my question being, is there a optimum distance in the burn chamber, from the end of the "flameage" (whatever the fuel) to the 90degree transition into the insulated heatriser in the rmh

hey there big al
and so that piece of grit that can plug a nozzle is eliminated by the fact that the oil flows over the outside of the ball in a very consistent thickness, due to some arcane law of physics written long before the war between the states.... the only filtering I do to the oil is 1/16" hardware cloth ahead of my bulk transfer pump. followed by a month or two of undisturbed settling,
only compressed air is passing thru the .040mm "nozzle" in my b/ball thus ripping a very fine mist off the skin of oil flowing over the ball. the three degrees above horizontal is only there for the fact that I didn't drill the hole straight / horizontal. have a look at the spout of stuff above a whales blow hole, it ain't whale snot man, that is sea water bro, the blast of air from the blow hole rips sea water from the whales skin. I wonder how high a starfish would fly if it were in the over that hole when......

alan go for it
the geet system is fascinating !! oh if we could crack it to pure plasma. if it doesn't work is the prime time to open source it, there are some truly gifted garage imagineers and experimenters out here in cyberspace. I for one will follow your progress, trials, and tribulations. but there again I would have to spend more time preparing the oil, then what to do with all that nasty suspended in the wmo, for now I just burn it too, after all its just unburnt fuel.

for the bast 3 years i have been tailoring and tweaking a babington ball furnace. it is the ugliest damn thing you ever seen. the heat out put is stellar. now, having discovered the rocket mass heater and after building a stack of bricks burning junk wood to prove the theory, i am moving on to firing the stack of bricks with a babington ball.

one of my challenges in the past was pulling too much heat off the burn too soon and creating soot buildup. this insulated heat riser in the rocket mass heater is going to make my world a much nicer place.

so now, on to the invitation for input, experience...

has anyone experimented with the length of the burn chamber in relation to the length of the "flamage", be it wood or something else flammable? at the present the babington ball "flamage" is about 14 to 16 inches. a beautiful dragon's breath geyser of fire shooting out about 3 degrees up from horizontal

i am thinking of 4-6 inches of burn tunnel past the end of the "flamage" before the 90 degree corner into the vertical heat riser. the widest outsider diameter of the "flamage" off my b/ball fire breathing dragon is about 5", so a 6"square burn tunnel should work out bout right, into a 8" heat riser. and 8" flue system

comments please.
