Using a metal gasifier to run a metal generator using chips made of wood, not metal
I have been feeding woodgas from my Chinese JXQ-10 gasifier into my Onan
6.5NH genset on and off this summer, in an attempt to figure out how to reliably convert wood chips to electricity. I'm getting closer, but I ain't all the way there yet. Don't tell anybody, but I have been feeding the genset some pretty tarry carbon monoxide and hydrogen gas. But so far, the engine still runs fine. If you have nothing else to do, you can see my log of this summer's related events at: http://www.spaco.org/JXQ10A.htm Pete Stanaitis ------------- |

I put a like on your video, nice

A valid point, Jim.
After each engine run on woodgas, I switch back to gasoline for at least 10 minutes. I am hoping this will keep things clean enough for now. I have lots to do in the next few months to get ready to go at again in the spring. One of the main projects is to make a final filter out of a nice 5 or 6 gallon steel barrel that has a clamp-on lid. It'll be filled with wood shavings and mounted in the cool end of the gas stream, just before the engine. But the MAIN project is the reduce the diameter of the grate area in the gasifier so I can get the "below grate" gas temperature up from the current max of about 600°F to at least 1000°F. That will get rid of almost all the tar. To support these and other changes, I will rebuild my Arduino-based datalogger, adding more pressure sensors so I can directly monitor pressure drop across the new filter and a few other things. I will also add some "traffic lights" to tell me, at a glance, if I am in the "sweet spots" for grate temp and suction. I may even start to make the datalogger into an actual process controller by adding a servo to adjust the fuel gas mixture.
