Looks awesome
One thing i noticed in the last pic was just 3 stays in one row. Stays is what I'm calling the metal rods between inner and outer boiler metal.The Econoburn i have has at least twice as many just in the upper burn chamber.I remember seeing a video comparing the Econoburn to another boiler and that was one of the features that was pointed out.

When I added secondary air tubes to my previous boiler I used mild steel. They could not take the heat at all, lasted about one cord before turning into bananas. I sourced some 304SS tubing, drilled it and they lasted much better. Just FYI.

Also, depending on how your doors hold up, you can use Varmiculite sheets for some insulation.

Were the tubes "free", not in firebrick? I could see that warping. I plan on firebricking the tube in place, should keep it from warping I think.
 
Binfordw, what is your background? This isn't a weekend warrior project...

I work maintenance at a local factory- but at home I run a tiny business making airgun targets. I made my plasma table 4-5 years ago to be able to cut my own parts, and that's about it. I do some occasional plasma jobs for local shops, but its often sporadic.

Made your own table? Can you give me some details on what motors/drives and software you are using? Perhaps a link to point me in the right direction. Thanks! BTW your workmanship is awesome.

Thanks Buzz Saw, I sent you a PM. (Or a conversation, I assume its the same thing here)
 
I scored a large amount of free used firebrick and fiberboard from work a few days ago. I've spent the past few days making a HUGE mess, cutting used bricks back into uniform shapes.

I set up an old chop saw to make the cutting easy.

(broken image removed)

Its a big mess, but I like this brick better anyway, plus, I can return the unused brick I bought.

Hi binfordw
I was working on my Ecocnoburn last night getting ready to replace the nozzle.I took note that there were 3 rows of stays on each side of the boiler just in the firebox,and 2 rows on the back wall.The back wall is shorter because of the flue.I know there are additional rows in the lower chamber as well.
Just an observation

I appreciate the suggestion, I would prefer more supports, and I may still add 3 more per side.

I'd be interested in the same information. I also work factory maintenance. Buying a plasma table is for sissies.
 
So now I have my pad poured, and about half of my tubing buried. I finished the exhaust stack, and got it welded into place. I also welded in 2 in's and 2 out's, 1" fittings for my pumps and returns. The pump fittings have tubes that run through the water jacket towards the front, and are braced internally.

While I wont fully make the end of month deadline, it still feels like a victory. The pad really needs a week to cure anyway I'd say, before sitting 2500+ lbs on it. I plan to move this beast 2 weeks from now, and get it sit on the pad. Then hopefully same weekend get the enclosure built and insulated. That gives me 2 weeks to finish all the loose ends, which I feel pretty good about.

Won't be long now!

Easier pumping and more heat moving capacity? That's without knowing your heatloads and how far away they are though.

Thats why I felt 1" was suitable, my house is small, 1700 sq/ft, and 85 ft from boiler. Shop is 36x45 and right at boiler, but main heat will be 2 back rooms that are about 16x16' each.

Regardless, I already have 1" pex tubing, so its a done deal. 1.25" would have put me in the poor house from the prices I saw anyway. Seems the majority of people use 1", even for much much larger spaces, so surely its suitable for what I'm doing.
 
1" at 85 ft seems like it'd be quite the pressure drop. Gotta remember 1" pex is close to 3/4" I.d.

New Updates to the build thread

I'm within 2 weeks of moving it to the pad now. Spent some time tonight reworking the latches to a simpler design (which I really like), and testing the final seams at the top for leaks.

All thats left now really is a few more bricks/mortar in the secondary, cut the floor plates, cut/weld the top cover on the water jacket, add a fill port and the water level float, and thats about it.

Read about the build on the other site. Any clue how many hours you have in this beast?

Love the workmanship. As more time goes into the boiler it is slowly becoming a work of art l!
