Perhaps I'm wrong, but this strikes me as an easy one. Why is the base so large? So it's harder to knock over when people are moving about in the lab.
It prevents the burner from falling over.

What controls air flow in a Bunsen-burner?
the air valve at the base of the burner
Why is the base of a Bunsen burner usually broad and heavy?
This is to reduce the chances of the burner accidentally tipping over. Knocking over a lit Bunsen burner could obviously have very bad results.
What are the 5 main parts of a Bunsen burner?
Air hole, collar, barrel, base, burner tubing
What colour flame in the Bunsen burner is the noisiest?
Blue - since it draws air up the tube of the burner from the hole at the base. The noise is the sound of air being pulled into the tube by the heat of the flame above.
What is the air inlet of Bunsen burner?
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.

Where is a Bunsen burner not hot?
The base. Usually, the base of a bunsen burner is covered in an insulator material, so you have somewhere to pick it up without burning your fingers :)

Bunsen burner blue flame?
The blue flame of the Bunsen burner is when it is hottest. The yellow flame is the safety flame. you should always start the burner on the safety flame which is produced when the holes on its base are closed.
How do you obtain a flame from a Bunsen burner?
You turn the air admittance ring at the base of the Bunsen burner until it is fully open. this allows the hottest flame to be produced and has a blue colour
