Over 2 hours later and there still is a 5" ball shaped piece of wood burning. I need to feed it small pieces of wood because the hot charcoal bed was used up. Refulled and closed the door test completed.
I learned something here when running a stove like this. A mix of smaller wood is needed to burn these big chunks of hard cherry wood. Much different than burn in a open fire pit with unlimited supply of oxygen.
The day is about done and it is time to take God’s given Sabbath day of rest starting at sun down. The YEHOVAH God The Father is so good. And on Sunday as a believer I can celebrate the Messiah Yeshua God’s Son’s Victory over death into ever lasting life. This is the 8th day that also the 1st day, amazing Grace for us all.

Hi BobMac
I am glad you are picturing out your new-to-woodstoves expriences.
No; not exactly wood gasification.
But maybe now you can see it gets you much closer for full wood-fuel-use combustions understand than open air wood fires.

Hey BobMac here is a picture of my ash build up in my wood stove:
Yeah. A poor illuminated picture for sure.
But what it is showing is the only 1"/27mm of ash depth built up so far from my now using clean Douglas Fir fuel wood. This is from five ~7.5 cubic feet wheel barrels of DF wood.
Previously using the cottonwood after just two wheel barrels of wood I’d have 2X that ash and have to shovel ash out of the stove to prevent primary air inlet blocking.
Last winter using up three “free” cords of English Walnut wood the ash building up problem was the same.
It is at least a 10 to one ratio difference my conifers to my hardwoods.
As applicable to wood gasifiers you have to design and operate to flow down thru the much greater ash in most hardwoods. For ash problems; conifer woods are ash-easy.
The other very noticeable difference I see D.F. versus cotton wood, versus walnut is the energy releasing rate.
When truly below freezing into the 20’s F./-C I must use the fir to get enough heat energy output. The two hardwoods releasing energy slower over a longer time.
This rate-releasing I have found also has a noticeable difference in wood gasifiers too.
Winter using-wood-for-heating observations benefits much if you pay attention.

This is a 6" plus diameter 10" long chunk of cherry wood with two others that have been burned down beside it. All vertical installed this stove. The wood seems to burn better this way in this type of stove. Less smoke when adding wood. I can close the air off more now and get a longer burn time. I just keep learning new things about this stove. HWWH Have Wood Will Heat.

It is getting cold again and starting to snow. So I thought it would be a great time to inspect my stove pipe. I took the bottom cap off expecting a lot of black soot to fall out. The cap was half full. This is the soot in the middle of the pan.
on the right side of the pan is the ash soot I vaccum out of the stove pipe going to the stove. I reach into the pipe and there was about a 1/8" of soot. On the left side of the pan is what was going up the chimmy pipe, just a black soot. by tapping on the pipe alittle came out.
I think I will be good for burning for the rest of this season before having to clean the chimmy out with a good chimmy sweep brushing.
Back to heating the shop and house.

Looking good mr Bob, you’re “hooked” now, nothing like heating with wood, hypnotic, watching the flaming wood, in the cosy heat.
Your observations about vertical versus horizontal wood reminds me when i was young and sleeping in a hunting cabin, the old Husqvarna coal/coke stove top fed, slender type loaded with small, standing wood, became almost glowing yellow, the radiating heat burned when i slept on the floor, had to turn the to the other side every 15 minutes, to get “evenly roasted”
