A new project for the new year, a rocket stove!
I’d like to build a rocket stove in a greenhouse with a batch box. So, the testing begins. The basic design is drawn from Peterburg Batch Box Dimensions and my working knowledge.
It’s only got a 4” riser and with the box being 9” x 11.5” x 5.75” super small. That’s not much difference than just a standard J tube size. The P channel taller than it should be and there is no funnel for ash.
Let’s fire it up and see what happens! The original design for the chimney was just not going to work so I improvised some with some 8″ stove exhaust. Of course it smoked like crazy until things heated up.
This thing is on fire, where’s the smoke? Oh yeah, it’s a rocket stove.
Yup, I’ts burning. Cooking even.
It works! I am impressed to see that the torus down the tube in the base of the chimney. The small box burned up the fuel pretty quickly. The next build will be a bigger design, built for a 6″ chimney. Since the limiting factor on box size is width of a brick that will as big as I can build with what I’ve got. Eventually I’ll need to get some alternative materials to build bigger boxes. Then perhaps a larger one and clay slip to seal things up?
This will be great to show off at the GLPDC 2017 design course near Ann Arbor, MI!
