metal rocket stove

well I have made a metal rocket stove out of a propane bottle, nitrogen bottle, and 6 inch well casing. feed tube is 6x6x16 inches long , 1st burn chamber 5 3/8 inch nitrogen bottle 19 inches long, second chamber 30 inches tall same nitrogen bottle and the shell propane bottle with a 6 inch well casing outlet. now mind you that this burn chamber nitrogen bottle is 3/4 thick steel and it gets red hot is it going to melt on me??? this thing rips must of got lucky building it, the dimensions are almost perfect. thanks rich

Rich, after a while it will die. Tho, 3/4 is pretty thick, and will last a while. Have you insulated the burn tunel and heat riser? The bottom of the feed tube?

It will start by spalling, then you'll find pieces of metal when you clean it. If well insulated, it might melt too. If not insulated, it's not a rocket yet


Thoses metal stoves can be amazing, because the red (orange may be even yellow) hot metal is like a catalyser on the gases. It's a shame it doesn't last. Tho, i'm at the stage where i can make the end of the batch box and beggining of the heat riser of a batch rocket, made out of fireclay!



It doesn't show in it's full glory, because of the infrared filter. But it was bright orange.

Have you built a rocket stove (cooking usually) or a rocket mass heater (space heating) ?

If the metal is encased in clay, it will fail sooner since the surface can't shed heat as fast. Run the fire too "rich" and soon the steel will be "melton".

Wikipedia has a very interesting and instructive Article on " High Temperature Hydrogen Attack ", explaining how iron and steel fail in this application, just touching
on why Heat treating these metals before and after are so Important !

Finally, because of the Vast Amount of Stinking Crap on U-Tube of 'Flaming Units of Death' some poster calls a Rocket Stove, I want to personally request that you
take whatever you find on U-Tube with caution and skepticism ! 4 Months from now there will be a new crop of Frankin-Clones of todays 'units of flaming death',
and they are all doomed, at which time the original poster will have long since grown tired of his balky, unusable creation, and has moved on, chasing the next
Shinny Bauble !
