One winter in the last 20 I got enough, long enough frozen time to experience wet frozen firewood put directly onto Hot charcoal beds. No even close to understanding like the upper Mid-West US guys or those central plains Canadians fellows. You and I think we know the cold from our days of experiences. Most of the time a fellow just has to live year after year to really develop a gut-feel for these kinds of things. Ha! Ha! Farther down your instance that hot air humidity IS significant beyond just what the calculation numbers will say. This is one of the best statements of purpose that I’ve ever read here on the DOW. In a double flute conciguration the holes must point upwards a few degrees. Progresively smaller if you feed air from only one side. Holes shud be at least 2-3" apart and not too big. In any flute desigh, you want a flute thats about 2" in diameter with at least 8mm thick walls. Others caught the idea and developed it further so its probably best if you ask them. The double flute has since served in the blacksmiths forge. Yes, l proposed the idea and made the first prototype/proof of concept but l only ran that for a few hours as a test since l had a WK hearth ready for the build. Then the hydrogen unlocksthe potentisl of CO. We want the hydrogen mixed in, wich has an extremely fast flame speed to eaven things out. But the poblem is, althugh CO has a rather high caloric value, its a slug when it comes to burning so its not realy efficiant in an engine. And it does feed the gasifier with “food”. But in reality its above say 10% when we start some serious hydrogen production. 1m3 of air weighs 1.3kg so thats something like 4%? Not much, at best. Google says at 30c the dew point of air is 50g/m3. Bottom line, exhaust contains some H2O and CO2, in this location. CO2 is a gasifier fuel raw material, provided you have sufficient excess heat. Certainly you would agree there is CO2 in the exhaust, as that is what happens when the CO is burned. So, water vapor is in exhaust, here at least - no way around it. (It ran so well that day that I decided I never would run it on gasoline, again. I wish it weren’t so, as not running my Motofier on gasoline after the long Mother Earth News run, ten years ago, or so, left me with rusted rings and a stuck piston, necessitating a major overhaul. Meanwhile, the engine is mixing humid air with this charcoal gas (with some amount of water vapor in it, from the humidity, as mentioned above). But that water vapor in the gasifier product passes on through to the next stage, the engine. That is going to yield some water vapor, and hopefully a little hydrogen. So, around here it is so humid you can almost cut the air with a knife! You are burning ambient air in the charcoal gasifier. Can’t figure out how to delete that previous reply, or maybe it is not visible since still processing … And here’s my previous reply, which I guess I goofed up by adding too large of a photo file, perhaps.
