AF Refurb or Scrapout...to Be Determined...

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Off topic, but I would never get rid of my cast iron radiators. Best heat you can get. Plus they look cool. Matt

Ya that is a cow we had several years ago. 1/4 Brown Swiss, 3/4 Jersey. What she may have lacked in production she made up for in attitude and stubbornness. :lol: Nah she really wasn't that bad. Just a house cow, raised a few calves and pigs with what we didn't use. What few Shorthorns I've worked with have been remarkably calm and easygoing, are yours this way or did I just luck out?

Been too busy with other stuff and haven't had a chance to do much more with the furnace since last posting, other than just cleaning it up more. Hopefully this week/weekend. Bonus is I found a small Lincoln mig for real short money that should make this job lots easier. Should be interesting...

On Shorthorns (That I have owned!) most all are Remarkable calm. That is why I raise them.

have had plenty of others but always had good luck with that breed.

Get to work on the Refurb. the cold is coming! 8-) 8-)

Let's just say, I am no gas weldor! Either couldn't get it hot enough to do anything, or was melting holes (#2 and #4 tip, old Oxweld W200 aircraft torch.) I'll get that process eventually but I don't think on this project, unless on the internal baffle (thicker). Cutting torch works well but need a smaller tip for it also, great for bolts and heavier stuff but too hot for the sheetmetal patches. Works, but the cut edges are too hot--melt back together behind the cut sometimes. Technique of course has its part in this as well :oops:

Thank goodness for MIG, that has been going way better. Pictures later. I've been grinding to clean metal, welding cracks, grinding down welds (ha, grinding OUT welds too!) and welding patches over same. One spot is very very thin, may have a "fun time" dealing with that section. Will post a few pics of that as well, pre-repair-attempt.

Pictures from this past Saturday's work. Haven't finished with the side seams yet, they look pretty awful at the moment as they are way over-filled; need to grind down (a LOT!!!) and put patches over, so it won't just crack thru the weld. Any pointers would be welcome.

Top patch:

Side welds (they are ugly, and I just noticed there's a gap in one of 'em, still, oops!):

Not looking too great. Got the thing apart further today and the lower reaches of the secondary heat exchanger are badly eroded. The outer surfaces are one thing, but inside the 'donut hole' as it were they are also eroded; doubt it will be easy or even possible to effectively repair this area. Too hard to reach in with the welder and doubt if there's enough metal left to stick anything to anyhow. I may try it, just to see, but am keeping an eye peeled for a better alternative. Some mild destructive testing with a 1 pound hammer, lightly wielded:

The primary heat exchanger baffle was eaten away as previously noted. It was warped badly enough that it would not come out through the stoker mounting plate holes. I cut it in half to remove it. It did not cut like normal steel, nor did it look normal: crystallised? I don't know what changes happened to it but the edges act like normal mild steel. Weird.

Unless something changes this project is all done. Too much risk of another hole(s) popping up during the heating season, and cost of repairs is approaching the cost of a good used stove/furnace. If anyone would like parts, pieces, or the entire carcass PM me.

Looks like it was far worse than it appeared in the first pictures. The stoker may still have some useable parts.
