This is where I’ll post stuff about just my gasifier design not the filters, engine or etc.
Basically it’s an updraft producer that uses a grate. The grate makes it easyer to clean out and eliminates a clean out hatch that could leak air.
It started out as a small hole about 3/4" like a nozzle then about a 2" hole with a grate then a much larger grate area and now back to the 2" hole/grate area.
Below is a photo of the newest version. The producer is upsidedown. I’ll keep adding photos as I get the time.
