Are we referring to the tubing bends in the superheater headers, screen-wall headers or something else?

Where the heck is cRusty, running errands?

I belive three. Two using BFW and the other potable. If I had to guess I would say that the triple would be BFW and the double for potable.

After this weekend thats a good question. Kinnda felt like "s" bends.

Sorry had to re edit.

Where the heck is cRusty, running errands?

Did he get hurt again? I noticed you mentioned ankle.

There are boilers on gas turbine ships, they're called Waste Heat boilers and they use the exhaust heat from the ship's service gas turbine generator (SSGTG) as the heat source to make "hotel" steam and low pressure steam for the evaporators, among other things. I still have the burn mark on my forearm from a 3/4" valve and bonnet from a steam drain off #3 waste heat boiler off the John R. Young in 1991. For many years I could read the name of the valve manufacture and engraved serial number in reverse on my forearm.

Nah, just needling him again. He's attending his wife's healing foot. I guess if I bug him enough, he'll send Vito or Carlos over and I'll have an accident and break my foot/ankle.

According to my copy of the New Jersey Propulsion Operating Guide (S9BBO-B5-POG-010/BB62), there are SIX evaporators in the upper level of the forward Diesel Generator Room.

Also each engine room at the lower level has one main condenser and two auxiliary condensers for a total of four mains and eight auxiliaries.

I have a copy of the BB manning list around here somewhere. But for obvious reasons I don't feel like digging for it. Just remember, whatever it takes to man the engine spaces IN ONE SHIFT must be multiplied by at least 4 or preferably 5 to cover all three shifts plus relief time of the regular crews. So if it takes 7 men to man one boiler, 35 must be accomodated.

And I've been running errands for my wife who is having some bad reactions to her pain medications after her operation. I'll put her to bed and less than 30 minutes later (after I try to go to sleep) she jumps up from a nightmare. Or she will call me and ask if I've locked the front and back doors. Or she will ask when she's going to go home from the hospital. Then she will ask me to make sure both front and back are locked again. Then she cries because she has forgotten what happened to Saturday (when she was acting normal).

IMPERIAL JAPANESE NAVY MYSTERIES

I was surprised that the Nagato survived a nuclear blast relatively unscathed (USN report stated "It is recommended that the construction of boilers and uptakes of the Nagato be studied with a view to...incorporating some of their features into the design of our vessels in order to make them more resistant to blast pressure.").

And it would have survived the second, underwater blast if it wasn't so contaminated that a crew couldn't board to do basic damage control.

Is it 6 evaporators or 6 shells making 2 triple effect evaps? Don't tell me I'm actually going to have to dig through some of my books for research...

Each HP/LP turbine has a main condenser under it and each SSTG has an auxiliary condenser under it.

Hey old friend. I'm a STRUCTURAL engineer, not a mechanical. I can just tell you what the simplistic diagrams in the POG show. As it is, on our inspection of the Iowa last year, I had to make a mechanical engineer out of an electronics engineer to look for missing parts in the machinery spaces. He learns real well as the next inspection I had the NAVSEA program manager out here confirming his findings.

Next time we do an inspection of Iowa, I'm taking you along as my co-driver.

Like I wrote earlier, my memory is shot when it comes to the evaps on the Misery and Jersey. I can't remember working on them, rather I spent time insulating the a/c plants. Maybe dreadnought can do an inspection on the Jersey to see if the evaps are marked "1st Stage, 2nd Stage, and 3rd Stage or whatever. The Proteus AS19 had 2 triple effect evaps in the main machinery space and the old DD's (Fletchers, Gearings, Sumners etc.) had single stage evaps.

GAAAGH! You had to mention the Proteus, didn't you?

In Greek, Proteus was a sea god that could change shapes. In medicine the Proteus bacteria is often mistaken to be the Typhoid bacteria.

That ship fit both descriptions.

Her original hull was riveted.

Her jumbozied midships (for stowing Polaris missiles) was welded.

Her sh*t doesn't run uphill so I had to design a special transfer sump for it.

Her older aluminum bulkheads were installed with hot stainless steel rivets to steel deck coamings.

Her later aluminum bulkheads were secured to steel coamings with Huck bolts.

Her last aluminum deckhouse (that I personally designed) is secured with bi-metallic joint (aka Deta-Couple that is aluminum on one side and steel on the other).

She is sitting alongside the Iowa in Siusun Bay awaiting "dispostion". I would like to suggest that her disposition consist of two Mk 48 torpedos bottom side and two Harpoons topside.

The "Old Pro" was a pig sty even after it finished overhaul in 1980. I still have a mint orange and black "AS 19" hat.

Nagato was a strong ship for her build. There were many characteristics they gleened from the tests to incorporate into our own builds.

One thing I always found peculiar was the fact that they allow people to dive on these ships at Bikini however New York, Nevada & Pennsylvania among other ships were rated too hot to handle and therefore have never been dived and shown like so many others.

I dont believe for a moment that the USN didnt plot their locations of scuttling nor have more information related to the conditions prior to and or after the tests.

Pal,
I will relate these finding as soon as I can get one particular man on the weekends. Given his rotation it may be a week or so. But I will keep up with it.
Ive been wanting to detail it for some time (powertrain and related) since It is not available for general viewing. Perhaps write an article if I can get everything nailed down and photos to match and this particular man to sign off on it. I have all kinds of pictures that are of spaces NEVER seen or read about in most books I have checked on the Iowas. But I have to make sure to give proper credit and so fourth and secure the pics for copyright before proceeding.
Thanks.

So you're going to put a name to the pump/machinery that you have pictures of and then list it's function? Sounds too ambitious, too much writing, too boring.....
