Picture of Burning Coals

For those of you who have watched “The Lord of the Rings” movies (hopefully most of you have), doesn’t this picture remind you of the scenes of the forging and destruction of the One Ring deep within Mount Doom?

Unlike paper and wood, coal does not burst into flames when it is burning. However this does not mean that coal does not produce much energy. For equal masses of coal and paper, coal produces many times more energy, but the release of energy is also much slower. This means that a small amount of coal can be used to produced a large amount of heat over a long period of time – perfect for a barbecue.
