This is because coal does not have complete combustion whereas candle or kerosene burns completely

Why do observe a flame initially when wood or coal burns and glow later on?
The flame is produced by gasses coming out of the fresh wood/coal. Once the gasses are exhausted one is left with just the carbon and this does not gassify as it combusts and therefore just glows.
What is the texture of coal?
The texture of coal is a 'hard, shiny, black rock. However, the 'hardness' and the 'shininess' can vary depending on the impurities present. However, it is always black. The texture of coal can vary from Peat, )A black wet earth) coal in its early stages of formation. (Burns/combusts with a lot of smoke) Then Lignite ; a soft black rock, with no wetness. ( burns/combusts with less smoke). Then coal as described above ( burns/combusts with a hot bright flame, dependent on the amount of oxygen draught present). Finally Anthracite ; hard and shiny ( Sometimes known as 'Black Diamond'( burns/combusts with a hot bright bluish flame, dependent on the amount of oxygen draught present).,
What is kerosene oil?
Kerosene is a thin clear liquid formed from hydrocarbons obtained from fractional distillation of petroleum. The process of distilling petroleum into kerosene was first written about in the 9th Century in Persia. By the 1700's it was known as a byproduct of making coal gas and coal tar, but it burned with a smoky flame and was not for use indoors. In 1848 a Canadian discovered a new process and made a fuel for lamp oil which burned bright and clear
What type of coal burns the most effeciently?
The type of coal that burns the most efficiently is anthracite coal.
When coal is burned the ash weighs less than the coal when magnesium burns the ash weighs more than magnesium?
That is true. Coal is composed mostly of carbon, and when it burns it turns into carbon dioxide, which is a gas. The ash is just a minor residue of the non-carbon part of the coal. Whereas, magnesium when it burns turns into a solid material, magnesium oxide; it gains oxygen from the air and therefore increases in weight.

Why does burning of candle produce flames and burning of coal cannot?
First of all we will have to know that what is a flame made up of,a flame is made at a point where fuel and oxygen combine,so in case of both candle and coal there is a fuel ie.wax in candle and coal is itself a fuel.................but if we just think till this much then even coal should produce flame but it doesn't go like this ,actually we are missing something ie. hydrogen(the main component in every flame producing substance).........if hydrogen is not there flame will not be produced .So wax has hydrogen atoms whereas coal doesn't because coal has been burnt before and hydrogen has been used.................that is why hydrogen containing waxy candle produces flames whereas already burnt coal just gives heat not flames. Hope this helps.

What gas comes from under the north sea and burns with a blue flame?
Methane is a gas that comes from under the North Sea and burns with a blue flame. Methane gas is highly flammable and dangerous. This gas is responsible for most of the explosions that occur in the coal mining industry.
