Apr 18, 2023 · Given the fuel of the Burner burner is methane, when the air hole of a burner burner is fully opened, striking back will occur. I observed that the strike-back flame is green in colour and produces loud noises. Are there any reasons for the green flame colour and noises?
With too much air, the flame may burn inside the burner tube; that is, it may strike back. The Meker and Fisher burners, variations of the original Bunsen burner, have metallic grids to increase the turbulence of the mixture and keep the flame at the top of the tube.
If using matches, strike the head of the match against the striking strip on the back of the pack. Hold the flame up to the top of the Bunsen burner where gas is emitted until a flame appears. Adjust the size of the flame using the gas line knob or the stopcock as needed.
The Bunsen burner uses the combustion of methane (also called natural gas) and oxygen according to Equation 1 to produce heat. If enough oxygen is available, roughly two moles of oxygen for each mole of methane, then complete combustion will occur and maximum heat (flame) will be produced.
Feb 22, 2023 · Strike back Bunsen burner It is designed to be used in places where there is a risk of gas leaks. Has a special feature that prevents the flame from striking back into the burner tube.

Mar 22, 2018 · If the air port is open and the gas flow is too low then the gas will start to burn down the tube and you'll get a "strike back" where the flame is either (1) blown out or (2) burns at the jet. If the gas flow is too great you can blow the burning region off contact with the upper tube.
