Things that make me go Huh

So I fired this puppy up tonight. Had a few issues getting going, I suspected the cross draft was not working so I punched through the partition at the top to bypass it going into the filter. I probably should have troubleshooted this a bit more. I think my fuel may not have been processed small enough and I may have been coming on too soon with the water drip I dont know. But for a good while it ran pretty stable but it dies out long before the hopper is empty. So I think too large of fuel is c…

Hi Matt, Size does matter, a lot, the upside is the ease and reliability of the system with good fuel prep. I get my best results with a spread between 3 and 12 mm (1/8 to 1/2") Sieving that is a piece of cake. The gas temperature stay’s low, the gasifier relative cool , gas stay’s dry. When you overdue the waterdrip, then your charcoal becomes moist and a pain to restart next day. I adjust waterdrip according to my load needed, with a baseline 1 drop per sec, (20 drops equals 1 ml ) = 0…

Ok yeah I can only get about 2/3 of the hopper that will run stable. So that make sense. Yeah the water drip is impressive, when I get it good and hot I can dump quite a bit of water into that thing. I think a more refined with steam flashing and automation controls could really improve this. Cheers, thank you for your input

Hi Mat do you mean injection of pressurized water vapor into the gasifier air nozzle?

Thrive Off Grid

No just steam no pressure, water drip on something that will flash it. Like engine exhaust. You dont even need to flash you can simply drip directly into the nozzle.

i built something similar on my toyota 22re pickup. the “droplets” of water volatilize on the exhaust pipe before being swallowed by the nozzle

I would like to pressurize the steam to produce a venturi effect on the air entering the nozzle (to compensate, a little, for the pressure drop of the gasifier)

[IMG_20200806_073704355] here is my source of inspiration. We can see in this drawing a nozzle for the water vapor in the axis of the air nozzle if the steam jet enters the nozzle at high speed, the air is sucked in by the venturi effect this configuration pressurizes, slightly, the air in the generator and reduces the pressure differential between the inlet and the outlet of the gasifier . What do you think ?
