Goodmorning everyone. I have been following you for some years from Italy, and a few years ago I built a mass stove with a Rocket burner, during a dedicated course. Now I would like to build something, or rather to adapt a DSR core inside a kitchen stove. Looking on the web, I think it is the most suitable because it is easier to adapt to size 4. I wanted to ask if possible to have measurements in cm or mm to be able to build it. for now thank you and look forward. Sorry for English, I use a translator to make it easier for me.

Hi Ugo, welcome to the boards.
It would help a lot if you could tell us which of the DSR cores you are talking about. There's the DSR1 of which develpment is stopped some years ago. And later the DSR2 development is done, having a short riser behind the firebox which works well. There are drawings of that one published although it isn't on the website as yet.
The DSR3 development is still not finished, this one sports a port in the firebox' ceiling and a ceramic tube in the top chamber. No drawings so far, just what I've got here in my workshop. In case this last one is what you want, I could measure what I have done so far and give you that.

Thanks, I'm happy to receive your reply. I was thinking of the DSR the first version. The one that has secondary air that passes inside a metal profile, and has a secondary combustion chamber with horizontal development. Everything is obliged by the size of my kitchen stove which is a lohberger 90. I am attaching a video for an idea of the stove. The modification I have thought involves a frame to raise the cooking plate, which I could make with a metal frame. in order to have the space where to insert the insulating refractory. I was thinking of the DSR version in the smallest 4 "size. I can't find the dimensions of the stove in question in cm. What do you think? m.youtube.com/watch?v=cpjKNAC1OzY&feature=youtu.be |

Thanks, and a real pleasure to hear your answers. I'll try with the measures of the post you sent me, size 3 ". I read that it has lengthened the combustion chamber to insert longer wood. I have 40 cm of depth available. Could I try to keep it long or would you not recommend it? convenient for not having to pick up the saw and review all the stacked wood. I ordered 600kg / m3 Vermiculite tiles in Germany to cover the combustion chamber and 1240c ° ceramic fiber. I'm waiting for it to arrive.

Good evening everyone. yesterday I managed to make a piece of stove. I had to follow the dimensions of the existing combustion chamber. I lined it internally with 1 cm vermiculite side walls and bottom. the base is with 3 cm refractory stone and under this 2.5 cm of vermiculite. the ceiling and with 2.5 cm vermiculite. above this or the afterburner, 1 cm vermiculite walls and ceiling, only one right side wall with 2.5 cm thick cutout. the photo is in the avatar, as I am unable to attach photos. the secondary air pipe is connected to the ash box and is 3 x 4cm, there is a slot for primary air 9cm x 2cm on the floor also connected to the ash box. in the ash box I have the possibility to regulate the air. the post combustor has a width of 15 cm and a height of 7 cm, and a door of 12cm x 4cm partly occupied by the tube. the combustion chamber width 18cm height 13cm. Surveys of the results will follow. I only have a temperature probe on the fumes outlet, the possibility of regulating the depression in the flue, and regulating the inlet air. this operations can be performed quickly. or change the geometry only by making it smaller.

The forums picture hosting is full, so you now have to upload your images somewhere else and link to them from here.

Good evening everyone. They write the latest updates. I tested the stove for 20 days with the construction measures described in the previous post. Not satisfied, I reduced the Door port to a width of 27mm. I've been testing for three days. the improvement and in the longer burning time. the temperature at the exit of the combustion chamber above the port is highest 780 ° centigrade, measured with the probe placed on the glass. the double vortex is formed. The power has decreased, it takes more time to bring the temperature of the flue gas duct on the stove outlet above 200 ° centigrade. The combustion at the beginning and end is a little dirty with soot.7:14 pm - 6 November 2021, loaded with small pieces of wood, 1/2 full chamber. Ignition on a hot stove, reached 835 ° C at the same point the other day. How many degrees will there be inside the flame temperature? youtu.be/nvLgcn3I1gAyoutu.be/f44ok1JuzfI |

Good evening everyone. I enclose a short video, to read the recorded temperatures. the stove is hot. I add wood to fill 1/2 chamber on the hot coals. the beginning of combustion dirties the glass completely, then the combustion cleans it. The temperatures with the probe inserted under the glass at the post combustor outlet will register a maximum of 1210 ° c and the fumes outlet 227 ° centigrade. youtu.be/jaCib96BqSs |
