The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant boilers produce steam at a high pressure and temperature. The steam is then piped to a turbine. The high pressure steam impinges and expands across a number of sets of blades in the turbine. The impulse and the thrust created rotates the turbine.
