+1 I'd love to do that with my Arcoliner, but it has a wet bottom, no room for a stoker.

Depending upon the clearances, you might be able to fit one that mounts through the ash door.

I was wondering about how I'd get the ashes out... Have to use the tape measure and figure out how much room I have. I'd hate to stick the bugger in and not have a way to get the ashes out.

Use an ash removal system or open the bottom of the boiler to empty into an enclosed ash collection area (e.g., a masonry pedestal or pit w/ash door).

Wet bottom cast iron here, the foundry didn't leave me alot of room.

Hand Fed Coal Boiler: Biasi 3wood 7

Post by dperg » Thu. Nov. 26, 2015 11:10 am

The conversion kit is rated for 35kw and is made for a viadrus U26 7 section that is comparable to my biasi .
The controller or steering that I bought with it is a Tech St-37 (see Attached) and controls the feeder,fan,overheat protection of the hopper and has options for a tstat and can control a pump. All electrical is 220volt. I burn Primarily pee that I fill my toter bins with but it also burns rice and could also burn wood pellets. I did have to make my own ash pan to fit.

Did you just hook it up to a double pole breaker or were there any conversion issues?

The floor is wet? Or just the walls of the ash area?

I'll take this to a pm so I don't drift Callum's thread anymore than I have.

Ever since Unhippy started this thread I have been wondering what the heck "steam mini tube" is. In my cast iron radiator research on Youtube I found a guy that has built a mini tube system. Here is the system overview video.



The way that I stumbled across this was he posted a video of a small cast iron radiator that he got for free. He hooked it into his mini tube system on a whim. The results are surprising! He shot some video with a thermal camera and if I read the time stamp right, it took 10 seconds to heat the whole radiator to 200 degrees!!!



Amazing!

Unhippy, I hope things are going well on your project. It's mid-summer down there now. No pressing need for heat for a few months.

Nice timing Don....the first pieces of steel were welded today......the frame for the base that the boiler to sit on :D

boiler design is sorted out and the steel plate is waiting to be picked up, most control parts that I think I will need are in the spare room awaiting the time they are needed.....a few parts are still on the way

i would have started building about 3 weeks ago but I had some vehicle problems that needed sorted out before anything else

that guy that did those videos is the one that got me interested in the steam minitube concept.......i found his website by accident

i'm not sure in that video if it 10 seconds or 10 minutes....i suspect more towards 10 minutes as according to his post on "The Wall" forum his boiler is severely down-fired to take advantage of the lack of pickup factor needed with a minitube compared to a 'normal' steam system.....in one post he mentions that he is running 46'000 BTU INPUT into whatever efficiency his boiler is......and heating a radiator even that size in just 10 seconds would take a rather large amount of steam in a big hurry.

Which if he is down-fired that much, he wouldn't have unless he could shut off the rest of the system and use the whole boilers output to feed that one radiator........and he doesn't seem like the kind of prat to pull a stunt like that

I'm glad things are moving along with the boiler project, I was getting a little worried!

So, Jerry Gill is the one that got you interested in mini tube steam. His videos of steam systems are very interesting if you are curious about steam heat in general.

First pieces of plate where cut for the boiler today.......i'm using 5mm COR-TEN steel......mainly because its higher tensile than mild steel plate....and hopefully slightly more rust resistance on the surfaces in contact with the hot gases

i got all the internal surfaces cut out of one sheet of steel that was 2525mmx1265mm..... with a little left over as I based all my layout when designing on 2400mmx1200mm sheets (standard 8'x4' size).....
damned if I know why they make the cor-ten in that size sheet....it doesn't line up with any of the old imperial sizes like most sheets still do.... and if they are going to do metric sizes why not 2500x1250mm :?:

very rough sketch of what i'm building
steam boiler.png
.PNG | 10.4KB | steam boiler.png
There is 12 inches between the crown of the firebox and the top of the boiler......water 4" deep on the crown plate...primary & secondary LWCO's at 3"& 2.5" above crown plate

the black line in the steam chest is a separator baffle 3" down from the top of the boiler to prevent carry over of water with the steam......at the max steaming rate and lowest pressure i'm going to be running at, it should have the steam passing over it at 4 fps......more than slow enough to drop any water out of suspension, the baffle is tilted slightly to allow any water that does drop out to run back into the boiler

not shown are the 1/2" stay bars with 3/4" pipe compression tubes over them that are going into it at 6" spacing's

I will hopefully remember to take my camera down to work tomorrow

Looks like a good gas path layout. 3 triangular tubes, 1 downward wet baffle and 2 pointed upward wet baffles. Very similar to my Gentleman Janitor. The Gentleman Janitor was the triangular tubes at a slight up angle side to side and opposite each other and the downward wet baffle is also set at an angle.

I thought that you might recognise some of it :D
