I filled the gasifier up with charcoal, ashes and wood. Sort of a pre-fab woodgas ecosystem.
Lit the charcoal, closed the lid and ran the blower:
Wait and wait. Check the temporary seals for leaks. Wait some more. The smoke got thicker and thicker, and I tried lighting it:
If you can't see the flame, don't feel bad. The flame is nearly invisible in the daylight. Mostly you see a lack of smoke, and some wavy hot air. And hear a rumble of burning gas. Eventually the flare wouldn't light, because the duct tape had melted and there was too much air leaking in. I patched it up and verified that the flare worked once more. I need a better temporary seal - duck tape supposedly melts at around 130 degrees.
I really wanted to see the invisible flame, so I waited until dusk, and fired it back up:
You can see the flame much better now. It is orange-yellow, with a blue tinge at the bottom. This indicates some tar in the gas, not a good thing. But I am running it without the restriction in place, which means the fire is not as concentrated as it should be. It will get a little better once I have things finished up.
I shut off the blower for a minute. The gas is still under internal pressure, making a slow flame:
The flare in the dark:
Here's a video I put together of the gasifier in action, with some footage in the dark. Toward the end, the flare is self sustaining:
Excited yet? I sure am. Just wait till I get an engine running on this! It won't be long now...
