@ObsidianUrbex The third picture is pretty well self-explanatory--I'll only add that somewhere down that dual conveyor line is a device measuring how much coal is delivered per minute so that the boiler is fed in a steady manner. In pic 1 I saw 2 boilers; in the third I see two belts, and in the 4th pic I see two flashtanks, so my bet is that this location had only two boilers, total.
