This much I know.
That duct-looking thing at the top left is where the pulverised coal comes in, I think (the single thing you’re guaranteed to hear about the coal used in a coal-fired power station is that “it’s ground as fine as face powder”).
The big rectangular thing to the right of the duct is the boiler.
Near the extreme right of the picture is the turbine (the three cylinders).
And the bits inbetween? Um… Pipes, mostly.
