Making my simple fire gasifier

[BrianAltEnergy (Brian Madera)]

I got impatient and tested the gasifier for leaks and didn’t find any so I filled it back up with charcoal and run the generator until it shut off.

Used almost half the tank of charcoal so it probably either got too much of a burnt pocket of charcoal or it just didn’t have enough charcoal above the nozzle to produce good gas.

EDIT: Just going to slip this in:

Hi Jacob, I ran a 7hp Briggs genset on charcoal. It was based on Koen’s stuff. I found that I needed 24 inches from the nozzle up to the surface of the char. When the char got down to 24 inches it would shut off like a light switch. I didn’t like the water filter. I ended up reversing the flow and putting four socks over the discharge.

The gasifier was really hot so it was probably time to shut it off anyway but I got most of my new filter welded up using charcoal to fuel the generator.

I was cutting the pipe for to outlet of the filter when the generator quit. I fired it back up on gasoline to finish the last couple cuts and to make sure the generator was still going to run and to flush out anything I might have put in it using charcoal gas.

I expect there to be leaks in the filter because the generator running on charcoal doesn’t run the welder as good as it does when running on gasoline but this will need some form of gasket to seal the two pieces back together so shouldn’t be a problem.

I didn’t time this run but I run it pretty long and was pushing it pretty hard most of the time running the welder and my gasoline gage still shows full.
