As I mentioned before, Dr Larry came back to AL with us to work on some projects here. He and Jakob have been working on this gasifier for three days.
I mostly just threw in a couple ideas and did a litttle welding for them here and there. We had 3 big trainings here this week so I have been busy with other things.
They made good gas on Sat and were converting wood very nicely. Needs some condensors yet to get some more water out, and probably a cyclone before we try it on an engine.
They seem to be getting the tar out pretty well.
We’ve been using Jakobs tractor cyclone and blowers and flare to test it.
Some may have seen the nozzle at Argos 2017. Larry had it there and we put it in a little make-shift charcoal gasifier. We are using the same nozzle for this one. It seems to keep the heat in the center of the barrel and charcoal insulates and protects the inner barrel from heat, so the idea is to not have to use a big heavy fire tube. We’ll see what happens as we go. We may have to line it with a sheet of stainless or something. …We’ll see. Stay tuned.
Jesse is a better public speaker than he is a photographer, we’ll try to get some better pics as things progress.
Yay, …Made a condenser plate today and added some holes to the inner barrel for more transfer to the outter barrel. Also found that Jakob’s non-drained blower pipe had filled with condensate and made it drain. Also, getting water in the hay filter. Made beautiful burning gas. Could find no tar.
Does anyone have a test for tar.? I mean other than stuck valves.?
We ran it through a micro fibr cloth. Then we ran the gas onto a cold pie tin for a long time to see if we could condense anything out. Found nothing except aq little water vapor, but I still want to put in some kind of cooling rail and maybe another cyclone before I risk an engine.
But it flares very well. Can’t see it well in the pics in the daylight I guess. But you can measure the big goofy grins.
Good metalworking…can see…
Good morning Billy , Looks like yall are going wide open .
The gas should be clear or maybe hazy. You don’t want to see a lot of smoke .
Regarding tar testing----
This may get you started:
SWEM NOTHING like building your own unit and getting your welding skills fine tuned, I know the cooling rack will help keep the water out of the motor, and a good size media filter helps more yet, hence why they are used, though they keep the gooie soot too a minimum too. Wayne allso has a youtube vidio that he checks his gas pedle for sticking plates after cooling down some…Back when i was about 16 years old driveing around town i seen a truck smokeing heavy and it smelt like wood burning, so i followed him tell he pulled in a parking lot at a resterant, as he went in too order some food he left his truck running, he told me what he had for fuel, and that his wood was a little too wet and wood need too stay running till he gets home, he probbly switched over too dino after got home too dry out the tarry gas before he shut down for the night. PS Allso you might have a broken spring the sise of a valve spring or smaller if its like chevys that have been known too brake that stop things from working, just under or arou d the valve body, check a dodge tranny book under trouble shooring or look around the valve body in the book. Thats why its best too have a core tranny, parts swaping that dont coom in the standard seals gaskets and clutch kits.
Hey Pete, thanks for the info. I hadn’t had a chance to glance at the link until now. ANd I still haven’t had a chance to really dig into it. But it looks like it may be what I was looking for. Thanks.
