For example methanol (race car fuel) (1 carbon 4 hydrogens 1 oxygen) burns with an almost invisible flame and acetylene (2 carbons 2 hydrogens (cutting torch without the oxygen turned on) burns with a bright yellow flame with clumps of soot raining down.
As a result, the flame emits yellow light. This type of flame is, therefore, called luminous flame. For example, the flame of a kerosene lamp. In kerosene lamp the fuel does not undergo complete combustion due to the insufficient supply of oxygen. Now let us study structure of a paraffin wax candle. flame is a hot, luminous gas or vapor. Gaseous substances burn with a flame. Those solid and liquid fuels which can vaporize on being heated also burn with a flame. Depending on the amount of oxygen available for burning the flames can be of two types: 1  Non-luminous or blue flame.
