Good evening all,


Does there exist any literature on how to calculate the heating power of a batch box rocket stove, based on the dimensions of the rocket stove core and the physical properties of the fuel used?

Thanks

Good evening all,


At the moment I'm having a thinking exercise on a proof of concept on an electricity and heat generating unit based on the concept of organic rankine cycle generator.

On the last I have the following question. Does anyone here have experience whether a car AC compressor (scroll type) can be used as an expander to expand in stead of compress the refrigerant?

Does anyone here have experience on ORC units and where to find practical and theoretical knowledge?

Thanks by forehand

Hello,

Experimenting with the rmh is fun and rewarding. Congratulations with your achievement and keep experimenting!

From my limited knowledge Gained from experiments and a lot of reading: "Once the barrel goes on, the chimney must go up" Simply stated, you can build your stove 100% as per specs, without a chimney it wont work

Made my first batch of waterglas yesterday and will probably perform a small test tomorrow to try and make a fire Brick with zand and waterglas. I LL keep your informed

@Peter:

Thanks for your reply.

Check following link out:

Is this something too good to be true? If it is thrustworthy it is a damn cheap way to make your own firebricks in any shape wanted. It involves some "chemistry" and work, but should be doable...

Very curious in getting some feedback on this.

Being not very durable meaning it'll fail in short notice?

Would the same material lined with some kind of refractory hold?

I've been experimenting a lot with burn cores made from Ytong Blocks. When I did a test with a batch box core, I saw the blocks falling apart due to cracking on the inside, probably caused by the vast temperature difference between inside and outside.

I've been using the ytong blocks for their cheapness and ease of handling.

I was wondering though, if I was to line the ytong on the inside with ceramic boards like on the link below, would the system hold?

Any suggestions on cheap and durable building materials are greatly appreciated!

Hallo all,


I've been reading a lot on permies and I am fascinated by the rocket stove idea. I am experimenting a lot with building rocket cores out of Ytong blocks (AAC). I built my j-tube and tested it succesfuly. I'm building a batch box now and will test it very soon. But what might be very interesting for you guys is that I am a professional engineer, used to design stuff, draw in 3D. And I've been tackling the rocket stove core the same way. First design it in 3D, then build it, then learn from what I build and update the model. I also have a nagging idea that the technology should be used commercialy to tackle the environmental problems, caus rockets burn clean!!! I'm 100% convinced that the rocket technology can be used in commercial boiler technology, it's just a matter of redesigning in my opinion. I have absolutely no clue if anyone ever has thought about this.

To make a long story short, if you need someone to make professional drawings or something, I can always look what I can do if you guys would be interested. If you guys can help with ideas on how to get the synergy going between rocket stove technology and "outdated/polluting" current boiler technology I'd be massively thankful.

Thanks Peter for the response and clarification! I'm in the process of building a batch box core after succesfuly building a j-tube one. I'm very interested in the performance of it and I'll certainly post some video's of it burning on my youtube channel "Rocket Stove Experiments".

The reason I asked is I can't stop thinking why commercial boiiler manufacturers don't incorporate the rocket stove burner cores in their appliances...

After tinkering a lot with a j-tube, I'm turning my attention to the batch box core, as I think it is a far more practical thing. The j-tube works fine, but needs constant tinkering, so I'm gonna build a batch box following your dimensions and I'll have a look on how it performs...

I'l keep you posted

Ivo S.
