time.

Preferably, the combustion oil 50 is a combustion oil such as gasoline, diesel oil, or aviation kerosene.

Referring to fig. 1 and 2, a combustion apparatus 100 according to the present application is described as follows:

the combustion unit 40 is selected according to the projected shape of the automobile parts placed on the combustion bulkhead 20.

The fuel oil 50 may be selectively injected into the fuel injection hole 30 under the combustion units A1 to A4, and the fuel oil 50 naturally floats up to the water level 12 of the water storage layer 11. The combustion oil 50 in the combustion units A1 to A4 was ignited to perform a fire test of the automobile parts. It can be understood that the distance between the automobile parts and the combustion partition 20 is adjustable, when the distance between the automobile parts and the combustion partition 20 is larger, the combustion oil 50 can be additionally injected into the combustion units B1 to B11 to ignite the combustion oil 50 in the combustion units B1 to B11, so that the combustion area can be enlarged, and the adjustment of the combustion area can be completed.
