JanA. yes, please of keep posting up your woodgasing activities.
On this topic you picture up well how you have rust you must deal with. And what you’ve done.
On others of your topics you showed accumulated intake soot deposits.
Considered normal for WK builders/users. You however decided to go like other European fellows have with a hot fine screened pleated filter. A choice.
And on at least two of your topics you picture up show your in-use upper hopper conditions.
Black gooey and dripping is normal for a raw wood gasifer.
But I’ve tried to help neat-freaks with woodgasifiaction and they could never accept, black and gooey in the upper end as normal. Actually desirable; showing heat refining out of for removal of the long chain creosotes. The surface build ups then actually acting as a steel metal preserver from the acid conditions.
Ha! neat-freaks I’ve known could never accept the “baby diapers” mess of a working woodgasifer. Expecting the clean, clean conditions of using refined, filtered and dewatered natural gas or liquid petroleum gas. I’ve wondered?? Do they have children? Or just have the woman handle that end of keeping a baby clean and smelling nice?
And your systems show it does not have to be all pretty shiny SS to have a useable working gasifier.
JohanM. here is your guideline on what you can show and not show:

This is an open side many pictures topic.
Embedded in one of the last post WayneK. put up a link to his Premium side internal building up of his downsized unit.
So your example of what you can show. And are asked, not to show.
JanA. as AdminChris recently posted up the WK is a large internal volume charcoal bed system operating at slow internal velocities. ( And with its air as extremely pre-heated)
The “Imberts” he said are relatively small internal volume units. With a much smaller charcoal bed. They operate at much higher internal air and gasses velocities. (The charcoal bed MUST renew itself continuously with no interruptions. The WK with a larger charcoal reserve you have time. Its developmental details are the extreme air pre-heating and systems made to preserve the metals from the metal contact killing heats.)
