[Stoves] Pellet stoves without electricity

[Crispin Pemberton-Pigott]

That looks like a hopper-fed, crossdraft wood pellet gasifier. Maybe Alex E can comment as he builds such things.

It looks well made.  From the look of the combustion area, I think it will have high excess air.

To Paul A: I think this is a wood pellet version of the KG4.4 coal stove without a tilted grate (which would help a lot if it was). The open space on the sides is going to allow too much air to get into the flame.

The winner of the 2016 wood pellet burning competition at Livermore National Lab had a second place award for a stove that worked in this manner (hopper, baffle to prevent over-fill, air around), except it was a downdraft stove. It also produced 50 Watts of electrical power – 2 amps, 25 VDC.

Thanks Roberto

Hi to all,

Recently, I found that there are two new very interesting pellet stoves available in Chile. They use a new technology, that do not require electricity to operate.

Both sites are in Spanish and have pictures and videos of the stoves in operation.

I have seeing one in a store, and I think that the operation is very similar to a mini-rocket stove. The grate is small.

With this design, maybe it is possible to adapt it to design a cookstove with continuous and gravity pellet feed.
