You puffer guys have fun. Of course your stomachs at a pH of around 2 or something and the microbes are just food unless they think you are food.

I guess if you blow down religiously and try to add some stuff like T.S.P. to keep the boiler somewhere near alkaline then you will only need a new boiler ever few years (grin).

Didn't one of those rivers back east catch fire some years ago? There's a whole new idea. Feed water as fuel.

Yes, burning river. The cuyahoga. It's close by. Doing much better nowdays.

It would have been perfect for a naptha launch. :lol:

"If I can drink it, I call it good enough for my boiler to drink. "

I don't understand the logic here? For example, you can drink pure sea water, it won't quench your thirst, but no harm to the human body, yet that is about the worst thing you can use as feedwater into a boiler.

In the Glencannon stories he carefully avoided drinking plain water on the basis that it would rust his inner workings. Duggans Dew of Kirkintilloch taken straight!

Well there was a emoticon wink there - I was just inserting my own view of it. I readily admit to my insanity, if that's the question.

Maybe I meant 'would' instead of 'can' .

Until a recent (last 10 years) EPA thing the Point Chautauqua Water company water source was a 100 feet section of pipe out into the lake.
I'd drink Chipewa or Chautauqua water.

But It's a mute point. I have two mesh strainers for particles, and Teryln LSB treatment takes care of the water conditioning. And no, my launch is never going into an sort of a salty water. That's a limitation for sure. Nyitra I is a fresh water fish.

I am way off topic - I'll give you that.

Clothes line. It takes a while to install, but it works. Inexpensive too.

Once you install the economizer, you'll see a marked improvement in plant performance. The hotwell temp will be irrelevant. Due to your automatic water tending, the boiler is seeing little and often on the feedwater, the economizer works really well like that.

For small pipes I use felt sheets which I get on ebay as a modelling material. Wrap a couple of layers round the pipe and "borrow" some cotton thread to hold it in position. Then use some pre plastered bandage (again from ebay as before) and now the messy bit: using wet hands smooth the bandage over the felt, when dry paint with emulsion paint, you may need 3 or 4 coats - colour to choice! This is good as it will follow the pipe bends easily. From memory I think the felt comes in 2 inch wide strips. Hope this helps. I have used it on 1/2" copper pipes.

Floating plastic balls would insulate the water. BUT, if the surface of the balls is wet because of sloshing around, you have multiplied greatly the surface area of the fluid and thus the oxygenation rate of the water.
