Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Coal has many other uses. It is used as a source of heat for manufacturing processes. For example, bricks and cement are produced in kilns heated by the combustion of a jet of powdered coal. Coal is also used as a power source for factories. There it is used to heat steam, and the steam is used to drive mechanical devices.

Steam—chapter_combustion - gutenberg

Combustibles —The principal combustibles in coal and other fuels are carbon, hydrogen and sulphur, occurring in varying proportions and combinations.. Carbon is by far the most abundant as is indicated in the chapters on fuels. Hydrogen in a free state occurs in small quantities in some fuels, but is usually found in combination with carbon, in the form of hydrocarbons.
