Note the lag time between when the Bridge orders a bell change and when the engine responds. A good Conning Officer has a feel for how long it takes for the ship to respond to an engine order.

If you're one of the Covidiots who believe that COVID-19 is "just the flu",
that the 2020 election was stolen, or
especially if you supported the 1/6/21 insurrection,
leave now.

Because It's Friday
Down in the engine room of a steamship.

COMMENT MODERATION IS IN EFFECT UFN. This means that if you are an insulting dick, nobody will ever see it.
And there is a lot more going on in the fireroom and the engineroom then is shown in this clip.
ReplyDeleteIn the old days of manual boiler tending, the water level, the amount of fuel oil and the amount of air all changed in response to a throttle change.
And in the US Navy steam turbine enginerooms, there was only 20 percent of the power available to go astern than there was to go ahead.
And if you tried to take steam to fast from the firerooms, you could drag boilers off the line.
And this leave aside the technical discussion of superheaters with separately fired furnaces.
Even in steam turbine destroyers, there were still reciprocating pumps.
Immediately reminded me of Fritz Lang's Metropolis...just missing the lights.
