Forest biochar rocket stove 0-2
A newer design based upon a refined design developed by Ed Revill from Swansea Biochar.
The forest stove 0-2 will, as with Eds stove, use 6 inch stainless pipe for the heat riser, but will use 8 inch stainless pipe for the combustion chamber, allowing for more fuel to be burnt
The new fuel hopper that feeds wood into the combustion chamber will also differ being 8 inch square, vertically aligned and much taller allowing for larger pieces of wood to be loaded into the hopper reducing the amount of attention that the stove will need to stay alight.
The filler hatch for the biochar production chamber will be moved from the front to one side (here the right) to make room for the fuel hopper.
CAD drawings
This time it was found to be very difficult making some of the more complex shapes using Art of Illusion
Some parts of the model were made using the freeware Design Spark Mech and exported as .stl files which were then imported into Art of Illusion for further manipulation.
STL CAD file for ForestStove 0-211 The model was slightly broken during export from Art of Illusion the hatch for filling the biochar chamber was placed away from the rest of the model
.stl files will open with FreeCAD
Forest biochar rocket stove 0-1
This is a rocket stove type design that uses wood as the insulation in the chamber around the chimney (riser/stack pipe). This wood is pyrolized by the heat of the stove and the produced gases are fed into the chimney and burnt, As air does not flow through this the wood it releases gasses and turns into biochar/charcoal rather than burning to an ash.
The stove design was based upon a design made by Edward Revill from Swansea Biochar and developed with his assistance.
See a video of Ed explaining this stove.
