I've been burning my December purchase of Mallard Contracting's pea coal. I still say it's the worst coal I've ever purchased. Very dirty with lots of fines. Lots and lots of white ash and many, many pea sized pieces of unburnt bone. It's also low BTU, no outgassing that makes the "dancing blue ladies". My combustion blower runs almost continuously to keep the boiler water up to temperature. This was never the case with other coal I've purchase. Thinking I might have an equipment problem and let the boiler idle, and did a through cleaning. Removed the AHS combustion fan, to see what was there. Boiler tubes were scaled but not too badly, there was some fly ash, a bit more than my previous experience but acceptable. The flue was another story. The AHS coalgun boiler design has a fly ash cyclone separator. This device causes some of the fly ash to fall to the ash pit. What doesn't is blown into the flue pipe. My flue pipe installation is such that flue gases have a high velocity path up to near the chimney thimble. There the abrupt change in gas velocity causes the fly ash to fall out. With the Mallard (new UAE) coal there was ten times the ash I've ever seen. The cyclone also discharges lots of fly ash to the ash pit. The bottom line is that this coal is not good coal to burn in a AHS boiler.

The creditability of the sellers is also in question. I called to complain and eventually talked to "Charlie" who identified himself as the manager. When I described my issues and asked if it was refuse coal, he said it was not. Said it was from the "Mammoth" vein. It may be, but in my opinion it was mined a century ago. To support my refuse coal belief there was a posting months ago about a coal truck crash on the east side of Mt. Carmel. Quoting from the newspaper article, "a private contractor hauling "culm" coal", "failed to make a left turn into a coal processing plant owned by Mallard Construction."

Charlie also promised to mail me a coal analysis report, still waiting, it's been weeks. My intent was to have my coal analyzed and compare. My recommendation would be to stay away or just buy a small amount to try. It's sad that a new company would use the reputation of the old UAE Harmony mine coal to sell their crap.

So Charlie, who said he was aware of this forum, post your coal analysis here for all to see. Post your PA mining permits that specify the location and veins you are mining. Anything else is just more B.S.

. It may be refuse coal because it is very dirty and lots of fines almost silt like I carefully shoveled about 300 pounds onto my concrete floor in basement to let thaw and dry a bit because my bin is outside and as I said before it was a frozen pile of coal by the time I got it home.. I could not believe the amount of silt that was in that 300 pound it's a lot I will take photos of it.. So just for the heck of it this morning I went out to bin and used a small wide hand shovel and scooped some coal off the top of pile to fill up a plaster buck shovel was full of same material what is known as silt dirt in my area.. I also will take photo of that over weekend.. But the stuff burns pretty good I get blue flame from my stove ash content is climbing a bit started around 10 12 % but climbing as I get into it.. So I have to agree with u that I don't think it's mammoth vein coal maybe what was laying around from it being mined before.. But I still am satisfied not thrilled but it burns.. I live in Schuylkill county in the heart of Anthracite and found the old UAE Harmony coal was best nothing better but that's history .. So I jump around from breaker to breaker trying out different coal and found its a roller coaster ride some years said source is good next it's not no one seems to be consistent that I found and some are never good it seems.. Would I suggest Mallards coal to others .. I would have to say no because most wouldn't be happy with all that silt mixed in with it for one.. For second sizing for rice coal should not be all over the place I said before mix of barley rice and buckwheat some stoves may have issues with the larger pieces may cause a failure .. It's a good source if u live close I guess because price is cheapest in a 60 mile radius and btu wise it's pretty good.. Can't speak for larger size coal being as bad but just my 2 cents on rice.. Now will I go back for more probably if needed but wouldn't be my first choice.. So my quest continues next up is Keystone Anthracite in Girardville hope it's not Reading Anthracite coal because they are awfully close to them said they deal with them but it's not there coal that they sell..

I live in Girardville and I echo your comments. The Mallard coal will burn but it's dirty. I would guess that they are not washing it properly to get all the "silt" as you call it. If the coal was properly washed there wouldn't be so many fines. But unless it causes a problem with your unit it burns pretty good but not good enough to make me go out of my way. They probably charge the lower price because they don't process it as much.

