Abstract： |
The Bunsen burner capable of realizing several kinds of flame forms is one kind of gas burner. The Bunsen burner includes seat, burner pipe, fuel gas inlet pipe and combustion-supporting gas inlet pipe. The burner pipe is one concentric pipe comprising inner pipe of 2-50 mm inner diameter and outer pipe, the interval between the inner pipe and the outer pipe is 1-100 mm, and the length difference between the inner pipe and the outer pipe is -200 mm to +1000 mm. By means of selecting the different lengths and diameters of both the inner pipe and the outer pipe, the present invention can obtain various flames in different forms and this perfects further the teaching demonstration and heat science research one Bunsen burner. |
