Hi everybody, I am new to these pages, I am trying to build a rocket stove hot plate.
I have built a 6” fire box and heat riser useing 1400c refactory and a vibrating table.
The stove will be placed in the centre of my out door party house and the chimney vented straight out of the roof.
I don’t really need any mass heating, just a very hot - hot plate!
My heat riser is 32” long or 40” from the bottom of the fire box.
What would be the most effective distance from the heat riser top to the underneath of the 3/8” x 24” steel hot plate?
edit how do I load a picture from my iPad, I can see the icon but the pics don’t appear!?

Hi martyn, The forums own picture hosting is full so you now have to upload your images somewhere else and link to them from here.
Beware Photobucket, it's a scam now, after you've posted so many pictures they all stop working unless you pay them $400 a year.
imgur.com/ seems to be the most popular and reliable site for free picture hosting that allows 3rd party linking.

Hmm nobody?
Ok I have read many times about useing a formula to set the gap but I wondered if that was more based on feeding the exhaust gases a long way rather than heating steel?
I guesse I will have to experiment.

I would say what I have learned is better than a formula is to burn the stove and leave the gap as an adjustable part and move it until you find just what you like and what the stove does best with. This way you don't finish it and plaster it nicely or what ever you do and then realize its not quite right, or worse it doesnt work at all.

Yes I will do some experimenting, I just need a starting point...4” sounds like a good place to begin.
To be honest I have already had to modify the system as I found my original heat riser was to short - or at least it worked a lot better with a further 8” extension!
That meant I had to dig out the concrete base and sink the fire box down 8” so it would fit under my barrel.
Anyway I burnt the paint off my new barrel, that is a horrible job!
Hopefully I will get everything reinstated tomorrow.....

Love it. Thanks for sharing. I'm working on something related and will share when I finish. What thickness steel? Weight? What's the material under that?

Hi James, I am just making it up as I go along!
I will get a some more experimenting done over the weekend and see if I can get a good setting.
I have a few bits of steel lying around that I can play with.....

I have a question about how safe is it to release the heat riser exhaust gasses directly into my out door party room? Since I made this short vid, I have cut a hole directly above the heatriser, I did this so so I can place a wok directly over the hole. So while the hole is exposed all the gasses are going directly into the room space, is this a problem? m.youtube.com/watch?v=LCyAS4XHR5Y |

Simple answer, yes. You are flooding an enclosed space with co2 and not a little co. Very dangerous. Make a plate to go over when not work burning

Yes is does seem obvious, I will be carful.
I actually have a piece of glass to go over the hole, it is from a wood burning stove door, seems to be holding up so far!

I like it great job!
could you make that hood over it functional with the chimney? then the hot gasses(for the most part) would rise up and out of your hut. it mite need to be a bit bigger though and have a damper.

Hi mudder, I am learning and developing the stove as I go along, I have made an extension to the feed box, fitted a glass lid to the feed box and I now have a controllable air flow. I have made a secondary air intel .. P channel... .
I have other ideas to put in place including work on the chimney configuration.
It’s all good fun so far.....
