Hi All


I am kees from Holland, I am interested in technologie, i do electronics as a hobby, most highen end hybrides, I like to experiment with wood fire, I see a
lot of people join the new thinking of a durable world, nice to see that, I do make high end amps also with old audio valves and modern mosfets, even think
about a electric car, buying a induction motor of 20 kW and rewind it 4 pole.

For now I did testing a rocket mass heater setup see link.



I have to say mine nabure do call the police when I do this as on the picture cleaming smoke in the home, impossible, no smoke, but she
do not like me and that is the reason.

I hear a batch rocket is a better way for in the home? what do you here advice, a batch rocket is not much more complicated and I have a co2 welder
so no problem.

regards

Thanks for the link, I have done write him.

I have now put a oil drum over the riser, did see the thing smokes, maybe because of wind, it is outside do disturb the burning a lot, also the bricks
are concrete street stones, maybe fire cools down to much, it take a while before the bricks get warm.

Hi All


I have made a rocket cooker, but it does not well, special outside and wind do blow things out of working, smoke.


I have seen some on the internet, I think I need to isolate the riser also, I had ceramic blanked but these I do not use
to dangerous uust, did trow it away, I need other kind of insulation.

Some tips maybe to rebuild it? like the feed can be diferent maybe, I have a heated air part in it, does work, but I get draft
problems, maybe maing a extern air input and close the feed after laoding some wood.

The tube is 9 x 9 cm. I did use the 1;2;4 rule.

regards

I think people here will say that what you have built is not a rocket stove cooker because you lack insulation.  Ceramic fibre blanket needs to be encapsulated I think if you are going to use it for cooking.  So you could have kept it instead of throwing it away.

So, without insulation the riser isn't getting hot enough and you're getting smoke.

Thanks for advice, yes that was what I have also think, there are difference insolation ways, I have the blanked still in the trashbox, so can recover it but how dangerous is if when inhaling
it like asbestos? I do protect myself, I need a shelf around the riser after put that stuff around.

I go chabnge some things, making the feed longer, and put a cap on, make lower input for the air coming in is I think better because wind does disturb the burn also. Also I need to keep the feed cooler
otherwise it get competative with the riser, we need here good difference in temp.

I can buy thin sheet and make a box where the blanked can be enclosed in against the dust.

Hi Kees

Maybe you can get some wind protection boards to make smaller cooking "room" outside? Atleast on some directions.

Metal is going to last long I guess.. I have read it so many times on this forum. Since almost every body tries it at first.

For it is only a test, but I think I go different because the heavy metal does to long to heat up fast, what I go search now is sqaure sheet 0.2 think and
put insolating vermiculite inside it, it will insolate perfectly and weight is low.

Would you turn that thing down? I'm controlling a mind here! Look ... look at the tiny ad ...
