That’s a good thing to consider, thank you for sharing that note Giorgio. @sbowman has some wool I mailed to him so perhaps it will be a useful tip as well.
It is almost shearing time again, I think I’ll have another 3 big bags of wool and I haven’t even touched the first bags that I was given by a cousin.
Do you find that you have to add more oils to the wool if you re-used it after washing, or will the moisture be enough to assist in filtering?
cody, i wash the wool only with water, so the natural grease of the wool should not go away, i hope, though ash in it with water makes a bit detergent.
on small moveable engines the filter volume is restricted, otherwise becomes too bulky, so i look for a system to keep the filter a bit umid for best possible dust catching.
easiest would be watering the coal a bit, if the coal is very dry…but too much water makes a mess than in the system.
a thought would also be to add a bit steam , produced from water cooled nozzle or by exhaust heat, in the gas stream only to keep the filter material a bit umid.
when primary air and secondary air is very dry the filter material becomes also too dry, though it was sprayed a bit with water in beginning…the warm gas brings the umidity away…
therefore a continous source of a low humidity adding would be interessant.
on the black surface of my final filter (from irrigation system ) is very good to see if fine dust is coming through there or not…
Hi Giorgio, maybe a drip oiler in the gas stream before the filter would work, filled with water, and maybe one drip/minute?
Giorgio, our gasification systems themselves lead us in the direction of optimization, … charcoal with the correct dosage of superheated steam mixed with equally superheated air gives a very good and strong gas, but how to properly dose the water vapor???
If we approach the problem systematically and say that we want a strong, slightly humid gas at the filter outlet, this means that:
-we must correctly dose the water vapor into the gasification process at the beginning
-we measure the humidity at the filter outlet
I do not want complicated electronic regulators, only simple mechanical solutions are suitable,…
It is known that “classic” air humidity meters used horsehair as a base, which expands and contracts depending on the relative air humidity, so I could also use this property for this purpose, where I would close the water vapor supply when humidity increases, and open it when the air is drier,…
Best regards, thank you for all your posts
Cody,
I did finally add the sheep’s wool to my filter, but haven’t driven the car enough since to make any judgements. I usually try to keep things dry to minimize rust, but perhaps I should rethink that in light of improved filtration.
One thing you could do to prevent rust is get some spray paint, with the rust converter type as the primer and stove paint as the top coat. Maybe at the next service interval. Cerakote makes an Air Cure version of their very tough coating but you need a paint gun to use it.
Cody,
And then there is also my fear that moist gas will create more concrete in the carburetor. Of course if I can eliminate all dust, the moisture won’t matter so much.
