built my first batch box rocket today. very basic. i adapted the formula to the size of my bricks so i could get the port dimensions right, then made everything else to fit. it was a real quick and dirty build but worked well. all the bricks where wet as i am working outside so wasnt expecting much. i was pleasantly suprised how well it worked. i used the riser from the j tube experiments. a 150mm piece of SS flexi pipe inside 2 20 ltr oil drums filled with perlite. the formula came up with 138mm for the riser diameter so a bit over. i didn't have anything to make the v with so the wood was just sitting on the floor. no insulation and quite a few air gaps so as i say very quick and dirty.
spent last night reading the thread on the development of the design so had some idea of what i was doing. i doubt i will use a rocket for heating the yurt as i am very resticted on height but may try and make one for cooking. will use the aquaboard i have to make an improved version. i dont have a p channel yet. i have a question about the shape of the p channel. could i use a tube with the correct CSA and flatten the end to the correct size?. thinking iron plumbing fitting using a nipple and a 90 degree elbow. i filled the stove with a mixture of dry blackthorn and oak. at the top of the burn i was getting the rams horn flame. the primary air slot was around 90 x45 mm and the p channel was 50 x 15mm it was more a gap in the bricks rather than a channel,but was i think in the right place right above the port.
for the yurt i am working on a rocket/spike design running on biodiesel. will start another thread for that one though.
