We are exploring the practicality of a rectangular solid-shaped charcoal gasifier that would be an 8"x3’x3’ rectangular container that would strap on to our cubic-shaped open source micro tractor. The Microtractor has a 28 hp Briggs and Stratton 2 cylinder engine. See http://opensourceecology.org/microtractor-workshop/ .
Does anyone have any insights on what would make this work - or why this may not be a good idea? Is there any reason why rectangular-form gasifiers would not work? We would like the rectangular shape since that would fit well with our cubic open source Power Cube, which is a hydraulic power unit.
I could see one issue with the burn zone getting too hot and melting the sides of the container if the container is only 8" wide. Any suggestions? 8" wide appears to give us approximately 4 gasoline gallon equivalent (after engine derating) in terms of run time, so it’s a nice size that would make our machine practical while allowing the gasifier to take up little space. We are considering placing the gasifier on the back of the walk-behind MicroTrac.
