Why do coal power stations not directly use combustion to turn …
This has been tried, although the turbines did not power electric generators but train locomotives. Gas turbine trains fueled by coal and by heavy fuel oil have been tried, but both had problems with soot buildup and turbine blade erosion from soot and ash particles. Running a gas turbine on any fuel that does not burn cleanly but that has solid …

Coal & electricity
Steam coal, also known as thermal coal, is used in power stations to generate electricity. First coal is milled to a fine powder, which increases the surface area and allows it to burn more quickly. In pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.
