My name is Emmanuel, I am a final year student in Electronics Engineering and I am working on an efficiency of a stove. Please I would appreciate if someone can help me with how I can control the air flow in my stove ?
what about an electrical fan in the exhaust opening, at the very end of the flue pipe where the gas is cold? An Oxygen sensor could control the rotation speed of the fan. The fan can also solve the problems with horizontal exhausts discussed in this forum.
See e.g. Ericas answer in: http://www.permies.com/t/27052/rocket-stoves/external-chimney-RMH
Ok, you need electrical current for the fan, that's not nice, but perhaps it is possible to produce it with thermocouples so you do not depend on any delivery of electricity. You are an electrical engineer, if you have any practical ideas please tell us.
Peter Peterson : Bravo ! Short, sweet to the point, and Useful! Not even that far outside the box, Emmanuel can explore how much electricity would be needed for an already
running fan, (spun over with a finger 1st !) and the amount of Electrical Energy that various heat harvesting devices can supply !
It sounds like his professor is more interesting in seeing those links that follow the words of another poet, the saddest words of tongue, or pen, are these ;'' it might have been''
After all, it is in those areas that much of our hope for the future lie, 'the almosts' and the 'close only counts in horseshoes', with a small shift in efficiencies making yesterdays
problems - tomorrows grand solutions !
Because I am not the Prof in Emmanuels class, the best I can do here is an Apple ! Big AL
