keith s elliot : Jesus Wept ! Am I understanding that the aluminum boom that you wish to re-purpose has a taper to it and therefor The four sections, each 7' long
would each individually vary in size ? I certainly would not take on this challenge if I did not have to, but your build would probably be unique !
My first assumption would be that it would be very hard to get this system to draft ! That could be planned for -so that you could pop the clean out cap off of your clean
out at the base of your chimney, put a lit candle in there to get the draw started, and warm things up a little! Then replace the clean outs cap and build a very small fire
of fine split very dry kindling and proceed from there, I expect that this would be needed about every time !
So, If you want to try this idea, try it first out doors, simulating the Thermal Mass by passing the pipes through a wooden box filled with sand for testing purposes. At
ether end you will need to create a very large manifold to channel the gases from the Rocket Mass Heaters RMHs Burner Base and then another Manifold again at the
other end to channel your Hot Exhaust Gas flow to they base of your 6'' system. I rather expect that you will lose a great deal of heat up the chimney, instead of the
150dF allowable due to Your extremely clean burning RMH, i would expect temperatures near twice that !
When putting the finishing touches on your test build, remember that you will need to have a vertical chimney several feet taller than any nearby objects as soon as
you install your barrel over the Heat Riser !
