Everything good. And you added a few more gizmos you never told us about. The diff-pressure meter for example. I like it.

Im thinkingā¦ its a known fact with charcoal gasifiers that they are slow to start if they have been lit and let fully cooled down. Some, like Koen, dump the charcoal out after each run and fill in āvirginā charcoal.
Reason is most likely that at operation, charcoal starts to recristalise in to graphite due to extreme heat, wich is less reactive. You can test this with electricity, virgin charcoal is much less conductive, if at all.
A nother example is gunpowder char. Fastest burning charcoal is obtained at low baking temperatures.
Jan, in your case, when you shut down the gasifier, the residual heat still bakes the wood, making you new fresh charcoal for the next day, and right at the nozzles.

Thanks for the explanation Kristijan.
That should explain why I get worse gas in a 2 start of the day.
Do you have any tips on how I can avoid burning a hole through the charcoal down to the grate?
Surely that must be whatās happening because I get hotter and worse gas earlier, when I drive on spruce bits?

Does this happen when you let it cool?

No, after a few days when I run on spruce and the unit starts to get denser, the temperature of the gas rises and the quality of the gas gets worse.

Ah, thats probably because spruce charcoal is soft and britle. Over time, dust and small peaces will fill up the voids between charcoal peaces, inhibiting gasflow. That part of the charbed is now dead. Esentialy, your gasifier became smaller (less active char volume) and you start overpulling it.
Solution is to set the grate just right so that it slips just the right amount of char. Keep the dust filled char constantly moving downwards. But not too much, or you risk emptying the charbed and raw wood falling too low

Ok, then I lost myself again when I reduced the holes in the grate, the last time I changed the grate.

Do you have a dangling grate? I found relatively litle char slips trugh the actual holes, but more on the side of the grate when it moves. Therefore adjusting char slip is easy, just adjust the height.

Exacly what you describes about charcoal is explained by Torsten KƤlle (inventor of KƤlle gasifier) in the KƤlle gasifier you use the grid where gas passes out, to crush and grind the charcoal next to nozzle, these gasifiers was known for extremely fast startup (less than 30 seconds).
Im going to see if i can find some of this text and maybe translate some of it.

No, I have a 3-part grate that is on top of 2 metal bars, which are welded to the side of the lower part of the unit, then it more or less fixed.

The charcoal sliping off the grate is very important like what Kristijan said it is going to the side of the grate pop corn side and larger. Lots of holes in the grate for ashes and very small char pieces to fall through too. Making it shakeable is important like the hanging from heavy duty chains on WK gasifier. Mine slips charcoal and it is about a 1" gap between the grate and gasifier bottom. Some people have it set at 1 1/2" . A flat grate with no bowl shape is better so the charcoal can just slide off from the gases passing over and through the holes of the grate. This happens when you start to plugging up at the grate, it will purge itself when you step on the gas pedel. I do not mind if it slips a little more charcoal because I just reuse it after screening it. It is kinda like a retort for making charcoal. It is a good size for a charcoal gasifier fuel.

Thatās probably a good tip, Iāve been trying to get out towards the edges with my roster, may try to look at this if it continues to get tight this fast.

Jan, a good poking technique can also help some. Beat those dust pockets up while the gasifier is being sucked.

Jan you say you have a fixed grate?
I think Tom Collins had similar issues.
A swinging or rotating grate would be best, but Tom loosened his grate up at the time to let it vibrate more.

How fast do you normally go in the S10? 100km/h?

No, 80-90 km is enough on my small roads, itās almost only 80 km on all roads around here.
100km on the road to BorlƤnge (up to JO) double driving field.
