I have pretty much decided what I am going to build, but have a few final questions. If anyone can help, I'd be really grateful.
I am hoping to construct a rocket stove heating two hot plates, one dire3ctly over the heat, the other on the left and thus slightly cooler. Both plates will be sealed and the exhaust will then travel up a chimney and away.
I am thinking of building a thermal block stove and insulating with sand. Then building in brick around it to finish off, support hot plates, chimney, etc.
I was going to use stainless steel flue fittings for the sctual stove, combustion chamber, etc, but it is really expensive, so I thought I would try and build it from thermal bricks. My questions are:
1. Is there an ideal length of pipe where you put the fuel/ air intake, before it reaches the elbow?
2. Also is there an ideal length between burning chamber and hot plate?
3. Is the diameter of the tube important? I would like to do one of about nine inches.
4. Is the inside of the tube better smooth or rough. I can sand the bricks I'm using so they are really smooth if necessary.
5. Any other comments and suggestions extremely welcome.
Wink, wink, nudge, nudge, say no more ...
