Burning Walnut shells, anyone try this?

I've burned hazelnut shells from time to time. Sure would hate to gather cords of them for the winter ;-)

I have saved and burned nut shells 1 time to see how they do and they put out one hellish heat.

I'm laughing. I thought I was the only "nut" fascinated by how well pistachio shells burn.

There's an electric plant near my property in Maine that burns wood chips mixed with peat moss to power the grid. whatever is plentiful seems to work.

Don't they also put walnut shells on roads instead of or over dirt?

I think they do it down south.

I love walnuts, maybe ya'll just gave me another reason to buy them!

My wife has taken to burning the hazelnut shells that she consumes, and she showed me how it worked tonight.

Quite the little glow of heat! Looks like we aren't the only ones that have gone nuts.

Dont know how they work in a stove but they are used to clean gas path of a jet engine. Crushed walnuts are sucked into intake and clean dirt from the blades. Also when i rebuilt my intrepid there were acorn shells in the refractory package. Maybe i should have left them there. Just kidding.....

Wha???

How about hickory?
If I could burn hickory shells/nuts I would never have to worry about wood ever again- I am swimming in them!
You seriously can't walk in my woods because they are so deep.

Hickory nut is a member of the Walnut family, so I would think they should work. I've also read the Hickory nuts usually have a pretty high fat content. Are you considering burning the whole nut or just shells? You'd probably get more energy burning the whole nut as the 'meat' is where a lot of the fat is stored. Although, if there is a market for the nuts, you might be better off selling the meat. Don't know as I've ever seen 'hickory nuts' for sale though?? Maybe a regional thing. The big deal around here is pecans.

Hickory nuts are a real pita to crack(really hard thick shells) but they taste great. Your right about a bumper crop in Ky. though. I don't recall ever seeing so many nuts. They were practically pulling the trees over a month or so ago. It's supposed to mean a tough winter. We'll see.

how do you keep the larvae and mice/rats out of the nut bins ?

What about acorns from oak trees? I remember throwing them in the campfire as a kid just to hear the pop!

I tossed in a small load of about 60 whole black walnuts (2 years old) last night on top of a good bed of coals. They cranked... still pretty solid after nearly an hour, lots of heat - looked like a pile of charcoal briquets. The fat in them may have gone rancid, but the BTUs were sure there.

We burn the shells of chestnuts sometimes.

Are you seriously telling me I can burn these?

I don't believe there is any market for the nuts- heck, I can't even find a viable recipe of any kind that uses pignut hickory nuts.
Not that I have looked all that hard :down:

More BTU's than wood? Well that does it, I'm going to burn some walnuts, Brazil nuts, and peanut shells tonight. I remember doing this last year in a fireplace but noticed that a lot of the peanut shells didn't burn down to ash despite a hellish fire of oak wood. So I stopped burning them. But with all the testimony here, I suspect my stove will burn these shells without a problem. Glad to hear this is working for others. . . I always hated throwing shells away.

What else have you guys been burning? Or what other "plants" burn well? Coconuts?

Do pinecones have more BTU's than pine wood? Ahhhhh I think I have something there?

Peanuts aren't nuts, they are legumes(beans). As such, the shell is not a shell at all, but a rind. That probably accounts for the difference in burn. The fact that they are so much less dense than other nuts would also lead me to believe they would be ebetter suited for kindling than fuel. They take off really quickly, but are usually gone real quick. However, we did an experiment in health class that involved testing the difference in burn times of fats and carbohydrates(to show why the body metabolizes carbs faster than fats), and the peanuts burned for quite some time with all their fat content. Whole peanuts , then, are fairly interesting as they would be fuel already wrapped in kindling!


Edit: It would appear this thread is turning into an "Alternative" Alternative fuels thread!

I've heard about using crushed walnut shells to clean out the intakes of automobiles as well. I guess any leftovers are incinerated in the combustion process.

I'm burning leftover feed corn with just a small amount mixed in with the pellets in the pellet stove. The cobs go into the wood stove.

I would assume these nuts have to be seasoned.... right?
If they are ripe and dried out enough that the shells have split, would that be considered seasoned, or do they need to sit longer?

I would imagine the shells would season pretty quickly, but the meat probably takes much longer. I don't think the shells have much moisture content once the green husk is removed. If the shells split, then I would say they are seasoned.

I fully intend to try burning some hickory nuts this winter.

as posted above, BUMPER crop this year, I cant even walk in the back yard without slipping on them.

I am happy to have maybe found another use for them ( burning)

so far the only use I have gotten out of them is to hurl them, baseball pitch style, at my sons rooster.

I bought 2 pairs of retread tires from treadwright tires and the tec told me they use wallnut shells to
give them extra grip. Interesting. They run great.
