As you are aware, the flammable gas goes into a Bunsen Burner through the rubber tube. To burn the gas, you need oxygen, in air. By controlling the amont of air available, you vary the colour, temperature and ferocity of the flame.
Te air inlet is a hole at the base of the tower. It has a collar around it which can be rotated to vary the amont of air available.
If the collar is closed, no extra air is added and the only available oxygen comes from the air around the flame. With so little oxygen, the gas doesn't burn to completion and carbon soot is produced. This makes the flame yellow and clearly visible (for safety sake) but not as hot.
If the collar is fully open, air is pulled in through the inlet and mixed with the gas before burning. This provdes more oxygen, a hotter flame and more complete combustion to carbon dioxide and water. This flame is blue with a roaring sound and can be almost invisible to the casual abserver.
In practice, always light a Bunsen Burner with the collar closed so that you can see the yellow flame but open the collar to give ablue flame when heating. This avoids coating everything in soot. When you have finished, close the collar again to leave the flame clearly visible and yellow for everyone to see.

What controls air flow in a Bunsen-burner?
the air valve at the base of the burner
What is the function air hole of a Bunsen burner?
The air hole in a Bunsen Burner allows air to mix with the gas prior to burning so that the flame can be adjusted as desired.
Where does Bunsen burner's energy come from?
A Bunsen burner is a flame that makes a devise that combines flammable gas with air, named after Robert Bunsen, the German chemist who invented an improved Bunsen burner in 1855. A Bunsen burner is used in laboratories.
What affects the intensity of the combustion reaction of a Bunsen burner?
The intensity of the combustion reaction of a Bunsen Burner is affected by the air supply, which is regulated by how far the air hole is open.
Who was the Bunsen burner named after?
The Bunsen burner was named after one of its inventors, Robert Bunsen.
Air inlets of a Bunsen burner?
The air inlet is on the burner tube; the flow is regulated with a rotating barrel.
Advantages of Bunsen burner?
Because of the adjustable air inlet you can get flames of various temperatures.
Where does gas enter the Bunsen burner?
Gas enters the bottom of the Bunsen burner, where it travels up to mix with air before moving up the stem to meet the flame.
What is the function of the Gas inlet of the Bunsen burner?
The inlet valve at the bottom is used to draw oxygen in from the environment so that the flame burns more efficiant and hotter. If closed the flame will be an orange colour and will leave a sooty deposit due to the gas not oxidizeing compleately.
What part the hose play in the operation of the Bunsen burner?
The hose go to inlet of gas fuel in the burner.
Different kinds of burner?
Three types of laboratory burners are the Tirrill Burner, Bunsen Burner, and the Meker Burner. The Tirrill and Meker Burner have air and gas adjustments while the Bunsen Burner has only an air adjustment. Hope that helps.
What controls air flow in a Bunsen-burner?
the air valve at the base of the burner
How was the Bunsen burner invented?
Robert Bunsen was a German chemist, who is credited along with his partner, Peter Desaga, with the invention of the Bunsen Burner. In 1877, Bunsen along with Gustav Kirchhoff, was the recipient of the very first Davy Award. He was one of the most admired scientists of the time.
What is the function air hole of a Bunsen burner?
The air hole in a Bunsen Burner allows air to mix with the gas prior to burning so that the flame can be adjusted as desired.
What is the difference between a Fisher burner and a Bunsen burner?
the deffirence between terrill burner & bunsen burner is that terrill burner has a greater flexibility in the adjustment of the air-gas mixture which bunsen burner cannot .
Where does Bunsen burner's energy come from?
A Bunsen burner is a flame that makes a devise that combines flammable gas with air, named after Robert Bunsen, the German chemist who invented an improved Bunsen burner in 1855. A Bunsen burner is used in laboratories.
What covers air hole in a burner?
The function that covers the air hole in a Bunsen burner is the collar.
