Then I saw this video... youtu.be/E1ujbhBDpKs This one confirms that carbon monoxide burns blue. A beautiful blue....
So in a TLUD the wood gas is filtered through the hot coal bed and is mostly Carbon Monoxide hence it burns blue.... When you cool this gas down it also smells tarry.... So we know the other compounds are still there. Maybe they are finer.
It would be interesting to know the CO emissions of TLUDs that burn mostly blue.
From my measurements the blue flames are not any hotter than the sooty yellow flame.
I agree, the blue flame indicates a more complete combustion. When I run my gasifier, I get it up to temperature with a burning blue flame on the flair off tube before diverting it to my generator. I use a cyclone filter followed by a media filter to remove particulate carbon and any unburnrd tars in the syn gas and therefore can get a blue flame. The blue flame is the sweet spot for the gasifier. In my tlud I can get a blue flame once the fire is well established and the coal bed is completely covering the top. I still get some soot on the pot, likely as you mentioned that some tars have not been cracked and then condense on the bottom of the pot.

I have only used it to run a generator, but with a modification it could be used as a burner. A tlud is much easier to set up and use as a burner, just wouldn't have the prolonged burn I could get from the gasifier. In that use I would need 12v electricity to run the blower. With the generator no blower is needed after warm up as the generator pulls the gas as needed.
Speaking of blue flames I have often complained about the standard RMH yellow flames. My RMH is a bit different and it heats a 330g IBC full of water to 150F which in turn heats radiators and the direct heat off the stove is ducted to our kitchen above as well as heating our 900sf garage and 1600sf basement. The beautiful blue flames that burn below the logs and firebrick grate can be viewed on YT under Fiskfarm. Blue flame vid here link:

deadstarsstillburn: Hi there. I was directed this way by folks on the Permies.com website and am hoping I can get some information on how a total newbie can get started designing, siting, building, and not-dying-in-a-horrible-house-fire with a new RMH in a 160-year old home

deadstarsstillburn: The people over there recommended either a 6" batchbox or an 8" J-tube. I don't know what those are but am going to try to figure that out. What I need is a blueprint that I can scale to fit the need for my house. I have something likne 5000 square feet

deadstarsstillburn: but I do not need to heat all of it by any means. probably only need to heat half of that, maybe less.
Oct 21, 2020 6:53:15 GMT -8
deadstarsstillburn: moreover, the house has 3 storeys (large attic) so I assume if I get very efficient heating on the ground floor, that will go a long way toward heating the upstairs as well, no?
