As a result, the use scope of the Bunsen burner has gradually expanded from the original laboratory-only to laboratories and some manufacturing enterprises.

[0003] However, in the actual use of ordinary Bunsen burners, there are the following problems: 1. With propane, acetylene, methane, butane and other combustion gases being used as fuels of ordinary Bunsen burners, compared with the original coal gas, different combustion gases have different mixing ratios with air when fully burned, and an air flow regulating device capable of adjusting the air intake is required. The ordinary Bunsen burner can only adjust the size of the coal gas intake, but not the air intake; 2. Sometimes it is necessary to adjust the length of the burning flame at the head of the Bunsen burner, but the ordinary Bunsen burner cannot adjust the length of the burning flame; 3. When using an ordinary Bunsen burner, no matter which of the above fuels is used, smoke and dust are sometimes easy to appear during use, especially at the lamp head; at the same time, the burning flame at the head of the ordinary Bunsen burner cannot be windproof, so that the burning flame is easily blown by the wind and deviates from the area actually required to be heated.
