An upstream control valve 51 is provided on the upstream side of the fluid pipeline 1; a downstream control valve 52 is provided on the downstream side of the fluid pipeline 1 and before the collection point; an outlet control valve 53 is provided on the collection pipeline 2.

[0084] At least one of the two fluid lines 1 has an air pump 7 installed at its inlet 11. The air pump 7 is located at the bottom of the combustion test platform and is connected to the fluid line 1 via an air pump valve 71.

[0085] like Figures 1-5 As shown, the combustion test platform includes two fluid lines 1, with inlets 11 of the two fluid lines 1 connected to an air pump 7 and a combustible gas, respectively. By setting up two fluid lines 1, one can be connected to the air pump 7 to allow air to participate in the combustion experiment, while the other can be connected to a gas cylinder 8 or other pipelines to provide combustible gas for the combustion experiment. This allows for the use of various gas sources and types for testing, enhancing the functional versatility of the combustion test platform.

[0086] In other embodiments, the combustion test platform includes three fluid lines 1. One inlet 11 of the three fluid lines 1 is used to connect to an air pump 7, and the other two inlets 11 are used to connect to different combustible gases.

[0088] Specifically, a flashback valve is installed on the manifold 2, and a flame arrester 10 is installed at the outlet control valve 53. The flashback valve is installed to promptly block the flame from propagating backward through the manifold 2 during combustion, thus preventing a safety accident. The flame arrester 10 is installed at the outlet control valve 53 to prevent flashback, effectively preventing flashback from reaching the fluid line 1. In other possible embodiments, other flame arresting devices may also be installed to prevent flashback from occurring in the pipeline during detection.

[0089] In this embodiment, the combustion test platform includes a frame with an internal space. At least two fluid lines 1 are housed within this space. Flow meters 41 are mounted on the bottom of the frame via brackets 140, and multiple flow meters 41 are spaced apart in the height direction. The frame includes a panel 120 and a top plate 110. An outlet 21 passes through and extends beyond the top plate 110. Flow indicators 42 and pressure indicators 43 protrude from the panel 120, and an observation plate 130 is located on the top of the top plate 110. By placing the fluid lines 1 within the internal space of the frame, the flow path of the fluid lines 1 can be arranged more clearly.

The outlet 21 protruding from the top plate 110 facilitates observation of the combustion flame, and the flow indicators 42 and 43 protruding from the panel 120 facilitate observation of the test data.

At least one of the two fluid pipelines 1 is used to connect the combustion gas, while the other pipelines are closed, and the outlet 21 is ignited. By observation and image measurement, information such as flame shape, color, and combustion speed under different flow and pressure conditions can be obtained.

[0092] The combustion test platform is used for premixed combustion performance tests of fixed-component gases. Two or more fluid pipelines 1 supply gas simultaneously, the control unit 5 adjusts the fluid ratio, and a premixed burner 9 is installed at the outlet 21.
