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.
A tall cylindrical burner with a flame on top, an oxygen valve and a gas supply tube.
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).
Bunsen burners are a fire hazard and should not be left unattended. However, accidents can occur even when the burner is off. Check the tubing connecting the gas line to the burner to be certain there are no cracks and it is secure. If the tubing is dislodged and the gas line valve is not off, gas will fill the room creating a potential explosion situation. This has happened. There are safer alternatives to the classic Bunsen burner. A Flame Boy or a Touch-o-matic burner eliminates the issue of a constant flame. A bacticinerator can be used to sterilize plating loops. There are also glass bead sterilizers that may be used.
Less air enters the tube and the flame burns less fierce and appears more like the yellowish flame on a candle.
The needle valve or flow valve controls the flow of gas into the Bunsen Burner.

There will be a valve at the bottom of the Bunsen burner. Using a rubber tubing connect the valve to the regulator of the LPG cylinder.

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 change the flame on a Bunsen burner you need only to open or close the air valve to change the combustion reaction.
The valve on a Bunsen burner is able to control the gas flow by opening an closing an armature. The smaller the armature, the less gas flows and vice versa.
The needle valve is used to control the amount of gas flowing to the burner. The air valve controls the amount of air.

A Bunsen burner flame can both roar and burn quietly, by allowing more oxygen to reach the flame by opening a valve it will roar, by closing the valve the flame will flicker
A Bunsen burner flame is hottest when the air valve hole is open.
The temperature of a Bunsen burner is regulated by gas and airflow. The gas is controlled by a flow valve and the air is controlled by a screw mechanism on the collar. Different type of nozzles can control the flame's shape. The Bunsen burner was invented in 1855 by Robert Wilhelm Bunsen (1811-1899).
