[AT] Fuel Oil vs. Diesel Fuel

Sun May 8 07:36:41 PDT 2011

I wonder how much did they have to change the engines/turbines to convert?  Reason I ask is when they were re-activating them in the 80's, they took tons and tons of equipment off the North Carolina.  I got to go on a "behind the scenes tour" a couple years ago (NC list members it's called "Hidden Battleship" and it's well worth the price.  Guides take you into spaces on the ship that haven't been touched since 1947) and they showed us one of the engine rooms where the big turbine had been removed.  Didn't say which ship it went to but it was one of the Iowa BB's.  My point is, the fact they got one off the NC might give a clue to whether or not they had been converted.

One of the tourguides actually demonstrated how a boiler was lit.  Pretty fascinating. I forget how fast but it was amazing how fast they could get a dead cold boiler online.