I tried the coal from Atlas and the rice is undersized. It didn't feed right and packed on the grate making a thick bed on the grates. That made it harder for the air to get through and it didn't burn as hot. I normally use Keystone Anthracite and when I burned through the buckets from Atlas I dumped in a bucket from Keystone. I could tell immediately when it hit the grates because I had to back the feed down two full turns. Keystone does not use Reading coal. Keystone cuts from two local strip mines and has it processed at South Tamaqua. It burns hot with a light redish ash.

I'm sticking with Keystone Anthracite. They are less than a couple minutes from my house and their coal is relatively clean and burns good.

Lately been buying coal from Tuscarora coal in Brocton I don't care for it but it's near me ,my father has been burning it for 20 years he likes it serves him well but he not picky if it makes fire he's happy.. It's cleaned well other than some wood in it lol..sized perfect btu wise not so great a lot of ash waste.. So I figured I give Keystone a try next... BTW: Do some coals produce more fly ash than others because that last 3/4 ton from Tuscarora really clogged up my stove and stove pipes with it in a hurry from all but spotless to stove going into safety mode in a month ..

So, I understand UAE Harmony is no longer the good red ash we used to get. This past summer I bought 6 tons of nut coal from them (white ash), I've been very happy with it. Burned great, no clinkers the ash content is greater than what it used to be but I seem to get good heat. The ash isn't red like we're used to but it isn't as white as some I've had from other places. Are you guys saying the quality has gone down from late last summer to now? I live in Centre County and am figuring to head there this Saturday to get load, should I go there or spend the extra travel time and go to Blashack off of 81.

A bought some rice coal from a local supplier that gets it from Blashack and it seems to be pretty nice too.

Maybe get nut coal from the old UAE Harmony and rice from Blashack because of the inconsistent size?

I use rice in the stoker I have in the garage and nut for my hand fired furnace in the house

I have been burning the Mallard Nut coal all winter. I am getting pretty good heat out of my Harman hand fired insert. However I am seeing much more ash content, and a lot of fines with this coal. My uncle is burning rice coal from Mallard and he too reports a lot of fines in his cleanout tray. I think I will try somewhere else for next season. Very friendly people at Mallard, but definitely not the UAE coal we were used to. :(

Never tried Direnzo coal but it sure is pricy @ 200.00 a ton of rice.. I heard a lot of good things about it but that price is a bit hard to swallow for me with so many other sources in and near the area..

It's not the same coal as the Old Harmany coal .. I just got a ton of rices week ago it is inconsistent in size lots of fines but it does burn nice my Harmon DVC 500 has no problem running it it's priced well at 170.00 off white ash I don't care about color as long as it's not at 18% like I had from others it seems to be around 13 % waste.. If u care about fines or dirty it's not for u.. As stated before Mallards coal wouldn't be my first choice but I would buy again if need be reason being there was a coal shortage last year or year before for whatever reason I have no clue but breakers were not selling to people if u didn't support them in past so I keep all my weight slips just in case I have to show it if there is a crunch again and I live in the region and had and know of many from area that were turned away at that time... So I don't put all my eggs in one basket for this reason ... The more I think about it we are splitting hairs here when it comes to coal all of us who bought the old UAE Harmony red ash coal are ruined we or at least me are trying to find another source to match that and I don't think it's going to happen :( sad but true...

Probably some coal gives off more fly ash than others, but the main cause may just be the amount of coal burned in that time period because of how consistently frigid the temps were. Previous years you may have only burned 2/3 or 3/4 the amount of coal as you did this year.

Picked up some DiRenzo rice coal two weeks ago at $180 per ton. Very happy with their coal. Buck $160 per ton.

Like the creature of habit and convenience I am I went back for another ton. I figure it will work nice when temps rise and I run my Mag for dehumidifying. Trying to get it dialed in today.3 attempts yesterday when it was still wet failed. Shale, fines/culm, 3/4 inch rounded oval dull pieces in it. My advice to them would be to start giving a you know what about whats in the bin or fill it with mulch and arborvitaes.
