Bunsen burner is commonly used in laboratory equipment. It is named by inventor Robert Bunsen. The basic functions of Bunsen burners in the laboratory are heating, sterilizing, and burning. It produces a single open flame. There are six main Bunsen burner parts such as barrel, collar, air hole, air inlet, air valve, and bracket.
A typical Bunsen burner diagram is shown below:
Bunsen burner parts and functions
Bunsen burner is one of the important components of laboratory equipment, which is mainly used to heat various materials in the laboratory. Is located below the support frame, and there is a glass test tube on the support frame. The test tube is filled with other fluids for heating purposes. The gas used is mixed with a continuous flame. It has six main parts as follows:
- Gas flow valve
- Gas Intake Tube
Barrel (part of Bunsen burner)
Its tube is about 5 inches long. The main function of the barrel is that it has an air inlet that mixes air and gas. It is a metal tube located under the burner. The barrel has a smiling hole (air inlet) that opens downwards allowing air to enter the barrel.
When natural gas and air bypass air ingress and are sucked into the barrel, the mixture of gas and air will ignite through the top of the barrel, allowing to function normally.
Collar (parts of Bunsen burner)
The main function of the collar is to control the amount of air entering the barrel. It is located around the air hole at the bottom of the barrel. The collar works on the screw mechanism. The clockwise rotation of the collar increases air intake, while the counterclockwise rotation decreases.
It controls or restricts the supply of gas to the barrel.
Typically, the base provides support for the Bunsen burner. It usually appears as a hexagon (hexagon). It can be supported; it is a large part of the Bunsen burner.
The gas in the Bunsen burner is responsible for allowing it to enter the barrel through the valve collar. It is usually installed on the basis of a burner or screw. The airflow valve and barrel can be adjusted equally clockwise and counterclockwise.
Air holes allow Benson to enter the burner to obtain a mixture of air and gas or any other liquid fuel and air (such as petroleum).
Rubber tubes are used to transfer gas to the Benson burner.
The air inlet is where the gas enters the burner. This helps to expand the airflow valve. The main function of the air inlet is to control the leakage of gas through the trachea.
Functions of Bunsen Burner
In 1852, Robert Bunsen invented the Benson burner for the first time. This equipment is commonly used in scientific laboratories to heat a variety of materials and liquids under a continuous flow of natural gas or liquefied petroleum. It is usually placed under a support frame consisting of a beaker or test tube, which is filled with liquid.
When adding fuel, the first thing is that air will enter the barrel when the air hole opens. If the air holes close, a yellow wave-like flame will appear, which is called the coldest flame glow.
The air reacts with the incoming gas and produces a blue or non-luminous flame at a rate of one-third. When using a Bunsen burner, a non-luminous flame is always the first choice because it is the fastest flame and the brightest flame is the easiest to control.
No soot or smoke is produced in the flame. Bunsen burners are easy to use, so you should always be alert to laboratory safety rules and regulations to avoid your danger. In any dangerous or accidental situation, students should be quickly referred to as emergency treatment.
What is the hottest part of the flame on the Bunsen burner?
The Bunsen burner produces two types of flames, namely the luminous flame and the non-luminous flame. The glowing flame is the coldest part of the flame, while the non-luminous flame is the hottest part of the flame.
