The History of the Steam-Generating Boiler and

For example, Babcock amp; Wilcox developed their version of the tube and tile boiler starting with their type FF, which was a two-drum boiler capable of producing up to 54,000 pounds per hour of steam. For higher capacities they offered the FH, FJ, FL, and the FP, with the largest design and highest steam capacity (100,000 pounds per hour).

How to Destroy a Boiler -- Part 1

The boiler is actually an oversized distillery in that the water that enters the boiler is vaporized to steam, leaving the solids behind. Depending on the amount of solids in the water, or hardness, the residue is sometimes visible when a pot containing water is boiled until all water is vaporized.
