Illinois Bituminous Coal Quality

I use anthracite by the bag and sometimes see a difference in some of the bag coal from the same vendor. Not a lot, but a difference.
I see no reason why bituminous would be any different except maybe more noticeable.

I wonder if the ATF temperature of antharacite changes much? It's the parameter that seems to give the most problems in burning coal especially the bituminous users.

Somewhere on the web I saw a chart of analysis for all the coal in the US. I believe it ran all the mines, about 100 or so were listed. It started with anthracite, then bituminous and lignite.

and the director of the Coal Research Facility is an acquaintance. He is sure to be able to answer all the questions I have about SIU’s coal and any lab reports.

Hey Nuke,

What did you find out from SIU about their coal?

I did email the head guy at the SIU power plant, but got no reply. Upon asking my dad about this he said that they probably would not hand this report out to anyone because of legal type EPA issues. So I decided to pursue a different route.

One of my friends is a mining engineer and has given me some contacts of professors at SIU. The next time I swing by, I am going to hit them up (they are the floor above the electrical program I just graduated from in December). He said one of them is connected with Knighthawk and my friend had a tour there with him. My friend said he had done all those tests on the coal as part of the curriculum, but he has since went to work in the aggregate industry.

In other news, I have been hard at work re-engineering a heating system on paper. I will detail in a new thread.
