Embodiment

[0052] combine figure 1 , a burning conical flame Bunsen burner of the present invention includes a Bunsen burner body 4, and the Bunsen burner body 4 is mainly composed of a lamp body segment and a lamp nozzle 44 connected together. The lamp body section includes an outer casing and an inner cavity for mixed flow channeling of the gas, and the lamp nozzle 44 is used for ejecting the gas to form a flame.

[0053] The inner cavity of the lamp body section is provided with a filler layer 422, a flow equalizer 423 and a first sintered mesh 432 from bottom to top, and the filler layer 422 and the flow equalizer 423 are located on the upper side of the third sintered mesh 421 below the second sintered mesh 424 In between, that is, the third sintered mesh 421 is used to carry the filler layer 422, and the second sintered mesh 424 is used to cover it.

[0054] A base 41 is connected to the bottom of the lamp body section, and a gap space is formed between the base 41 and the third s...

Abstract

The invention discloses a Bunsen burner with a tapered flame burned and a flame propagation speed measuring method, and belongs to the field of flame detection. The Bunsen burner comprises the Bunsenburner body, the Bunsen burner body is mainly formed by connecting a burner body section and a burner nozzle, the inner cavity of the burner body section is provided with a packing layer, a flow equalizing plate and a first sintering net from bottom to top, the packing layer and the flow equalizing plate are located between a second sintering net on the upper side and a third sintering net on thelower side, and the first sintering net is arranged above the second sintering net by an interval. According to the Bunsen burner and the method, the inner cavity and the burner nozzle of the Bunsen burner body are improved, so that the flow stabilization effect is applied on the passing mixed gas, the flame emitted from the burner nozzle is approximately tapered, and then the detection precisionof the flame propagation speed can be improved.

Description

technical field [0001] The invention relates to the technical field of flame detection, in particular to a combustion cone flame Bunsen burner and a flame propagation velocity measurement method. Background technique [0002] The flame propagation velocity of laminar premixed combustion refers to the velocity of the plane flame front relative to the unburned gas in the direction perpendicular to the flame surface. The purpose of studying flame propagation velocity is to better characterize the laminar flame velocity of syngas fuel. [0003] Laminar flame speed is an important parameter of flammable mixtures as it contains fundamental information on reactivity, diffusivity and exotherm. The value of the flame velocity has a significant effect on the flame's tendency to flash back and blow out, and controls other key combustion characteristics such as the spatial distribution of the flame. [0004] Although laminar flame speed is simple to define, it is difficult to measure ...
