The principal materials used for fuel are petroleum and coal. Ordinary hard coal is called anthracite coal, and the soft, lumpy kind that crumbles very easily is called bituminous coal. All fuels are composed of carbon, or compounds of carbon and hydrogen, called hydrocarbons, combined with such impurities as ash, sulphur, nitrogen, etc.
