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.
