Rocket pot oven

Re: Rocket pot oven

In the previous picture you can see some of the modifications I made to the stove. I put a Vent in the top of the pot and inserted another small flower pot. The aluminum foil is just to keep the hard surfaces from abusing each other. I have a spiffy handle on the door but it melted. So I just stuck a screwdriver in the hole. It works for now. You'll also see a picture here of my pizza stone having turned white I don't recall what the temperature requirement is for that. I believe it was 600+.

Re: Rocket pot oven

Okay I think it's time for an update. During a busy weekend I had another opportunity to fire up the rocket stove and try my hand at cooking more pizza. I'll give you the details in reverse order. The pizza stone actually broke. I found that the heat was enough to cook this off the pizza stone and partially off the dome on the flower pot. I'm going to have to make some modifications to retain the heat. I'm not sure what all information you care to know about. However if you have any questions feel free to send them along. The temperature inside the oven was well over 650?. That is the maximum on my little oven temperature gauge. I may have to go to the store and invest in a laser temp gauge so I can be more accurate. Fire management inside the rocket stove has been a bit tricky. If there's too much fuel it begins to smoke. I believe my burn chamber is too short and doesn't provide sufficient time for all the smoke to be consumed. At this point I am going to cut up some firebrick splits and make a new cooking surface. Step two in my plan is to insulate the dome. Probably just using Perlite or vermiculite cement mix.

Re: Rocket pot oven

I just put another thermometer in the oven and instantly I had two thermometers over 500?. There you have it 1000? plus.

You stick to helping ppl with chips on their shoulder and Ill do the jokes......

Roger,
Yes my oven is 21" internal diam. I usually remove half the coals once it's up to temp and then maintain a fire on the side, cooking 90 sec pizzas one at a time. I usually make the bases about 9" in diam. We find that pizza parties of up to 35 are really easy provided that guests share whatever comes out of the oven rather than wait for their individual pizza. We prefer this sharing method and I've done parties of up to 80, but this is getting to be a struggle cooking one at a time.I can't fit a whole pig in my oven, but I have cooked a 5 kg turkey. My oven is has about the same floor area as most domestic kitchen ovens and we feel it is perfectly adequate.
Regarding the mineral wool insulation, because it compresses quite easily you may find it difficult to do the stucco layer straight on to, compression reduces the insulation value. This only applies if you are planning to finish the oven in an igloo style. If you are making an enclosure style the mineral wool is quite suitable.

Re: Rocket pot oven

In my area lots of hardware stores have began stocking Roxul brand insulation. Roxul is a mineral wool insulation, and would work perfectly for your oven. Not sure how easy it will be to find in a warm climate, but they do use it for acoustical insulation so it is possible you may find it locally.

Re: Rocket pot oven

If you want NY you only need to hit 600 (6-7 minutes), 750-800 for NY elite 4-5 minutes), but you are going to have to have a floor of 800 and walls/ceiling over 900 for a Neapolitan (60-90 seconds).

I will still talk to you anyway, I make all three, and even Detroit style at 450 (12 minutes)!

Re: Rocket pot oven

First things first, I appreciate all the feedback. And I can take a joke as well as the next guy. So no worries about my fragile ego- I can both diagnosis and treat myself, but don't tell anyone

And apologies to Wiley, it was Al who was cracking wise about my yard

Tscarborough - Really, double the temperature, does it really need to be 1000?? Actually I found it rather easy to double my temperature. I just put another thermometer in the oven and instantly I had two thermometers over 500?. There you have it 1000? plus. Actually I did Max out one thermometer at 600+. I'm hoping to get higher than that with improvements in my design. I hope you'll talk to me even if I don't get up over 1000?.

I think I'm going to go with as small of a door as possible. Since I don't need the 63% to burn, All I really need is a chimney on top to allow the rocket to vent.
I have already experimented with blocking the inlet on the rocket to help her Serpi. The floor does cool rather quickly however I think that is in part my lack of patience and not allowing it to get fully up to Temperature.
As far as pots go I actually had two stoves in the pictures the taller pot was removed in favor of the lower dome of the same circumference. I'm hoping this reflects more heat back on to the cooking surface.
I believe I will need insulation over the pot of some sort. I attempted to find insulation for a furnace but all I could find was fiberglass. I may have to go back to perlite or vermiculite and concrete.
I think this rocket stove idea all boils down to time versus mass versus efficiency and is a plausible idea however when it comes time for me to build a permanent woodfired up and I will end up going with the old tried-and-true.
David is your oven only 21 inches internally? do you find it difficult to have space for a fire and a pizza?
I shall make one more attempt to attach multiple pictures they should demonstrate the difference between the large pot the small.
Okay that didn't work I guess this will serve as a quick picture of my lower domed pot/oven

Re: Rocket pot oven

Here's another interesting one
I assume he has the chimney come inside the dome and exhaust out of the door as well as having the pipe heat up under the floor.
Starting to get some thermal mass less heat loss etc

Re: Rocket pot oven

Well done, looks like yr cooking! Wil try putting a rocket in my wfo but it wil mostly for pre heatingand maybe keeping the temp up while doing a roast, my oven wil be a proper brick one so for sure wil not get enough heat from rocket alone but i stil believe by keeping the door closed and have the rocketstove chimne inside the floor it can be used to keep the big fire fire burning on the oven floor to keep more heat inside and not waste to much wood.

I'll say, it's not siding off the board. Neither is the glass of wine for that matter

So far so good.
