Answer 1

1.  Base :  A metallic circular (conical) wide base allows the burner supports at its center, the barrel to stand vertically.

2. Nozzle:  A nozzle is fitted to the bench with a rubber tube coming out of it.  Through this tube gas comes enters the burner.

3. Barrel :  A cylindrical metallic tube fitted in the base.  The barrel allows uniform flow of gas through it to the opening on top. There is a hole in the lower part of the barrel for air to enter it.  There are two flames that come out from the top opening of the barrel.

     There is a collar fitted on the barrel that contains a hole for air to enter from the atmosphere.  The desired flame type can be obtained by adjusting the collar.  
4. regulator :  The regulator is useful in turning on or off the gas supply. Also, the amount of gas flowing into the barrel can be adjusted.  Thus the desired type of flame can be obtained.
