you are thinking of activated charcoal, not biochar, or any other sort of normal charcoal, infact most charcoal is created at rather low temps, cause higher temp will cause said charcoal to combust. its not made in a vacuum, some 02 can and will get in.
Activated charcoal is made using high heat, similar to biochar, but that is where the similarities end.
Chances are after passing through the air valve some air goes to the bottom, primary air and some up higher to do secondary combustion in the uppermost chamber you described. If you modify the ratio of the air split to burn off the coals probably secondary combustion will decrease.
Sorry you feel that way. I dont know it all, but there are a lot of youtube videos promoting wrong information. You might be a victim of watching a few of those as well.
thats a great big bingo, though small amounts as a supplement do just fine, and will just keep adding to the soil as they break down, not sure I would order 10yds of charcoal and dump it in the backyard like Hey MA, WE'RE GONNA HAVE SOME KILLER SPUDS THIS YEAR!
Nothing to do with Youtube funny enough, but knowing the difference between charcoal either purpose made, or secondary and activated charcoal, from my own research in how to feed my forge lonnnnnnng before you could simply look it up on the youtube, **** before I was old enough to even drive. If you took the time to do just the modicum of research before spouting off you would know the difference as well.
A friend of mine puts a 30 gallon steel drum inside a 55 gallon steel drum. The 30 gallon drum has no holes in it, the lid sits on top. The 55 gal has a bunch of holes at the bottom on the sides. He loads up the 30 gallon drum as tight as possible with wood, puts the lid on and then puts a rock on the lid. He packs around the outside of the 30 gal drum but inside the 55 gal drum with wood, and lights it. He keeps the wood burning until there are no more fumes coming from the 30 gallon drum then lifts the 30 gal out of the 55 and sets it on the ground to cool. That's how he gets charcoal to use in his Green Egg.
I hate to break it to you, but I am probably as old as you are and was also around way before youtube. I have also spent 3 years researching soil fertility including Biochar and Charcoal. I have attended seminars in Louisville Kentucky, Charlotte Nc, Athens Ga at the University, Nashvill tenn, and even at the home of a Marcus Wallenberg Prize winner, widely considered the Nobel Prize of Forestry, in Frogmore Sc. The fact that you dont know the difference and are not willing to listen to any other opinions on the subject speaks volumes. You can believe what you want to and for your general use of burning in your forge and grilling a steak on your grill, you're perfectly fine doing what you're doing. But if you are trying to build soil fertility and wanting to use Biochar as a tool. Then your opinion are just opinions, not necessarily wrong, just lacking proper context.
And even though I dont normally agree with Del, He mentioned this also.
So while I stand by my statements that none of this matters if you are wanting to use your stove charcoal in your grill, or in your forge, it does matter if you are trying to make biochar and use it to build soil fertility. I will also state that you can use the charcoal from your stove in your garden but expect a certain amount of nutrient tie-up until the charcoal can naturally absorb the necessary nutrients already available and naturally found in the soil. I will also state that Charcoal and wood ash are not the same, as you suggested in one of your other post.
If you had watched the Youtube video, and, , you would see that the students are making syngas from the wood smoke. And dont forget those wood fired cars that run their engines off the gas created from the burning wood.
Notice the use of a sealed drum inside a drum to create an airtight chamber for the charcoal.
Carbon is carbon, nothing more or nothing less and I have never said otherwise. Even a diamond is carbon and will burn if it gets hot enough. As for getting angrier, try looking at yourself. I am not angry. I know the difference between charcoal, activated charcoal and biochar and they are all made from the same base carbon sources. For charcoal, the material is usually wood, but for biochar the source can be any organic material, even elephant poop. Biochar is made at higher temps than charcoal to preserve the internal structures of the product. This allows the biochar to uptake and hold more water and nutrients than charcoal. That is the only real difference between the two products. You can use either to fire your grill, or grow your garden, only for growing, biochar is better than regular charcoal.
