Dear DSR 2 Lovers I'm finally about to implement this marvelous core into an cookstove. I sketched "bricked" version of it (15 cm, 6") using local brick size (230 x 114 x 65 mm) And during sketching one question has arisen: What shall be the distance of the exit port from the front brick wall? (the left one @ the image ) In Peter's setup it is 122 mm from the door. But in my case this distance is decreased almost twice due to the brick thickness (i.e. 65 mm is deducted from the original 122 ) If anyone find it of any use here is the skp file for v.8.0 sketchup

But in my case this distance is decreased almost twice due to the brick thickness (i.e. 65 mm is deducted from the original 122 ) During development at some point I shifted the exhaust port to the front of the top box, while this box was quite a bit shorter. Performance was quite the same as with the final version if I remember correctly. In your case, you need to build a stove wall above the boxes so I can imagine you have to keep some distance from the front. If possible, keep the port at the defined distance but don't be too religious about it. |

Great to hear; looking forward for pics!! Dear Peter I just realized I posted pics of my build in your DSR thread. If you think I shall move those entries to a separate topic let me know, ok? I'm posting some more. Almost dry but not yet operating at full tilt |

Jura : Do you have some more photos or a plan for this stove somewhere online ? I really like this construction, I'm planing to build something similar. Thank you !

Looks amazing Jura. I'm looking forward to more data about perforamnce/cooking.
I'm curious about batchblock design, have you considered it?
Because it doesn't need gap above 2nd port so one would have an extra 15cm of height so firebox can be higher for easier loading.

Excellent news; now, this I've been waiting!
Special appreciation for .skp - Thank you Sir.
It is getting harder and harder to have next summer without building a stove...

Jura : Do you have some more photos or a plan for this stove somewhere online ? In fact we just had a brief sketch of it and as we both work with Sketchup on a daily basis we are a bit fed up with it. So no exact sketch of this contraption is yet available. I'm planning to sketch it later on and keep ppl updated on its behavior. As to photos we had just an old smartphone with a scratched lens so they are probably not much of quality. I'll ask my friend for sending it to me I'm looking forward to more data about perforamnce/cooking. Promised. I'm a little bit sorry he did not want to install the borosilicate glass at the end of the afterburner so that we could see how was the combustion going. I'm curious about batchblock design, have you considered it? Yes, yes! I did ! I followed Yasin's developments on UZUME and his YT channel. Still the height of his batch block was over 90 cm. And My friend' wife (who will be main user of the range ) is rather short so the 82 cm height was an absolute max. she agreed to. Yup! Starting the fire in a firebox situated so low is kinda drawback, but she preferred it that way. Many solutions applied in this case were just because of some construction constraints we encountered on the way. Fumes after heating the white oven are directed to a downdraft channels placed in a wall (which serves as a heater of an adjacent bathroom). Special appreciation for .skp - Thank you Sir. Me thinks, Me does not deserve being praised with such a honorable title :-) It is getting harder and harder to have next summer without building a stove... Damn...how can one survive such a long period of time without "committing such a deed". Is this some kind of penance ;-)? Dear peterberg . Thank you very much for moving the posts. I did not want to waste your time and wanted to move them myself. Pls accept the proverbial "hat tip" |

Dear peterberg. Thank you very much for moving the posts. I did not want to waste your time and wanted to move them myself. Pls accept the proverbial "hat tip" No problem, Iam getting used to moving things around after years of moderating. You could edit your own posts for some days but not move to another thread, let alone other people's answers. Hat tip accepted, please keep the information about your recent build coming. |

I think he uses regular steel and has problem with bending so that's why he uses some type of metal grill and places it higher.
You have cast iron as it looks so in theory you could have the 82cm high cookstove with firebox placed 15cm higher.

You have cast iron as it looks so in theory you could have the 82cm high cookstove with firebox placed 15cm higher. As far as I understand the sizing of the Batchblock, under the firebox there is exit to the bench and the from it. And that's what makes it significantly higher. The space above the exit from the riser (the black oven) is elevated not only to avoid "plancha" (cookplate) banding but also so as the low space wouldn't become a narrow throat to the speeding gasses. My french is rather poor but I may get most of what Yasin is saying. BTW. Once I finish Trev's firebox (the second version) based cook range in our community headquarter I'll try to construct either lowered Batchblock at my allotment garden or Trev's III generation firebox (Aryan). Today's update: The thingy was painted with white clay opaint and the white oven reached a bit above 200 oC |

Bad News :-(
My friend has just let me know that the DSR firebox is not capable of heating the cook plate (cast iron 1x 0,6 m) and in order to boil up a kettle of water it takes approximately 1,5 hours. :-(
What can be wrong? I presented the film from Paul Wheaton place and the temp ranges the stove reaches.
How is that possible it does not work ?
Any ideas? I feeel pretty responsible as I advertized this firebox to him.

I thought that might be an issue when I saw what you had built. Paul Wheaton's is a DSR, the firebox exit port is directly underneath the cooktop. It's like a blowtorch of flame on the bottom of the hotplate.
In a DSR2 the heat has farther to travel before it gets to the hotplate, so more opportunity to diffuse into the gasses and masonry while in the afterburner. The hot gasses coming out of the DSR2 afterburner exit port are not going to be as hot as the jet of flame coming out of a DSR firebox port.

Isn't the issue the distance between the exit port and the cooktop? From the photo showing the stove without the cooktop it looks like the distance is something like 20cm.
