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.

The device works by mixing gas and air in a controlled manner and then igniting it, resulting in a clean and efficient flame. The Bunsen burner was invented by Robert Bunsen in 1855.
In 1852, Robert Bunsen was hired by the University of Heidelberg and promised a new laboratory building. The city of Heidelberg was installing coal-gas street lighting, so the university laid gas lines to Bunsen’s new lab. Bunsen wanted to improve existing laboratory burner lamps by making them more economical, simple, and able to reach high temper...
The Bunsen Burner consists of several parts, each with its own function. These parts include: 1. Base:The base is a heavy metal stand that provides support and stability to the Bunsen burner. It also helps to protect the laboratory surface from the heat of the flame. 2. Gas inlet:This is the point where the gas supply, such as natural gas or propan...
The Bunsen burner flame is a hot, blue flame that is perfect for heating, sterilizing, and combustion purposes. It is a non-luminous flame, which means that it does not produce soot. The flame consists of three parts: the inner cone, the outer cone, and the non-luminous zone. The inner cone is the hottest part of the flame, reaching temperatures of...
Here are some of the specific functions of the Bunsen burner: 1. Heating liquids:The Bunsen burner can be used to heat liquids for a variety of purposes, such as dissolving chemicals, conducting chemical reactions, and preparing samples for analysis. 2. Sterilizing laboratory equipment:The Bunsen burner can be used to sterilize laboratory equipment...

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.
