Jan,
“Yesterday I was delivering firewood all day (25 mile roundtrips) with Rabbit and trailer.”
DOW? A workhorse l wuld like to own…
I guess its that time of year for firewood preparation, althugh its a bit late for that here - sap is already in the wood. Althugh some customers still hire me and my father in law to do ligging for them, not knowing the beech will dry for at least a year untill its considered burneable.
About the hearth side, l am starting to get a feel why the oxy zone needs to be rather small in Imberts. Tar elimination. But l now saw a good air preheat and most of all a big enough reduction zone is what makes a good gasifier!
Althugh l hope l didnt speak too soon, still need to see what happens with ash in such a sistem.
Tom,
Sorry for the confusion. What l wanted to say is althugh there is of corse a considerable power loss, the drive characteristics are wery similar to petrol. The power is there when neaded. l think with a condensating hopper, its gonna get eaven better.
Here is a skech of my current hearth
The air gets preheated both from the woodgas and whatever heat is lost from the firetube WK style. Circulating in void, JO style
l did a video today, but for some reason, it doesent upload. Tryed 3 times.
l did all the tests today, idle, normal drive, fuel consumption, highway… for now, all looks right. Trafficlights are doable without hybriding, highway speeds are in the 90-100kmh neighbourhood, 110 is pushing it with mixed chunks. Steep long hills heat the system, as they did on the old gasifier. Fuel consumption does indeed seem to be less!
Allso, before, l was DOW with the air setting allmost all the way closed. Now, l had to drill a hole in the temporairy cooler plug to let more air in, and still drive with best power with the air setting allmost all the way open. Not sure whats the cause of that. Richer gas perhaps?
