First year using Black Locust extensively.

We're still burning some of that BL we swapped pecan for. Bring in a few pieces for those really cold nights.
Had white oak, BL, BB split and hickory chunks for overnight load last night...

 

Yep, we mix it too.

 

I just got off the phone with a friend of mine who has an OWB and he mentioned he doesn't like locust. He only gets a 5 hour burn before it needs a reload. I do not know what size splits he is using but I do know he likes to cut at 24 inches long and split size more than I would care to handle. He may not be burning the driest wood either.

 

That pretty much sums it up for me too.
1 or two pieces at a time.
I think it does better in old school stoves...not much gasing off, just burns like coal

 

Same issue I’m having with my Honey Locust! It burns very slow with very little flame. I mix it some maple to get the flames going and burn down the coals. It does leave some nice coals on the morning after overnight burns. I would say it gives out a much slower longer lasting heat. Not good when you want to get a quick hot fire going.

 

I’ve had the same experience with honey locust (never burned any black locust that I’m aware of). If i fill the stove up it is a very short burn and a lot of coals. I believe the btu rating for locust… it just takes forever to release its heat. I’ve had enough buried coals for a matchless relight after 72 hours with a stove stuffed with honey locust. But I have found that it doesn’t release heat fast enough to keep the house warm when it gets down around zero. I have taken to using it for shoulder season wood and really like it for that. A couple of splits will coal up and release low steady heat for 12-14 hours in the NC30.
