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.

Description

technical field

[0001] The invention relates to a gas lamp, in particular to a Bunsen burner used for teaching demonstration experiments and heating samples, and belongs to the technical field of laboratory equipment. Background technique

[0002] In thermal science majors and laboratories of various colleges and universities, Bunsen burners are used for teaching demonstration experiments and heating samples. Because its temperature is higher than the flame of alcohol lamp and its structure is simple, it is widely used. At present, the commonly used Bunsen burner only achieves qualitative control through valve adjustment for fuel gas and supporting gas, and cannot accurately match the combustion volume. In order to make the gas burn better, the disclosed technical solution is to add a replaceable Combustion sheet, in order to regulate the intake air volume of supporting gas, as the utility model that the patent No. is 88210014. There are many similar products in foreign co...
