Anyone have any good plans for masonry stove with a "Rocket" comustion chamber? Like this one:

There's a whole cottage industry around designing & building rocket stoves for space heating, cooking etc. Some are hare-brained & scary, others pretty reasonable. A good starting point for ideas that might suit your application is here:

Dana 1; thanks , I have already been there,I helped build the one in the photo. I thought maybe someone had a tried and true plan, actually the one we did is pretty amazing. The hot part of the top can get over 700 degrees and you can still touch the single wall flue that was only about 140. Extremely simple and efficient

Our mission team built 11 stoves in El Paraiso , Honduras for the needy. The stove use 75% less wood

Nice job cmkavala, that's a great idea for a project
