Amazing...
As I understand and please correct me if I'm wrong. Typically in a large water tube boiler (from previous photos this station is using water tube as apposed to fire tube) the coal is fed into a crusher to crush the coal to pebble size lumps before being fed to the fire at the bottom (as seen at the bottom of the square shoots. Water tube boilers are in effect a big brick room with steal tubes filled with water running up the sides of the room and all connect to the bottom of a big drum at the top. Another set of tubes run from the top of that drum and run across the top of that room to super heat the steam from the drum. That drum is usually half filled with water. Water tube boilers are more efficient than fire tube ones you see on steam trains.
