Coal Delivery
Coal is delivered via a railroad by 100-car trains, each carrying 10,000 tons of coal. At the plant, an automated unloading trestle empties the train in about 30 minutes and conveyor belts move the coal to the storage pile or the storage bunkers inside the plant. The bunkers hold a 14-hour reserve; the coal pile target inventory is a 32-day supply.
Coal is coarsely crushed at the mine then crushed again at the plant as it travels to the storage bunkers inside the boiler house. A pulverizer below each bunker grinds the coal to a fine powder that is mixed with air and blown into the boiler through a network of pipes. With both units at full load, Plant Wansley burns about 14,000 tons of coal every 24 hours. Annual consumption averages four to five million tons.

““The room’s very hot, with all this crowd,” the Professor said to Sylvie. “I wonder why they don’t put some lumps of ice in the grate? You fill it with lumps of coal in the winter, you know, and you sit round it and enjoy the warmth. How jolly it would be to fill it now with lumps of ice, and sit round it and enjoy the coolth!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“There was no speculation so promising, or at the same time so praisworthy, as the United Metropolitan Improved Hot Muffin and Crumpet Baking and Punctual Delivery Company.”
