The embodiment of the invention relates to an adjustable hedging flame experiment system, the adjustable hedging flame experiment system comprises a first nozzle, a second nozzle, an alignment assembly and an adjusting assembly, the second nozzle and the first nozzle are spaced and oppositely arranged, the alignment assembly is connected with the first nozzle, and the adjusting assembly is connected with the alignment assembly. The aligning assembly is used for driving the first nozzle to move so that the first nozzle can be aligned with the second nozzle, and the adjusting assembly is connected with the second nozzle and the aligning assembly. The adjusting assembly is used for driving the alignment assembly and / or the second nozzle to move so as to adjust the distance between the first nozzle and the second nozzle. According to the adjustable hedging flame experiment system provided by the embodiment of the invention, the experiment equipment can be quickly adjusted, the experiment time is saved, the experiment cost is reduced, and meanwhile, large-batch repeated experiments can be carried out.
Description
technical field [0001] The invention relates to the technical field of fuel combustion experiments, in particular to an adjustable opposing flame experiment system. Background technique [0002] As a basic experimental system for the study of combustion, hedging flame plays an important role in the field of combustion, especially in the field of basic research, where key parameters such as flame propagation velocity, flame elongation rate, and extinguishing limit of fuel can be obtained. In the experiment, in order to ensure the accuracy of the experiment, the upper and lower nozzles need to be adjusted in the center, and the distance between the upper and lower centers is less than 0.1mm. In the actual experiment process, due to the limitation of machining accuracy and installation limitation, the centering adjustment of the upper and lower nozzles is difficult and time-consuming. In addition, in order to determine the relevant characteristics of the fuel, the distance bet...
