Historic woodgas tractors




some post up i wondered how the “dux” gasifier is built inside…
this seems to be the solution…it is a copy of the french gasifier from the gasifier developer barbier…has a heat exchanger where the hot gas pipe goes through water and produces steam…the steam is sucked in with primary air through a grate near the bottom in the glowing coal…
pictures found in the french forums some post up…

göran, i have bought a little welder , one of the very simple old ones for 220 volt and tried it with the honda genset on charcoal…works fine, but for now is only for emergency situations, if the batteries are not good more…with the batteries is more quiet…
the last gasifier with the watercooled nozzle on the motorcultivator is also thought for the genset, i observed, when i must make meatcutting in winter with the genset because of lack of sunpower, the nozzle of the stationary unit becomes a bit stressed because of the high rpm of the genset ( 3 kw on gasoline) honda engine…

What is wrong with how he hauling the hay, Wayne K. hauls his hay the same way.

Ha ha, but Wayne doesn’t use a Imbert gasifier, with double walls, and heat all the way up, imagine this hayload catch fire in traffic, a little wind, and a driver that don’t look to often in the rear-wiew mirrors (if he had any?) :grin:
Edit: i just saw he had rear wiew mirrors, and proper ones by the time.

Durning the scond war with fire and bombs blowing up around , just can’t sweat the small stuff back then. But now? Yes he should have a better shielding barrier around it to be hauling hay where you live.
