I was curious about how the Stockton coal stacks up against Lehigh. Has anyone compared the two in a hand fed? I just found out my coal is Stockton from Hazelton, I had thought so but wasn't sure. I looked up the specs for Stockton online. All comments welcome.

Stockton Mine Mammoth Vein
Typical Analysis: Proximate Analysis as Received

% Carbon 82.04
% Sulphur 0.61
% Ash 9.34
% Volatile Matter 3.71
% Moisture 5.92
Hardgrove Grindability 29.54 HGI
Heat Value (daf) 14,844 BTU/lb (8,246 kcal/kg)

This is what I found on the Lehigh site.

Low sulfur: <0.75%
Ultra low-volatile matter: 3.5 – 4.5%
High fixed carbon: 83 – 90%
Ash: 7.5 – 12%

They both have high carbon, low volatile coal. Lehigh might have the edge on ash content right now, but I have not tried any from Stockton in over a year. I think it is best to make your own judgement - get some of each and see if you notice a difference.

For those who do not know, "DAF" means "dry and ash free". To compute the "as delivered" BTU's per pound one must factor the water and ash back in.

I will tell you Lehigh just has a range on our site, we do however test daily and we are generally much better than the ranges you see on our site..

I just committed to the purchase of 5 tons of bulk Lehigh pea, and I'm presently waiting for my supplier to take delivery. During my discussions with the supplier I was informed that since Stockton and Lehigh both come from the Mammoth vein they share many of the same essential physical and burning characteristics, but Lehigh is much cleaner and free of rocks, etc.... I have had problems burning Stockton during the non-heating (summer) months in the past, so given their overall similarity I anticipate similar issues of Lehigh, but I have planned in advance to burn Blaschak during only non-heating months, and Lehigh during only heating months.

It is good to have plan B, but I do not expect you will have any issues with summer burning with Lehigh coal. Our EFMs are loafing along with it just fine.

Fred, low ash and a fair delivered price were strong motivators. My Blaschak suppliers price is ridiculously out of line high this year.

I’ve been burning Lehigh in all year for 30 plus years Fred. We have Amish people who burn in hand fed stoves all summer long as well. Where some people run into problems is we have lower volitile content.

Ash/birch vs red oak. One is great for short fires/slow burning, the other is great for cold winter waether when you really want some BTUs (and less tending).
