I've been studying the Titanic, which had triple-expansion steam
engines exhausting into a turbine, designed for better efficiency than
previous (faster) vessels like Lusitania. The ship consumed 650 long
tons of coal per day to generate 50,000 HP at 75 RPM, or about 1.2 lbs
of coal per HP-hr. I haven't found how much of that went to
electricity and refrigeration.

Each hand-shoveled furnace needed 400 - 500 lbs an hour.

One of the surviving stokers was standing 2 feet from the aft end of
the hull crack, right under the forward funnel.

Another factoid about the Titanic: 13x the weight of the fully loaded
Titanic is buried every year in phone books at landfills.
