Look at this wicked cool stove

[smwilliamson]

I was down in Brookhaven National Labs, long Island on Wednesday judging the pellet stove design challenge. This stove won a Vesta Award in 2012 or so and I got to see it up close. It uses torrified pellets. The final version of this stove that has the patent pending I think torrifies the pellets to before it burns them. The burn pot on this baby is about the side of a mason jar and is made of a glass cylinder. The burn pot temps get up to 1500 degrees or so an nearly all of the ash is incinerated. The combustion blower mounts outdoors so the stove is virtually silent in the room. Heat exchanger gets up to 1100 degrees above the burnpot and the whole stove radiates out the heat. Fairly certain the whole stove is aluminum. It didn't win but the stove gets my vote and love. It was my favorite. No auger. No digital controls. No noise. The bottom grill is spun backwards so we could look in but when it's spun forward the stove looks like a space age tractor!

Wow, I want one.

And the lab is not far from me... I didn't even know they had a pellet stove competition.

Thanks for sharing the pics.

If that didn't win where are the pics of the one that did?

Okay, educate the uninformed - what is a terrified pellet?

Good explanation here: http://www.pelheat.com/torrefied_wood_pellets.html

That is a SNQ radiant heat pellet stove. Made by Snoqualmie Stove Works in Snoqualmie near Seattle WA. Absolutely cool looking stove and the extended use of aluminum is not just for the looks... aluminum is a much better heat conductor than iron. Here we can see a working prototype. Enjoy the silence!

That would be the pellet on its way to the burn pot that reaches temps of 1500 deg. I'd be terrified wouldn't you

Now if they could just sell pellets at a price 50% less than current we all might have something worthwhile.

Brilliant!

Possibly quartz, not glass?

Is that std pellets atop the darker torrefied pellets functional or just for the photo shoot?

But copper is the best just maybe not for this application. Science fair project with one of the kids years ago. Copper, aluminum, then stainless steel.

Not sure about the torrefied pellets ... cost more? use more energy to produce?

Interesting stove design ... give it time though, they'll put digitalized bells and whistles on later

 

[Bioburner]

they'll put digitalized bells and whistles

With a higher probability of problems
Al is way cheaper than Cu.
I like the idea of external exhaust fan, was adopted from another stove design.
Design looks like it should be on a Star Trek or Star Wars movie set

I had to look it up -- melting point of 1,984, so I guess there would be some safety margin.

I believe that stove has been around since at least 2007. I found an old thread about it:

They could use gold it has good properties for radiating heat.

Wasn't thinking of melting point, just conductive properties

Kind of looks like a mad scientist Tesla experiment gone awry.......interesting though. Having that combustion motor further away from the heat might expand the life expectancy of it.
