Well, it was a far shot to try the washing machine grate, didnt take 5 minutes to make, but l learned something new (so a partial win l wuld say).
I followed the advice of less is more when it comes to grate area, so thats why l didnt make holes bigger. But it might help.
The restriction sits on 3 weld marks, and the loose space between the restriction plane and firetube is sealed with ash(l put in the sifted ash at cleanouts).
The nozzles were first 7". Then Max advised on smaller circle, l screwed them out to 6", thain l found some bridgeing happend with bigger fuel, so l screwed some back to 7".
Exactly! l think the future of wood gas improovements are in the turndown ratio. Were getting there slowly.
Now that l learned to poke more in the charbed to break the ash, l can idle for a long time, drive in the city, but allso drive on the highway at 110kmh for short time, then power is back to 80-90kmh. If l know 110 can be reached, l want to be able to use that ability always and for as long as l want. Thats whats eating my nerves for the past few weeks now
A post grate reduction is one solution, but agenn, when we run out of the secondayry char, party over. We need to find a way to make the charbed adjustible.
One thod is the Käle charcoal gasifier nozzle princip. It used a diafragm to push the airnozzle in and out of the oxy zone, dictated by the engines wacuum.
Or perhaps a moveing grate?
Perhaps Max is right. Perhaps there realy isnt anything new under the sun. But hey, the solar system is a big place
