First Red Ash is not made by the carbon It is made by the amount of Iron in it As it was formed Some coal Veins has Higher Iron content Then others That makes them Red Ash Veins Second Sherman coal should be white ash not Red Ash I live 10 Miles from there breaker I have Burned Tons of There coal it is always white ash Do to the Vein of coal there in Unless they have moved to another vein or Mixing there coal with some one's elses The last Time I bought it Was 12-21-06 So They could of change They were geting there coal from Black Diamond Mining INC Refuse coal . and Mountaintop coal mining INC.Surface mining coal Both are up in the Elysburg PA Area Kimmel coal gets there coal From Meadowbrook coal co.Inc REFUSE Coal Lykens PA Here are some Links to show you Unless you are from this Area you would Not Know thisrberq wrote:Can someone explain to me why one coal compared to another would make 100 degrees difference in stove temperature, unless one was drastically inferior? I have tried three different types -- Blaschak, Kimmel, and "Sherman" from a bulk dealer who bags it himself. All resulted in about the same residual ash, which says to me that all had roughly the same carbon content. So, one carbon atom being like every other carbon atom, it would seem that all three should have produced the same total heat.
I'm not trying to dispute those who have found noticeable differences between brands, I'm just trying to understand what accounts for the difference????
e.alleg wrote:Well to further the discussion the Blaschak makes a real dark red ash, vs the other stuff I've been burning makes a pink/grey oatmeal color ash. The Blaschak also makes less ash, at least 20% less in the pan. Consumption seems to remain the same, so I don't really understand where the extra weight is going if it's not making heat or ash, maybe it's burning up into flyash.
The Ash Content real don't mean it will burn Hotter It is the Iron Content that Makes it burn Hotter Like Red Ash coal What Makes Ash content Higher in some coal and lower in other is the amount impurities/ dirt that was formed with the vein of coal or when it is mined If you go to a good coal Breaker they can get most of the unwant's out of it when they process the coal some have to put some back in with the coal if the ash content is to low because the coal will not burn right it will clinker up expecially in a stoker stove / stoker boiler any unit that has force air helping to burn the coal Lower ash coal is not always the best any coal that is under 5% will not burn correct that is why some breaker and more coal dirt back in to get the ash content up so it can burn correctrberq wrote:coalberner, I did burn a few bags of Sherman, and as you say it was white ash. Seemed to burn quite well, but I couldn't quite get linked up with the dealer when I needed to buy -- he is new to the business and seemed a bit disorganized. Next year I will try a couple tons, or maybe this summer if he's giving off-season discounts (I wonder if that happens????)
I still want to know why some coal burns hotter than others, assuming the same ash content in both???? Anybody know????
Ed if was 5% ash it would of clinker up maybe 7 to 8% with blaschak you will never see 5% with it most of it will be 10% and up The problem with them is they mine in three different counties and are in 16 different Veins of coal so you never know what coal you are buying They have two breaker's The Quality is to inconsistent same goes for Reading witch most of there coal now is Refuse look at the linkse.alleg wrote:Well I give up on trying to figure this out. I burned a 1/2 ton of Blaschak and the ash was very dark red and there was very little ash, about 5% if I was to guess. Keep in mind the bags all look the same, the Santa Clause bags. Yesterday I burned 160 pounds and the ash pan was overfull with a very light Grey ash for most of it. That means some of these bags contain coal that produces 20% ash, some produce 5%, it all costs the same and is impossible to identify when purchasing. I wasn't watching the fire but I suspect the higher ash stuff takes more coal to keep the house warm, 160# is a lot for one day.
