Wood gas oven




by gaeldk » 21/06/07, 08:20

Hello,

"Woodgas stoves" in English.

Here is a video of a forced convection oven:
http://www.youtube.com/watch?v=pyofhLYYVC8

The author says that it produces 10000BTU for almost nothing of wood.

First, does anyone have plans for a forced convection oven?

Then a simple solution would not it be to connect a small oven like this one to a sterling to generate electricity on demand?

10000BTU is about 3000W so if we consider the efficiency of a sterling at 80% and the efficiency of an alternator at 50% there is still a more than 1KW ....

I did not understand how this oven works. In any case, there does not seem to be smoke.

I think this oven is based on the principles of the gasifier.
It seems that the battery pack is used to ventilate the stove.
Upon ignition, air is drawn in through the holes in the circumference (top) and spit out below to activate combustion.
In normal operation, air is sucked under the wood and spit out through the holes in the periphery. It is the gas pumped under the wood that ignites out of the holes.

For more info (or to buy this stove for $ 55): follow this link (English)

A little internal research on Gazogène

Surprisingly (because the pure system yields are generally low) and according to Jancovici, wood gasification is the biomass energy process that would have the best overall performance.

It's in his last book: please fill up if I remember correctly.

Another question, are there boilers on this principle?

Uh ... cogenerators you mean? Yes see the links at the bottom of this page: https://www.econologie.com/le-gazogene-articles-698.html

There is something I do not quite understand, if this reaction gives more heat than normal combustion, why do not all wood pellet or pellet boilers work this way?

Because, it seems to me, it requires "reverse combustion" burning which is not always easy to achieve, I believe.

Hello,

Go for the tired wrist, a good link on theory and practice:
http://www.garlington.biz/Ray/WoodGasStove/
http://e-woodgasstove.blogspot.com/

Otherwise a good search with your google friend on "woodgas stove"

Good camping
