| My rocket heater is based very heavily on plans by T2H with modification to the secondary air intake shown by PPotty1. The stove is made from 4 inch box section mild steel and is 13 inches long by 16 inches high. The vortex generator and riser tube are 2.75 inch stainless steel and the exhaust is 3 inch tube. Pictures show the various parts and a video will follow showing the stove in action. Measured temperature at the top of the riser/heat exchanger is 800f with the a fire box temp of 700f. The secondary air intake feeds to a 1/2 inch inlet which enters the vortex generator about two thirds the way up. Comments whether negative or positive will be welcomed. | |

| nice build there
however i would have put the vortex tube at the back reason for it as you want the heat more at the front than at the back like you might have via the build you have
you can also try a kettle boil test as well | |

| Thanks for suggestion re riser tube placement which will be implemented in the next build!
At the moment I am investigating more secondary air inlets and their effect on gas temperature exiting the riser tube as well as cleaner burns.. Stove is difficult to get going but once it "rockets" it is away so hoping more secondary air will help.
Any ideas or comments on this welcomed. | |

| Nice looking stove, if you can would be nice to see what kind of temps you are getting.
Congratz on your finished build! | |

| I have now added another secondary air feed through an internal half inch tube running through the firebox to the vortex generator. First impressions are that the vortex is more turbulent although no increase in temperature seems to have occurred which has surprised me. Also the stove is now more controllable as the airflow into the fire seems to have been reduced resulting in a gentler burn. Not the result that I was expecting!
Any comments or suggestions appreciated. | |
