Bunsen Burners



Non-luminous flame

  •  when the air hole of the Bunsen Burner is open 
  • when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced." 
  • its color is transparent or blue 
  • Blue flames are its hottest flames 

Luminous flame

  •  is produced when the air hole is closed
  • if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygen 
  • A luminous flame has an outer of orange color and an inner of blue. 
  • Luminous flames emits more light than non-luminous flames.
