Greg, What do you do with the big pile of ash? I'm think of using mine for soil cement. While the anthracite ash is not as good as bituminous ash for this purpose it looks like it might work. For those of you not fimiliar with soil cement it's a way of making a poor strengh concrete. Spread the ashes on the earth, spread portland cement, rototill it all together. The cement absorbs moisture from the earth and hardens. Anyone have experience doing this? The quality of the final hardened product is highly dependend on local soil conditions and the mix percentages. It must be topped with real concrete or asphalt for long life.

I will dump the ash in the ruts and pot-holes in my farm roads. It seems to set-up pretty hard.

I may try the cement mixing, but I have some fairly heavy equipment on my roads, and I fear they will just crumble the weaker cement.

Take care, Greg L

Merry Christmas !

I used to cringe when family came over for Thanksgiving or Chirstmas because I could just hear the propane burner in the house's boiler roaring to keep the house at 68*. This year I may have to TURN DOWN the thermostats 'cause the house may be too warm!! WHAT A LAUGH!


We're in the process of that right now. With the coal stoker going, the oven on baking and three people in the house (my mom is visiting for the holidays), not to mention the 40 degree weather, I'm opening windows and airing out the house. The stoker hasn't done more than idle all day! I'm so happy! :) :lol:

Normally, I'm the guy going around and turning down the thermostat -- just imagining the oil burner firing up and cringing at the dollars going down the drain. 'Tis the season and 'tis a much better season with coal!

Will clinkers break down with exposure to or a long soaking in water?

Im looking at sifting options and while im going to collect the ash im wondering if the clinkers will break down into more ash/dust.

I have a Crown Royal outdoor wood/coal boiler. I tried wood and went thru about 3 cord in less than a month so I changed over to nut coal. It seems to be doing a lot better on coal (about 45#, 2 times a day). My question is I'm getting a lot of clinkers. I read where maybe it's to much air coming up from the grates and also from poking it. My boiler has forced air coming in thru the ash pan as well as air over top. If I cut back on the air will that lessen the clinkers? Thanks

I've heard of quite a few folks opening their draft flap an 1/8-1/4 " to keep a steady draft going.With the forced draft & huge coal bed the tendency is for the coal fire to get too hot,then cools too much,then heats too much & then on & on & on. With that big a bed of coal it would be far better if the stove would have a constant natural draft instead of the intermittent BLAST draft which causes the coal bed to "over fire" & then cool & repeat. Most all stokers have a very limited amount of coal to burn at any given time. The ash is either falling off the end of the grate by the weight of the coal pushing or the underfed pots have the coal pushing up from below which causes the ashes to tumble off the edge much like a slowly boiling volcano action.

Yes I agree.. A coal fire in a hand fed seems to cooperate much better with a steady, consistent supply of combustion air adjusted for the heat output needed to satisfy the heat load.

Ok, thanks. Any thoughts on poking the fire and that making clinkers.

You can poke down thru, sure.. I actually use a heaving technique to lift the coal up so ash can fall in its place with my poker tool, then shake down again. This does a great job of clearing ash out of the coal bed. Its important not to stir the fuel bed in a manner that mixes the ash with the hot burning coal. It's the fusion of the ash thru high temperature that causes clinkers to form.

That may be part of what I did wrong. I poked it and brought clinkers to the top and kind of mixed it.
