Liquefied petroleum gas (LPG), also referred to as simply propane or butane are flammable mixtures of hydrocarbon gases, used as fuel in heating and cooking equipment and produce a blue flame. Camphor gives a flame, which is widely used in worship. Charcoal, does not vaporise and so, does not produce a flame. Charcoal is a solid fuel. This is the reason that it can't vaporious on heating. Coal or charcoal does not produce flame when burnt because it does not vapourizes, only those substances which vapourizes on burning produce flame like wax , natural gas.
