Good Morning!
I picked up a Tarm Excel 2200 Gasification Wood Boiler this week, from the tag it appears to have been made in 2001:
It is a Wood/Oil (or Wood Propane) boiler, on the wood side it heats the wood till it smoulders, then burns the gas/smoke at around 2000F below the firebox:
Picture from: Tarm Furnace | Excel 2000/2200 | Wood and Coal Furnace Parts
A demonstration video of the next size down (the Excel 2000):
The previous owner was using it and it sprung a pinhole leak in the back of the firebox, they ran it (with the pinhole) for about a month on oil until they could get someone in to replace it (they put in a wall mount condensing gas boiler to replace it).
Not sure how often it got cleaned out as it had a lot of ash buildup/creosote buildup inside, here is a picture shortly after I started:
And where I stopped for the night. Can someone confirm that the corners (circled in red) should be square? It looks like they should be, but I don't want to break something if they are supposed to be angled. It appears that there is a bunch of creosote or ash built up there which is a solid lump:
IIRC, the leak is somewhere around where the yellow circle is, if not its a few inches below that:
I pulled out about 10 gallons of ashes out and that was just the easy to get stuff:
The flame tunnel from somewhere in the clean out process:
And how I left it for the night, 200w fan heater in there to warm things up and hopefully dry things out (sitting on a metal plate to keep it dry), not sure if the refractory absorbed any water (or if it can), but I figure that if everything is dry, it will be easier to work with than if its wet:
The plan is to get it cleaned out, then tape my needle scaler to a stick and pound the back wall until its clean.
Once its clean, I will look for pitting, pressurize the "tank" and spray soapy water on the back wall to see if there are any other leaks.
If there are not, it will get welded up and installed in the basement this spring/summer.
If there are, it will get sent to the scrapyard.
