My question is:- How do you know the anthracite coal provided to you is of HIGH quality??? do u ask for some lab report or something???

There are many qualities in anthracite toooo where VM ramains same 3%-5% But the Fixed Carbon varies and so does the price.....
Very sad that you didnt knew about it.

Welcome to the forum, but you are getting off on the wrong foot with your assumptions. Forum members discuss coal quality from the various breakers all the time. Except for those who live in close proximity to the breakers, most only have the option of buying a trailer truckload or buying smaller quantities from local dealers where only a few well known brands are available. It soon gets around which coal works best. Many members have decades of experience, so their reports are reliable. In the past we have had reports on very cheap low grade coal, which we avoid. A few members sell coal but most just burn it. For what you want I would suggest contacting the various breakers who can furnish you with lab reports and prices.

The anthracite coal that is strip mined is mainly on the flat pitch, a basin. As in the way that a soft coal vein lays. Which leaves the straight pitch, which was normally deep mined. When the vein lays on the straight pitch, your not dealing with a bed of coal under the overburden. Instead of a bed of coal that could be 30 foot thick, you get a seam of coal thats 30 foot wide. Yes it could reach depths of 2500 feet, but no surface mine is getting that. The seams normally outcrop to the surface, thats where we set up our deep mines and chase the coal vein.Thanks to MSHA, they just about put us all out of business. We are on the rebound again. Deep mined Anthracite for the majority is cheaper, and is of a better quality. Due to the lack of overburden that has to be removed to get a finished product.

There is no easy answer to your questions as there are numerous fields and different veins in those fields all with their own characteristics.

Fixed carbon is going to be 85 to 95%.

Ash content will be anywhere from 4%-5% up to 16%-17%.

The 4 to 5% locally is called white ash and can have a BTU content up to 28 million per ton. It has glass like characteristics, you can literally break off shards and shave with them. As far as anthracite goes is going to be the absolute king if you were looking the highest quality anthracite. Unfortunately it can be "too good" and be problematic in automatic stokers so it's usually mixed with "lower" quality coal.

On the high end of the ash scale is red ash which has a higher iron content. BTU is going to hover around 24 to 25 million per ton.

Typically the ash content is going to hover around 10 to 12% with BTU content of 24 to 25 million per ton red or white ash.
