Hybrid Manual-Electronic Safety Bunsen Burner

The application discloses an aviation alternative fuel Bunsen burner capable of sufficiently mixing different kinds of gases, which comprises a mixing chamber, an air inlet assembly and a nozzle assembly, the two ends of the mixing chamber are respectively provided with a mixing chamber inlet and a mixing chamber outlet, and a gas mixing structure is arranged in the mixing chamber; the air inlet assembly comprises a gas path connecting nozzle, the gas path connecting nozzle is detachably installed at the mixing chamber inlet, a plurality of air inlet joints are arranged on the gas path connecting nozzle, and a gas supply device is communicated with the tail end of the air inlet joint; the nozzle assembly is detachably installed at the mixing chamber outlet, and the mixed gas in the mixing chamber is sprayed out through the nozzle assembly. The application can sufficiently and uniformly mix the gases, so that better and more ideal experimental effects are achieved; meanwhile, the air inlet assembly of the application can be changed according to the kinds of the gases to be mixed, and the air inlet joints are increased, so that the effect of sufficiently and uniformly mixing a plurality of gases is achieved.

The application relates to the field of atomic spectrum regulation, and particularly discloses a sodium flame shadow brightness adjusting method based on the action of a strong magnetic field, which comprises the following steps: building an experimental system composed of a low-pressure steam sodium lamp, an electromagnet, a Bunsen lamp, a spectrometer, an attenuation sheet and a Tesla meter; arranging salt outside the gas outlet of the Bunsen lamp and igniting the salt to form a sodium-containing flame, making the light emitted by the low-pressure steam sodium lamp pass through the sodium-containing flame, and forming an initial shadow under the condition of no magnetic field; adjusting the driving current of the electromagnet, so that the sodium-containing flame area is under the condition of different magnetic field actions; detecting the change of the transmission light intensity at the same wavelength, and comparing the change with a preset adjusting target; and determining the target magnetic field action condition when the preset adjusting target is met. The application can realize the stable adjustment of the sodium flame shadow brightness.
