I’m still thinking about improving the lower part in the grill area, I don’t want complicated solutions, only simple ones come into consideration. From the first day, when I started to deal with the production of gasifiers, I like the way of the Imbert grid area the most, namely that the restriction opening continues downwards, expands and is “immersed” in the coal. Thus, the flow of gases should partially exit downwards through the grate, but mostly it would raise ash and coal dust and rise up next to the restriction tube. If I use this idea in my system, I would get an empty space at the top of the grate, which would allow the charcoal and ash content to rise up and thus loosen,… I will find out when the gasifier is next emptied.
