Rocket Stove second attempt

[chip]

Having a second crack at a rocket stove, I'm thinking of changing the top slightly so the pans not completely covering it but this is how far ive got.

The pans need to be clear of the top by about 13mm, it allows the stove to draw.

I use old extinguisher brackets on top of mine.

@JOEPRO i dont need to do the rocket stove post already exists

Rocket Stove

I made my first rocket stove today. Dead easy to make and a great project for welders of all experience. I'll give it a test run later and post more pics.

lower your feed box or higher your hotplate area

as the damn thing can flow towards the feed entrance therefore becoming a chimney itself

fit a door on it makes it even better

as ive noticed the higher part theres no proper way for the fumes to escape if you was to fill up that top area with a large pan

a cross section above allows this to happen but if you allowed the tube to be the mass of exhaust hitting the pan area a simple surround protects the flames from being blown around whilst also allowing the exhaust to drop at teh sides giving full rocket stove effect at the hotplate area

Thanks pal. yeah a chap messaged yesterday saying the same thing,complete oversight on my part,I think i'll just run something from the corners to fix that

Thanks gaz, i will have to chop it out as its now fully welded,its in at a 45 do you have a precise angle in mind I should set it at? edited, ahh did you mean shorten the feeder? .send me your youtube link

at 45 degrees the wood dosnt slide down properly

but your more than welcome to try it out for yourself

i had to put some holes in the loader so the smoke sucked down hence why its black

also note mine is a bigger firebox

take note of the smoke coming out of it and also the flame as well as the firebox does act like a chimney

the secondary air is underneath it and is preheated only needs 1 inch under it so makes the top even hotter

my wood sticks loadings are 10-12" so that was the length of firebox needed

with your top added on it should draw enough but you can have smoke and fire back at you when you open the door unless you face the feed entrance into the wind
i prefer the door on 1 to stop the wood from spitting as it does and also to allow the secondary air to pull underneath much better

my advice try it and learn before you trim it down im only advising you so you can see it

That works well Gazyou've given me a bit to think on.

that one failed due to that i used the wrong flue as i had 80-90mm 5mm box section instead of 4" x 3mm

but ive played with the rocket stove designs enough so have learnt a few things though you can still make mistakes on them you just have to figure out why

there is other builds on the same channel and yes i have made some mistakes even built one tried it out and its a total fail so cant use it as i lost the smokeless effect that they have

i have the boiler version with a few different builds ive been playing with

if you take a look at the 2nd vid on the above link

this is all you need for your pans to go onto, if you want to block the wind just put a circle around the cross

3mm is ample enough as most of the heat will be at the 5mm cross pieces so should wear out at the same time

if you build this type then you can keep your feed chamber higher as you have more chimney
