Making Steam the Navy Way

I do realize some of these posts have a narrow appeal – I ran across this and since this blog is a pretty big deal to 5 or 6 people out there AND 2 of you cook water for a living – here you go . . .

A while back, a friend of mine asked me what happens if there is a loss of steam pressure in an operating naval boiler. Short answer: The generating tubes melt. The boiler could blow up.

Long answer: Take a look at the schematic of a 1200psi naval plant. look at the boiler on the upper left corner. See the circle in the boiler labelled “SD” and one labelled “WD” and the two curved lines between them? Those are the steam drum and the water drum.

Naval boilers do not have circulation pumps. There is a steam drum at the top, the water level is kept at the half-full mark. The water drum is at the bottom, it’s also called the mud drum. The two drums are connected by the steam generating tubes and the downcomers. The generating tubes are in the firebox, the downcomers run between the boiler and the air casing. (There are also screenwall tubes, which protect the sides and rear wall of the boiler casing. Those tubes also generate steam, but not a significant amount.)

For those that are interested ( and we know who YOU are ) follow this link to TARGET: Babies in Open – Fire when Ready – This will take you the post – the home page is HERE . . .

The above is a read me first post for THIS POST . . .

The site is one of those I try to get to at least every two weeks – narrow appeal but good stuff . . .
