When fresh cut but looking very dry, a pile of straw lit on the side will smoke profusely and a pile lit on top barely smokes.

All piles smoke quite a bit when the flame goes out, which is when I'd like to see the embers smothered to make biochar.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Oct 11, 2022 at 10:39 PM Kevin McLean <<a href="mailto:kevin@sun24.org">kevin@sun24.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small">Thanks, Crispin.

<div class="gmail_default" style="font-size:small">Moisture content is obviously important. Please look at this video where we compare the burning of two piles of freshly cut upright maize stalks that were brown and looked dry. (You may have seen it on the
biochar listserv, but it is also relevant here.) We are demonstrating the difference in smoke when a pile is lit on the side (left pile, the traditional method in Africa) and when lit on top (right pile, the way we train). The difference in smoke is stunning.
However, when we compared two piles of stalks that were cut two week previous, both piles burned with little smoke. I attribute this to moisture content. Brown upright stalks must have a higher moisture content than stalks that were cut and left on the ground
for two weeks.</div>

Some of the principles of the top down burn of large piles of maize stalks are probably involved in the burning of stalks in bands from the top.</span></div>

The metal band with the stocks upright is probably a better way to make use of the maize stocks. From watching your videos it is clear this is functioning as a hybrid between TLUD's and flame caps. Do you make any attempt to regulate the air from below? When
we go to Aprovecho I can easily make a band and we can do emissions testing on this new arrangement. I still plan to compare emissions of dried maize stocks versus maize stocks at ambient relative humidity. I think there will be a difference. I'm also planning
to do this in a metal band versus the "conservation burn" style you originally worked with. Let me know what you think.<br>

We've long been trying to find a way to use maize stalks as a cooking fuel<br>
in Africa. They are challenging because they burn fast and smoky. We may<br>
have found a way.<br>
<br>
Make a bundle of stalks in a metal band and stand up the bundle so the<br>
stalks are upright. Then light the top. The band has a diameter of 20<br>
cm. The stalks burn remarkably clean for about 13 minutes, no tending.<br>
Then a new bundle can be swapped in to continue the cooking. Below are<br>
some videos.<br>
<br>
My colleague in Uganda thinks that farmers with two growing seasons can<br>
cook year round with maize stalks and never need to collect firewood again<br>
... we'll see.<br>
<br>
As a bonus, this makes biochar.<br>

Imagine you rise the sleeve higher up and leave some space between it and the bundle.<br>
It should have a "secondary air effect", I guess, and burn even cleaner.<br>

Subject: [Stoves] ***SPAM*** Maize stalks as cooking fuel in bands and bundles<br>
<br>
We've long been trying to find a way to use maize stalks as a cooking fuel in Africa. They are challenging because they burn fast and smoky. We may have found a way.<br>
<br>
Make a bundle of stalks in a metal band and stand up the bundle so the stalks are upright. Then light the top. The band has a diameter of 20 cm. The stalks burn remarkably clean for about 13 minutes, no tending. Then a new bundle can be swapped in to continue
the cooking. Below are some videos.<br>
<br>
My colleague in Uganda thinks that farmers with two growing seasons can cook year round with maize stalks and never need to collect firewood again ... we'll see.<br>
<br>
As a bonus, this makes biochar.<br>
