I know these questions must seem strange to you guys but I'm trying to figure out a "mix" of coal that I like.I like white ash because it's ash is EZ to shake down,like wood ash.I like red because of it's BTU value.I have a lot of superior but I sort of forgot how it shakes down and I only burned 10 bags last year and couldn't get a "feel" for it except that it made a LOT of heat with less air.I also looked back at a post with the temps of some of the better coals.
Calvin Lennig 525F
I haven't read a lot about Calvin Lennigs coal except it has good heat and 10-11% ash.Is it red or white ash or both?
BTW, I just got some Sherman coal(1.75 tons).I'm running out of room in my cellar
.Been burning it for 3 days now and it seems good.All white ash,shakes down EZ and no clinkers.Heat isn't as good as Superior but not bad.Better than the mystery coal I have.My coal guy said he talked to the guy at the breaker and was told that Sherman is pulling all their coal from the mammoth vein now.Don't know if it's true or not or which mammoth vein it's from.
After studying different coals I think I may try Summit next,sounds like a mix I would like.Mostly white with some red for heat.
I'm not buying any more coal this year until I burn the Superior,keeping that for the cold weather.If it shakes down EZ and has no clinkers next year I'll buy just Superior in the spring so I can get all 7 tons and be done with it.This year I got 5 tons in the spring but when I went to get more then said no more out of state
I do enjoy "playing" with different coal,so much to learn!
