sooty flame refers to the flame produces after burning, which shows incomplete combustion, i.e, insufficient supply of oxygen.
A "sooty flame" indicates that incomplete combustion is taking place. The most likely cause for incomplete combustion is lack of oxygen.
Sooty Flames= Flames that producing Blackish coloured smoke
A lack of oxygen in the combustion process causes a sooty yellow flame and produce excess carbon monoxide. Excessive CO can be immediately dangerous to life in an enclosed space.
For the same reason anything else burns with a sooty flame--not enough oxygen. What happens is, the outside of the flame gets all the air it wants, and the little oxygen that makes it through isn't enough to properly combust the fuel. If you mix air with the fuel before you burn it, as is done in a carburetor or a welding torch, you don't get a sooty flame.
hydrocarbons, in general.
I Believe It Is The Roaring But I Am Not Sure. When We Put A Test Tube Into The Roaring Flame, I Think It Turns That Part Black. It May Be The Medium Flame.
Black carbon soot is deposited on the porcelain
Non-luminous flame should be used for heating in the because the flame is steady and produce little or no soot. Non-luminous flame is very hot thus, it is recommen- dable to use for laboratory purposes. Luminous flame is unsteady while non-lumi- nous flame is steady. Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
luminous
When a hydrocarbon is burnt in the presenceof oxygen it gives heat, light, and carbon dioxide gas producing a sooty or non-sooty flame

yes
It is less hotter than non luminous flame. Used for lighting only It produces soot that makes apparatus sooty

the fire of the non-luminous flame willl haeve a great spark to the flame
