Why is a heavy stove an inefficient stove? A tall combustion chamber makes a lot of draft to keep a fire roaring, how can that be a bad thing? What is TARP-V and how will it improve your stove? Dean Still has the answers for you in the latest Rocket Stove 2020 Video.
Here is the Ten Stove Design Principles poster. Many more helpful documents are also linked on the Publications page.
Hi Dean, Good to see your interactive video with good explanations of the principles of good Rocket Stove design (Thanks..!). It seemed to me after hearing of the short dwell time that lengthening the stove (upwards…) would help, but then I hear you say that could draw in too much cool air and reduce the temp of combustion… alas… a step backwards. But could you just reduce draft with an intake damper, to reduce the cooling, and control & optimize the draft. Still other aspects of ‘TARP V’ could counteract the benefit.
How about a tall conical pot, specific for Rocket Stoves (thanks Larry W..!) such that there’s greater vertical dwell distance, there’s temperature (of course), there’s lots of Area along the long conical wall, there’s some close proximity radiation but mostly to a small ‘patch’ at the bottom of the conical pan but there’s also radiation along the sides of the pan once the ‘ceramic’ hits temp, and there’s velocity due to the relatively tight fit of the pot to the ‘conical rocket’ … stove and the vertical rocket ‘shaft’..(controlled velocity). Sounds like a military design… sort of.. NOT (let’s keep our people safe and keep ‘THEM’ safe too, so we all fear-less.). Seems plausible, if a bit odd… I love the word plausible.. it’s so hopeful in a troubled world… Yours, Newt
