Burning Coal - an overview | ScienceDirect Topics

Coal Gasification. As an alternative to burning coal in air to generate heat and raise steam to power a steam turbine, it is possible to convert coal into a combustible gas. This can then be burned in a gas turbine power plant or, depending upon the composition of the gas, used to provide fuel for a fuel cell.
