Would be great to have something like this fired by anthracite 8-)

I would think most any stoker boiler could match that.

A Garn type would be possible but you would need to grind the coal to dust being minus thirty mesh being the size of ground flour making it a pulverized coal boiler and you deliver it with a huge paddle blower and use oil to ignite it to start it each time and the amount of heat it would deliver would be huge and un manageable if the heat can be maintained to ignite it after starting the initial burn as the coal dust would have to be delivered at a constant flow rate to provide fuel to burn with the available combustion air.

Look up pulverized coal boilers on a search engine and you will see how they work.

The issue I have with mine is that it will kick out over 145,000 BTU on oil and even more on coal which is too large and I get overshoots at times and I wait until late November to fire it. It would be different if I had cast iron radiators but I have baseboard which I absolutely hate but I have to live with it.

I would and will advise anyone looking into a keystoker boiler to stick to the next lower model being the KAA-2 but understand the 3 grate flat bed stoker firebed for the KAA-2, KAA-4 and KAA-4-1 are the same size.

Ideally keystoker should also list in thier literature the simple fact that they can sell you a smaller stoker to put in the KAA-2 and KAA-4 and 4-1 and be honest about it they told me that I could buy a new stove stoker to put in my KAA-4-1 from them for a little less than $900.00 with the adapter plate to mount it to replace the 3 grate stoker that came with the KAA-4-1.


my thoughts anyway.

No point in hand firing when it needs electric for the fans. Do it right and get a Van Wert 4000.

The Garn Units are specifically made for "batch burns" wherein the system uses secondary combustion using two sets of fire tubes in a water bath andin using the second set of burner tubes they pull all the available BTU's from the batch burn using clean dry season firewood that is 24 inches long per stick. as a result the exhaust gas temperature is barely noticeable and any remaining embers are blown into a barrel under the flue pipe with a 45 degree flue pipe directed into the barrel that has sand in it.

x2. Not literally "any", but EFM 520 and up, Keystoker KB-8 and up, AA/AHS 260, etc.

Also a little disappointed because I thought the link was to one of those extraterrestrial dudes with the lizard heads from Star Trek. Oh well. :roll:

BAH!!!, The Hurst HPD coal miser with its traveling grate system can be hand fed with soft coal, wood waste and other biomass fuel.
Their traveling grate system carries the heavy bottom ash to the end of the traveling grate where it is dumped into a fly ash cart to be disposed of and it has a wall of fire brick to create an afterburner before the flue gasses enter its 3 sets of fire tubes before the flue gasses and fly ash enter the electrostatic precipitator to be collected by a fly ash auger before the scrubbed flue gasses are blown out the stack. The only thing it lacks is a flue gas water scrubber after the electrostatic precipitator to make it more user friendly.

When it comes to burning anthracite efficiently, it is very hard to beat what the Ol Timers have already designed, tested and put into production.
With that "water cooled exhaust" the Garn seems to be specifically designed to through heat out and capture it in the exhaust. You wouldn't be able to maintain a chimney draft needed for anthracite.
Maybe the "Gorn" could scare it into burning anthracite?
