A Bunsen Burner is generally used in laboratory Apparatus. It is named by the inventor Robert bunsen the basic role of a bunsen burner in the laboratory is heating, sterilization, and also combustion. That produces a single open gas flame. There are 6 significant bunsen burner components i.e, barrel, a collar, air holes, gas intake, gas valve, and also stand.

Let’s acquire Started…!

Parts the Bunsen Burner and also Their Functions

it is just one of the necessary parts that the laboratory equipment and is greatly used because that heating various materials in the laboratory. It is set beneath a support stand that holds a glass test tube various other liquid-containing product for heating functions using a mixture of gasses through a constant flame. It has actually six major parts which room as follows:

BarrelCollarGas flow ValveGas input TubeBaseStand

Barrel (Parts that Bunsen Burner)

it is about 5 inches lengthy tube. The main role of the barrel is that it has air intake openings that mix air and also gas together. The is a metal tube the lies on the base of the burner. A smile dimension of feet (air intakes) is current on the barrel that opens up at the bottom permitting air into the barrel.

when herbal gas and also air attract into the barrel bypassing the air intake opening, the gas and also air mixture ignites through the top end of the barrel to make it functional.


the major function that the collar is to control the lot of air entering the barrel. The is present approximately the air feet at the bottom end of the barrel. The collar functions on the screw mechanism. A clockwise turn of collar rises the wait intake amount if the anticlockwise rotation decreases.

Gas Spot

it controls or boundaries the supply of gas to the barrel.


typically, A base gives support come the bunsen burner. The is often current as 6 sides ( Hexagonal) shape. Gift supportable, the is a vast and heavy component of the bunsen burner.

Gas Valve

The gas Valve in the bunsen burner is responsible because that letting gas into the barrel with the collar. That is frequently attached come the basic of the burner or screw. The gas circulation valve and also barrel both can be adjusted likewise as clockwise and anti-clockwise manners.

Air Holes

the waiting holes allow air to enter the burner because that a mixture the air and also gas or any type of other fluid fuel with air e.g, petroleum.

Rubber tubing

Rubber pipe are used to transport the gas right into a bunsen burner.

Gas Inlet

A gas inlet is a allude where gas start the burner. It help to extend the gas flow valve. The significant function of the gas inlet to manage the leakage the gas v a gas pipe.

Functions that Bunsen Burner

in 1852, Robert Bunsen invents the bunsen burner very first time. This an equipment is frequently used in the scientific laboratory under the consistent stream of organic gas or liquified petroleum come heat various kinds of materials and also liquids. It often set under the supportive was standing which holds a beaker or check tube complete of liquids.

connecting through a source of fuel, the an initial thing is done that air enters into the barrel on opened the wait holes. If friend close the wait hole, a yellow wavy fire will appear called luminous of coolest flame.

the wait reacts through the start gas and produces a blue or non-luminous fire at the one-third ratio. The non-luminous flame is always preferred while making use of the burner due to the fact that it is the sexy flame and also easiest to control over the luminous flame.

this flame likewise does not produces soot or smoke. Making use of a burner is a firey job-related so one should always be careful and also should adopt the laboratory security rules and regulations to avoid any kind that hazards. In any type of case of any kind of danger or accident, college student should conveniently be described as the very first aid treatment.

What is the hottest component of a flame on a Bunsen burner?

it to produce two species of flames i.e. Luminous flame and also non-luminous flame. Luminous flame is the coolest part of the fire while the non-luminous flame is the sexy part.

FAQ’s (Frequently inquiry Questions)

What is a Bunsen burner offered for?

the bunsen burner is vital laboratory apparatus that is used to create a constant flame to heat different substances and solutions by mix gas through air in a controlled fashion. 

What room the parts of a Bunsen burner?

there room six parts of the bunsen burner i.e., Barrel, Collar, Gas circulation Valve, Gas entry Tube, Base and Stand.

Is Bunsen burner dangerous?

Bunsen burners are thought about extremely dangerous because of the existence of fire hazards. The chances for accidents to take place increases since it produces develop an open up flame by burning at a high temperature.

What component of the Bunsen burner combustion happens?

as the reminder of bunsen burner fire from the inside is considered as sexty part. As soon as the quantity of fuel gas Is boosted the needle valve, the size of the fire will likewise increase.

How does a Bunsen burner work?

step1: mix the air and natural gas. 

Step 2: ignite the mixture the air and gas indigenous the peak of the tube. 

Step3: Bunsen burner will certainly ignite and also start heating the substance placed on the height of the flame. 

Step 4: gas flow will stop by closeup of the door the gas valve. 

What is the use of barrel in Bunsen burner?

the barrel existing at bottom or basic of burner to screw it. Because that the relocation of different instruments, it is really important to tighten and also stable the burner. 

What are the 3 types of flame developed by the Bunsen burner?

three species of flame space as follows: yellow flame, Blue Flame, bright blue triangle fire in the center.
