[Stoves] RE Retted Switchgrass Fireball Test

[Boll, Martin Dr.]

Dear Jeff and Crispin

 

Following your burning tests and Crispins comments to that, I want to draw
your attention to a French website, which I brought to the list quite a time
ago, with some word translations. Tom had put the picture to be simply
accessible to the stoves-list members. I wanted to look actually where it
was, but I think that picture is in an older version. I don't know the right
address. But I give you here one of the original web-addresses (The most
informative one) of the DEOM-Turbo-stove. You will not need an English
explanation to understand.

 

It is one of the burning principles I favour for stove constructions if
possible. The idea in that stove: Blow by draft.

It is just the principle Crispin tells you to use: blowing against the
burning tips: Here blowing against the burning surface.

And more: By the deom, the secondary air is preheated, possibly the
important point for burning your Switchgrass-balls, as Crispin says.

I think you will use a fan instead of a ( -I think they use a 6meter high-
house-)chimney 

I am curious to know, what Crispins Libhubesi-stove would make, if some of
the air came from oblique above, and the end of the rocket-shelf was built
as a grate with small spaces to contain most of the charcoal, not to fall
down. (The end of the grate bars bent 45 or 60 degrees upward, for the same
reason and for not to put the sticks too deep into the loading-hole. The
side-bars of the grate could be a bit higher to form a border for the small
charcoal-pieces.)

 

The company selling the DEOM-stove says, that this stove can cleanly burn
very different fuels, besides different shaped wood even saw-dust, paper
(untreated!) and other waste. In realty I don't know this stove, but I would
like to see it in action with different fuels.

Good burning and less smoke,

-though against mosquitos a little bit :-) -
