I hear only good thinks about Direnzo. Can't wait until spring until I get my boiler, that's all I plan on burning.

I got an email back from Direnzo. They said their coal currently is 180 a ton and 9-10% ash. They are reporting " pinkish/tan" ash. They sent a picture along and it didn't look a whole lot different in color from the mammoth materials coal I have. I also spoke with Jeddo coal company. They are reporting 10- 10.5% ash. They said the ash is white, which I can verify from the quarter ton I bought. It is very fine very white ash. They said they are pulling from the mammoth vein about 250 feet down. They are about 160 a ton. I forget the exact number he told me. I will be loading up on Jeddo this spring. I am extremely pleased with how it is burning. I let it go 14 hours yesterday with stove at 400 degrees. A quick shake and 2/3 of a 5 gallon bucket and I was good to go again.

Update: Back to burning mammoth coal. I burned the stove(not flue pipe) at roughly 550 degrees last night. After about 10 hours the front of the stove was out, had to do a lot of ash poking to clear the front. Added just over a 5 gallon bucket of coal to refill. Very disappointed to say the least. It looks like now that it's finally starting to feel more like winter instead of spring, I will have to do the stove 3 times a day. Which translates to about 2 1/2 five gallon buckets of coal a day :mad: :mad:

Anyone have any recent reviews on Mammoth coal? May need an option for dry coal, Direnzos has been freezing by the time I get home :(

Thanks,

Joe

i burned it already, i used to live near there. that was when they first started delling coal tho, like 2006ish
the problem i had was it was inconsistent.
there was also some rock in the coal, kept breaking shear pins on the efm.....i was burning buckwheat coal then too. i am sure they have a better breaker now or someone proceses it.

they didn't even have a scale a few years ago!
i had them deliver quite a few triaxles of stone to the place i used to live. never a weight, always a very full truck. the 2b modified has coal in it hehe.

I'm sure things have changed in all the breakers since 2006. Ya don't go, you'll never know! That 2014 pix on prior page looked real good.

yes much better, sorry i am sorry i forgot to type that part.......the coal is processed off site, someone posted about it a few years ago and i do remember getting one load there a few yrs ago when there was a localized rice coal shortage (it got stupid cold lol)
i would still test the waters as with any new coal, kinda hard being out of the area tho. i usually test a new supplier with 800-1000 lbs, if i like it i go back.

Yeah, wish I was closer to test a small batch.

Only truly bad coal I ever got was early last year, bought a ton of nut from a local supplier (who I had used before with good results). Never before in my life have I had clinkers like that (or at all, really). Entire hand was blisters from shaking, and I’ve never had that happen since I switched to coal in ‘11. Grates would jam tight EVERY time I’d service. When I shut down to clean before switching to Direnzo, I pulled several baseball sized clinkers out of there 😳.

Leary of anything different after that mess lol.
