Problems solved by technology

This method is simple and convenient, but due to the poor pressure and poor control accuracy during the gas distribution process, it is easy to cause the problem of poor gas distribution repeatability and accuracy; the gas explosion phenomenon is basically judged by observing the flame propagation at present, but for combustible gases involved When it is hydrogen, the flame burning in the air is light blue, and the flame propagation speed is very fast, so the phenomenon is difficult to observe, resulting in large errors in the explosion limit test results

And accurate evaluation of the explosion performance of the composite gas is realized.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a hydrogen composite gas explosion limit test system and a test method. Background technique [0002] In the existing composite gas explosion limit test method, the gas preparation process is generally prepared by the partial pressure method, that is, the concentration of each component in the composite gas is determined according to the proportion of the respective pressures. This method is simple and convenient, but due to the poor pressure and poor control accuracy during the gas distribution process, it is easy to cause the problem of poor gas distribution repeatability and accuracy; the gas explosion phenomenon is basically judged by observing the flame propagation at present, but for combustible gases involved When it is hydrogen, its flame burning in the air is light blue, and the flame propagation speed is very fast, so the phenomenon is difficult to observe, resulting in large...
