BBR as an abbreviation of Batch Box Rocket, so DSR for Double Shoebox Rocket. The last one is like a pet name, sounds cuddly... I like that, thank you.

... I thought to google 'DSR' as it seemed to ring a bell... some of the 'disambiguations' that Wikipedia came up with are: Doubly special relativity, a proposed modification of Einstein's special relativity theory; Design science research, a set of analytical techniques and perspectives for performing IS research; Demand-side response... *phew* Luckily no STDs.

I didn't list them all so here are the ones in the direction of the STDs: Dansk Sygeplejeråd, The Danish Nurses' Organization Donor Sibling Registry, a US organization serving donors Designed sanitary relief, a civil engineering structure designed to relieve wet weather flows from municipal sanitary systems

In the Allerton setup it would be interesting to put an oven just after the exit on the back, towards the back not down, which in turn puts the gas in a bell. I think that if you keep the original design until the rear exit the combustion is not affected, but this has to be said by Peter

DSR yes!
Desire has much the same meaning in English
Thanks always Peter for your tireless research and willingness to share your discoveries

peter the non-symmetry of the throat position in the core is due to a practical or technical factor?

Peter, could the port be moved forward to the front?

Not quite, the exhaust would be rather in the side of the oven instead. The port in the middle, and the oven wouldn't be a dome. I'd try to mimic the original double shoebox as close as possible. more like this then Well, re looking at this drawing. The simplest solution i see. Keep the original shoebox, as is originally. And move the oven in this pic, to it's side. Bit like the cooktop side channels on the cooking stove earlier in this thread. If the shoebox is made out of insulating firebricks. No heat, or barelly any should be lost.

It is done for a practical reason so the top box could be placed a bit to the right, creating a bit more space to the left. The port is still dead centered in the top box because I think the exact position in the firebox isn't that important. The result being a small cook stove consisting of uncut bricks for the most of it. I did the design in one day at the premises so there were some inevitable small bloopers to resolve during the build.

Peter, could the port be moved forward to the front? No MAx, I don't think so. It took some weeks of fiddling and tinkering during August and September to confine the fire fountain to the back of the tunnel, away from the exhaust opening.

The drawing is not correct but the idea is clear, the oven could be next to the core. Instead of a single switchback the size of the tunnel, it could be much larger so it would be able to house a pizza. Nice idea my friend, no doubt there will be more solutions like this. The absence of the vertical riser opens up a multitude of possibilities.

On the subject of ovens I quote myself from last night in another thread. Hello Antti, I had a thought drop in last night relating to the oven you have... I have been checking my chimney temps more during my burns the last few days and found that they go down rapidly at the end of the flaming part of the burn. I assume that the chimney still draws a similar volume of air through the fire box and oven at this point, compared with the height of the flames and also during the coaling phase. So if my assumption is right it seems that a lot of cooler air is pulled through the oven during the coaling phase which is transferring heat originally captured in the oven and move it into the bell. ... so if there was a by-pass/valve that could let the gasses go through the oven until the end of the flames, and then direct the gasses straight into the bell while the coals are burning out, the oven temps should stay up. Does this make sense? I have not tried it and am not sure how it would be possible to make it. A metal flap would die quite quickly at the end of the heat riser. A brick/split would be tricky to operate from the outside. So my thoughts go to a piece of ceramic glass, but again how to make the design to operate it? Or is this just an issue for me because of the wood I burn and having 4cm thick heavy fire bricks in the fire box? Your thought will be welcome.
