I've been searching for this for days, but cannot find it. What is the weight of a typical boiler on a WW2 US Navy ship?
Example: Fletcher Class DD had a total weight (displacement) 2100 to 2500 tons and carried 4 boilers built by Babcock and Wilcox, each of which produced 600 psi steam from operating temps of 850 F. But it does not mention weight, and I can't find any model number to look up either.
Babcock and Wilcox seems to be the dominant boiler company for USN ships. The Baltimore Class Cruisers had them, as did the USS Essex CV-9. If everything from DDs to Carriers used them then I think it's safe to say they were dominant.
So it's strange I can't find any model numbers and details. Decent sites I've found but don't say weights:
https://kbismarck.org/forum/viewtopic.php?t=8969 (This thread looking for the same thing, very depressing someone mentions two books about boilers that do not give weights. I also looked thru history.navy.mil to no avail.)
Those last two actually have a lot of line drawings, however I cannot find a list of weights anywhere in them, not even the more generic weights of lightship or deadweight.
That list of sites is by no means exhaustive of my search efforts, just the best ones found so far.
Why do I want to know the weight of a boiler? Well because they look pretty huge and heavy. If those things total up to hundreds of tons...I mean imagine how much weapons and fuel you can't have due to that extra weight. A 5 inch shell and its powder seems to be about 40 kg. If you had an extra 100 tons, that represents 2,500 more rounds of ammo you could carry. Same story with fuel, and other weapons and ammo. So this sort of thing is important for logistics.
