Drawing a gasifier diagram is one thing, making it is another… well, I’m making slow progress… this shiny piece will allow fresh air to flow to the lower holes, it will be heated by hot wood gas on one side, and by a jacket with exhaust gases on the other, I assume it will enter the hot zone housing quite hot.

A nice build Tone, looking forward to more building pic’s 
Have you told us where this shiny gasifier is to be mounted?
I probably have forgot…
D*mn, all your builds are making me wanna build a gasifier again… but i have one that needs more work… and one waiting for repair… and a more than 100 years old chainsaw distracting me…

Thanks Goran, I intend to test install this gasifier on Fergi, the external dimensions are similar, but it will be much heavier because it is made of thicker metal (3mm). Hmm pictures, I managed to do something small today:
Here I pulled out a little of the sheet metal for heating with exhaust gases
I installed the air intake shroud and welded the exhaust passage, well, welding the bottom part will wait until tomorrow.

I was thinking it looked more like a turbo… with the fergie and Tone’s mad skills. I think it will end up something like the green monster.

Makes we wish we had the design for this.

Powell Gas Producer
The Powell Gas Producer came into its own with the advent of petrol rationing, which was introduced in Australia in July 1940. The petrol rationing was severe, restricting private motorists to about 40 miles per week. This was well before the days of Australia’s Bass Strait oil fields. Australia relied fully on imported fuel.
The unit burns wood, coal or briquettes to produce a gas to repla of petrol and thus power the engines.
Ford Australia worked with the University of Melbourne, the Vacuum Oil Co (later to become Mobil), Shell Oil Company, and the Powell Gas Producer Co to develop an efficient gas producer who would not gum up the engine with tar or cause excessive wear because of too many dust particles.
The result was a highly efficient version of the Powell Gas Producer (built in Perth, Western Australia). Ford began mass production and fitting to new vehicles plus selling as after-market units to fit existing vehicles.
The Producer features several safety mechanisms that prevent dangerous levels of gas buildup during operation. It also removes all residual condensate from the system. Furthermore, with its advanced combustion control technology, this device provides maximum efficiency while eliminating unnecessary fuel wastage.
Too bad they aren’t on the “extras” list of new cars today. There were several gas producer manufacturers in Australia, Electrolux being one of them.

The afternoon goes by quickly when you are busy assembling the gasifier, I patched the holes in the outer casing, through which the water heating coils, sanitary water connections and electric heater were installed,… there were about 10 openings. Then I made a cutout for filling the wood and prepared some parts for the lid, I will try to make a seal without a gasket,…
