lehigh anthracite has anyone burned this coal...please give ur comments

Forum members Townsend and Pacowy each got 20+ ton deliveries from Lehigh this fall and gave it "two thumbs up".

Lehigh Anthracite

If you are shopping for a TT or triaxle load, I wouldn't hesitate to give them a call.

They are in the top two in coal, I do know right now though they are pulling alot of red ash

Matt, please explain why that woud be a concern. Is their ash content running abnormally high, or is there something generally undesirable about red ash in particular?

Red ash coal is an indication of high iron content in the coal,and frequently this is the culprit in clinkering problems

I wonder why and how Harmony coal got to be all the rage, as it is very red ash.

Yes, and it will clinker severely if you get the ashes hot enough.

I will admit my ash pan has been chock full of crunchy clumps. The AA/AHS grate system seems capable of chewing up and spitting out nearly anything (so far, knock on coal).

I have been wondering the same thing, UAE is very red ash, and its not just a clinckering culprit, but red ash coal having more iron ALSO means less carbon...

Even if the total amount of ash is very low?

Look you can have shitty red ash coal, or you can have shitty white ash coal, what im saying is if you have EQUAL quality of coal white as opposed to red, the white will be better coal
Ill put it to you this wayIf I have a Ton of coal, one with NO iron and one with Alot of Iron which one do you think is gonna weigh more per 5 gallons? fill a 5 gallon bucket with carbon(charcoal) and one with carbon and iron, which weighs more??
You will get alot more coal in your ton with white ash coal, and alot less weight from by products. I just put an analysis in the UAW coal post for your info

Listen, I'm not arguing with you...just asking a question and trying to learn something. I don't get cranked up over the color of the ash anyway. For me sizing consistency, availability, and btu's/$ trumps the rest of the lab sheet.

What im trying to tell everyone is your fuel comes from the carbon content, so less carbon generally means less BTU. If you have red ash coal with very little other by products it could be very good coal, although your still gonna get less actual coal per ton because of iron weight.

The three most important constituent of coal are ash (inerts), volatiles (gas contained in the coal i.e. hydrogen, nitrogen and oxygen) and fixed carbon. If you add the percentage of each you should come very close to 100%. In regards to the never ending mystery of red vs. white ash; mineral analysis of the ash will reveal that silicon dioxide (SiO2) will be 50-58% of the ash, aluminum oxide (Al2O3) will be 29-32% of the ash and iron oxide (Fe2O3) will be 4-8% of the ash. A higher ash coal that contans a higher percentage of Fe2O3 will most likely have a reddish colored ash. FYI - Lehigh is NOT washing bank material. All coal sold comes from either the mammoth, forty foot, primrose or orchard veins.rrtaylor
