The Bunsen burner has a controllable air supply and a unceasing gasoline jet , therefore when the air supply is reduced ; a highly visible , yellow / orange ‘ safe flaming ’ is give rise . For heating work , the air recess is opened and the burner produces a much hotter blue fire . Therefore , the two flames produced by a Bunsen burner can be categorise as :
Luminous Flame
Luminous flame is a type fire produced by a Bunsen burner when the air - jam ( part of the Bunsen burner ) is opened . The fire is by and large chicken in color , large and wavy . It is fully visible since it bring on a bright glowing fire .
When the air hole of the Bunsen burner is unopen , very picayune air enters the barrel of the burner , thus the petrol only mixes with surrounding air at the point of burning at the top of the burner . In this case , the flame will be yellow , gravid , unfirm , promising and sooty due to uncompleted combustion .
Luminous flame are not used in experiments ( not skilful for laboratory operations ) because it is wavy and sooty in nature . Examples of lambent flamesinclude burn wood , candles , Olympic cauldron etc .
Luminous flame has three primary regions ( role ):
Facts About Luminous Flame
Non-luminous Flame
A non - luminous fire is the type of flame produced by the Bunsen burner when the atmosphere - cakehole is closed . The flame is generally blue in gloss , lowly , steady and can not be seen from far . It commonly burns with a roaring sound .
When the air - hollow of the Bunsen burner is amply opened , sufficient air enter the Bunsen burner barrel and mixes well with the ember gas , hence , the burning of the petrol is much ready and complete . The flaming is modest and hot . Due to the absence of ashen - red-hot carbon paper , no light appear .
Due to limitless supply of air travel , there is usually all over burning of C and thus non - luminous flaming are hot and do not produce smut . For this reasonableness , they are most preferably used in experiments ( laboratory operations).Examples of non - aglow flamesinclude fire of a Bunsen burner when the air - hole is closed , acetylene torches etc .
Non - lucent flaming has four independent regions ( region ):

Uses of Flames
Flames are used for different purposes . Some uses of the flame admit the following :
