The parts of a Bunsen burner has collar,base.air hole and barrel. Collar : Adjust size of air hole Base: Support Bunsen Burner Air hole: Allow air to enter air hole Barrel:To ensure the flame is adjusted to a suitable position
The four(4) flame types of Bunsen burner is depending on flow through the throat holes (holes on the side of the Bunsen burner -- not to be confused with the needle valve for gas flow adjustment). 1) air hole closed (Safety flame used for when not in use or lighting). 2) air hole slightly open. 3) air hole half open. 4) air hole almost fully open (this is the roaring blue flame).
The parts of a Bunsen burner include: the barrel, gas hose, base, collar, air hole and gas flow valve. The Bunsen burner is a small adjustable gas burner that is mainly used in scientific laboratories.
To heat chemicals or substances in science lab for experiment. There is an air hole in the Bunsen burner where you can screw loose to have open air hole that is the blue flame which is hotter. When there is a close air hole then the flame would be orange in color which is not as hot compared to the blue flame.
collar for turning to close and open the air hole air hole for allowing oxygen to mix with the gas barrel for the gas to go up gas hose for allowing gas into the Bunsen burner i hope i understood the question right?
The function that covers the air hole in a Bunsen burner is the collar.

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.
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
if you are using a busun burner,then you can turn the 'air hole' to cover the gap and then turn it to full it will seem to disappear and then reappear.
The is an 'Air hole' at the bottom of the burner. This air hole has a slip collar , which can be twisted/turned/rotated in order to control the air flow. When the collar is turned such that the air hole is closed, then you have a 'slack' yellow flame. When the air hole is fully open , you have a 'roaring' pale blue flame. The temparture is controlled by the air hole too!!! . With the yellow flame is at its coolest, and with pale blue flame is at its hottest. However, you need a special heat resistant thermometer to insert in to the flame to read the actual temperature.
Striking back of a burner means that the burner's air hole is not open all the way. This causes an air shortage that needs to reach the gas. This results in too much air buildup through it, which causes the flame to burst out of the air hole.

how will you prevent a burner from striking back
Yes,it can .But it might take longer time to heat
To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.
