Thought I would chime in now that I'm about a 6+ weeks in with the GlenBurn/Mallard Contracting coal. I bought directly from the breaker and had trucked in. Very easy to deal with- friendly folks and probably the easiest transaction yet when buying bulk coal. Net cost on site including trucking ended up being about $200/ton for a triaxle full.
The coal itself looked clean but I had far more fines than I would have expected towards the bottom of the pile (which is what I am burning now). I did not see any other extraneous debris. The coal color was "duller" and less shiny than the old Harmony. Size looked very uniform (other than the fines noted) and feeds fine in the stoker boiler.
MUCH MUCH more ash (about 60% more) when compared with the last of the old Harmony I finished burning in November. I am running a LL220 Boiler and with the new fans (Thanks Matt & Dave) and with lots of additional patient counsel by Matt on tuning the system the boiler is keeping pace although it has to run flat out to do so when temps are <5*F and the house temp can't keep up once <-5*F. I am finding a fair amount (maybe 15% total volume of ash) of unburned stuff/rock/partially consumed coal in the ash despite getting the "complete burn" with about 1.5" of ash on the end of the feed ramps. With the very cold temps we have had the last couple of weeks I am burning about a full bin (300-320 or so lbs/24hr period) which is consistently yielding about 36-38 lbs of ash (after tare for the ash pan) so roughly about 12% real world number ash content for this load of buck.
If I was using the old Harmony as a standard and a "10" this would probably be a 7.5 with points off for increased ash and the fines found in this load. Disclaimer would be this is the first coal I've used other than old Harmony after Greg (LsFarm) and Coalberner hooked me up with that when I started burning coal right up front.
I would rate the transaction and business end an easy 10 and would gladly do buy from them again if based only on this part of the interaction.
