Parts of the Bunsen burner

• A yellow flame means there isn't enough oxygen
• The flame is blue when it has enough oxygen
• The blue part is where most of the combustion takes place.
• The orange part is where the fuel is being burned.
• The flame is green if there is too much water vapour
• The flame is orange if there is not enough air
• The flame is red if there is no air at all
• The flame is purple if there is too much fuel
• The flame is white if there is too little fuel
• The flame is red if there is not enough air supply
• The outer cone is where the gas is cooled by air as it leaves the burner.
• The blue part of the flame is called the luminous zone, which contains carbon dioxide (CO2) and water vapour (H2O).
• The yellow part of the flame is called the non-luminous zone, which contains unburned hydrogen (H2)
• The Bunsen Burner is made up of 3 parts.

  1. Barrel
  2. Collar
  3. The gas jet
• Barrel - This is where gas and air meets for combustion
• Collar- It is a small disk at the bottom of the barrel that you adjust to control the amount of air entering the barrel.

  It has a air hole to allow entry of air into the barrel.
• Bunsen Burners are used to heat substances or liquids. They are also used to melt metals and glassware.
• The gas jet - The gas jet - Allows the gas

  to enter the barrel from a tube connected to the fuel source and

  mixed with air from the air hole before combustion.
