Not 100% sure I need this ... but "need" is such a subjective term.

I am just testing the water

.. and seeing if anyone out there has a vertical boiler that is not critical to their list of projects...

If you have one - Lets PM about it..I don't really need an engine, but am willing to discuss if you have a set..

Thanks

Thanks Rob...Yep -I had those in my watch list- though the second seems the most likely candidate_ I watch The US, UK and Canada pretty regularly.

I just thought I would see if anybody here had one that didn't pan out for them.... The old " members -safer" mantra rings in my head.

I have been pretty lucky with my Ebay and Craigslist purchases... you never know when the luck runs out...

Thanks for the reply - I hope that traction project of yours is going well!!

Mo, if you like putting your own finishing touches on a boiler (like cladding), you could think about getting one from Maccsteam, http://www.maccsteam.com/

I've got one in the big boat, and it's a work of art....surprisingly affordable for what you get. Not cheap. but not megabucks either, and serious quality.

yeh i forgot about it being a kit.

Ahh, I do not need to decide right now... I have projects aplenty thats for sure...And diameter and other measurements will tell me what I need to do - or at least whittle down the options ..

Thanks Rob and Moose...

I agree that my soldering skills would have to leap froward at warp speed to do a multi tube boiler

So other than this would need a round ceramic burner and many other things .. is Burnac Crap or a item worth consideration --???I could dress her up if the basic boiler is a sound design..

Mo, Burnac are nice.....that boiler would only drive a small engine though. Also, some of them have steel boiler backplates - worth asking the seller. If it's copper or brass, fine - if it's steel, make like a hockeyplayer and get the puck outta there....

Thanks Moose,, so the engine I am thinking of is this one...but I also have an extra SEL

It may not be powerful enough and I need to opt for a twin... but .....?

Ah, I see.

Is this for the new boat? In that case, both the SEL and the one in the picture will have enough power to drive it. The one in the picture is double acting, right? In that case it will be good to have someting that can chuck out a bit of steam. The problem with a vertical "pot" boiler is that , compared to a horizontal, they have a small heating surface, even with a centre flue.

That's why the boiler in my big boat has six tubes running through it, to effectively maximize the heating area....the trick is not only to be able to raise pressure, but then also sustain it, in other words, generate steam quickly enough.

I'm a newcomer to these rather more serious boilers, so somebody will correct me if I'm getting it wrong. One thing to bear in mind though that these things operate at higher pressure - soft soldering is not an option, and a boiler failure would have more unpleasant consequences than a basic pot boiler would.

All this explains the elevated price these things come at....they're not a bit of brass tube with a couple of caps, there's rather more to it than that.....

Aye the one in the picture is double acting Moose-i have the twin version

Certainly with the larger engines the problem is actually maintaining steam for a period of time. And as Moose says this brings the cost up...

Far more work making a 'tubeplate' as opposed to a plain end cap etc etc

If you use that engine with a meths fired boiler it will use the steam quicker than the boiler will produce it.
