stoker cut top and water tank welded on

PostBy: wnycoalier On: Mon Apr 28, 2014 11:06 pm

Saw a fun local craigslist for a stoker stove with the top cut off and a water tank welded on top. Three bungs welded on it. An in, out and pressure relief.
Anyone seen this done? I'm really assuming there is a thread in this, but I can't make the right keywords to bring it up.

WOW and Mike usually is first is line to speak of my 'TERSE" ANSWERS LOL someone must ont have been nice you you last night Mike

So seriously - wny = you can build what every you want with the skills and tools you have
your mileage may vary
in the long run purchasing a proven design will benefit you more

Can you post a link to this "creation"? Just curious, probably not a great idea but worth a look.

The CL posting just said "coal boiler" $1200 I called the guy and that's the description. Seems a reasonable mod that falls under "why not?"

As to the replies about go "buy a boiler" . Neither helpful, nor responsive to my question.

Sorry if you found my post to be nonresponsive. With all of the good used boilers around that can be had for comparatively short $, I can't imagine why it would be tempting to take on somebody's amateur attempt to make one. What is the heat exchange surface area between the combustion chamber and the water tank? It seems unlikely that it would compare to the efficiency of a professionally designed boiler. Is the water tank even made of materials that can survive the rigors of direct exposure to coal burning?

Real coal boilers generally reflect a lot of engineering and metallurgical expertise, not to mention decades of experience, none of which should be sold short. Obviously it's your money; do what you like.

The CORRECT answer that you wanted to hear : Buy the $1200 piece of junk that the wannabe inventor is selling because he found his "invention" is .... junk.Be sure to report back to us when the temps dip below 20* next winter,so we all can make a cheap boiler instead of supporting the companies who make them & just think that they have invested time & money into testing & all the other work involved in building an approved & safe unit. No need to get upset with us giving our opinion,its your choice,don't ask, just go get it !

I guess a Bottom Line for me to you would be: It's your money and time,do as you feel. This past Winter was the Litmus Test for anything Experimental. Hell of a Bad Time to find a Fail. The Metallurgy and Ability to Transfer Heat Issues hold a lot of Water-No Pun intended. If you're a Tinkerer and the Mad Scientist Type,then something like this would probably be right up your alley. If you need a Heat System to carry you all the way through Winter,and provide your Domestic Hot Water,then I would say don't even think about it. 1,200 bucks could really go a long way towards re-habbing a used,new to you,proven Boiler Design that will give you what you need. There's a True starting point. What exactly do you need? What would you hope to achieve for next Winter. You've started this Journey at the right time. Maybe we could help you kick around a few thoughts on this. A House type,size and existing Heating System Package of Info will help us to help You. What type of Chimney do you have? How big is your Flue? Basic Stuff fer sure,but it's a great Ground Zero to put you on the road to what you would want...... :up:

The description of the boiler sounds exactly like mine! :o

Mine works FANTASTIC - better than I could have ever dreamed. Does everything it's supposed to - kept this drafty dump warm during the coldest winter in decades, on LESS coal than my handfired, and only had one outfire due to my soft head. The fire has remained lit with no power for almost 4 hours during a windy day!! I LOVE this boiler. If that thing is anything like mine, I'd grab it!

Mine is run by an Alaska paddle feed:

Woah-smitty way to take this post from hopeless netflamefest into a hot topic!
I notice you have through tubes, whereas this creation seems to be just a square box welded to the top . As for all these "cheap boilers" believe me i'm looking. I haven't found a single stoker boiler. Only thing I've seen is a $6000 new keystoker model. Which if you define as cheap- costs more than my last 5 cars put together.

hey Smitty!!

That vessel looks very much like the TARM 4.0 that was sold by tarm to many others - many times it was produced with a certification stamp welded to the vessel - but I didn't see one in the pics you posted

nice simple vertical tube boiler - not fussy what fire is under it - pellets - corn - chunk wood - coal :)

The efficiency of a vertical tube appliance such as that can be greatly enhanced with something [ called a turbulator ] to disturb the hi temp flue gas, as it travels the vertical tube. In your application sort of a pain as the smoke pipe is off the top - if you take the time this summer and build a slightly larger upper smoke chamber and port the flue gas off one side of the box - build a removable top and hang a length of transport size chain in each tube about 3/4 the way down. l little tab at on end is ll it takes to keep it suspended -

yes you will have to pull and punch the tubes but your fuel usage will go down and your appliance will operate better

Image

I ran one just like it
This is the turbulator I used

I left other pics of my vertical fire tube boiler based on the same design here http://www.iburncorn.com/ but the pages are gone now

So yours is not a simple box welded on top of a stove :P its a good solid designed applaince.

wnycoalier,

I don't know how far you want to travel but there is a AHS S130 coal gun just north of Baltimore. The listing says it's 7 years old and asking $2000. It's been on there for a month now. I don't think anyone in the area knows what it is! I wish someone would buy it so I don't have too!

WOW great info Sting - thanks!! I have those exact turbulators in my unit - it came with them already inside. Can't see them from the bottom - they stop about 1.5 inches from view. There is a cert. plate welded to the water vessel - I'll get a pic of it here ...

Been VERY happy with this unit. Jim D. was a smart man - he had been in the heating field for many decades. I had no doubt it would work .. but I never realized it could work this good! 8-) I'll be forever grateful to him. Just the description the OP gave is how I thought of my boiler - that wasn't meant to sound like it was a BAD or poorly designed boiler - that couldn't be further from the truth. :) I do like the fact that if I could no longer burn coal in this thing, I could burn just about anything in it: used oil, tires, etc... :lol: and still stay warm.


Here's a pic with the top off.

Image

I couldn't go any bigger with that cover if I wanted to - the pipe is already inches away from my floor joists ... :o :D Far from an ideal situation, but I had no choice with the location of my chimney, and the myriad of things in my way. This time of year I have to vac those tubes and bump the turbulators every 5 days, or else CO starts coming out of the hopper ....
