Power Station

What happens in a coal power station?

I want a scientific answer as to what happens in a coal power station, about the diffrent energy info, and what powers what.

A lot happens - it is a complete course in thermodynamics to give a full answer, but, here goes:
Assumption - it is a modern 500MW set in UK.
The coal is fed in to mills, which grind the coal into a fine dust similar in size to talc. This is blown onto the boiler, where it immediately ignites, transferring heat to the water and steam in the boiler tubes. The hot products of combustion are sucked out of the boiler, through the precipitators, which remove the pf (pulverised fuel) dust from the gases, and the gases are then treated and released to atmosphere. The pf dust is collected in hoppers, and is transported to land-fill, or used in building.
The water, which has been heated in the boiler, is then divided into water and steam in the boiler drum, and the water is returned to the boiler wall tubes for more heating, and the steam, at very high pressure and temperature, is then fed into a turbine which is turned at 50 cycles per second. The generator is directly coupled to the turbine, and produces electricity by attempting to accelerate the grid system, to which it is electrically (magnetically) attached. The phase difference produces real and reactive power.
The steam travels through the high pressure turbine and back to the boiler for reheating. It is then returned to the intermediate presure turbine, and then piped directly to the low pressure turbine(s). All three sections produce the same amount of turning force, and are all on a common shaft.
Underneath the low pressure turbines is the condenser, which converts the steam (now at low temperature, and under near vacuum conditions), back into water, known as condensate or feed water. The condensers are fed cold water to convert the steam back into condensate (water), and the cooling water is then itself usually cooled in cooling towers, which give off water vapour.
The condensate is then fed back to the boiler via the feed-heating train, consisting of low pressure feed heaters, de-aerator, boiler feed pump and high pressure heaters, all of which are heated by steam bled from the turbines.
The whole process is about 40% efficient, and the losses are approximately half up the chimney, and half converting the steam into condensate.
