i do not see much discussion on batch rocket stoves/mass heaters.
i am interested in an application that can be used for doemestic/cooking/water heating/mass heating. also for semi commercial use. heating a greenhouse through possibly hot water radiators.
not much info about batch rockets. yet some of the prinicples possibly do get carried over from basic rocket mass heater design principles. apparently there is a given distance between the top of the riser and the underneath of the bell. which i understand should be betwwen 2" and, 3". then there is the distance between the outside of the riser and the inside of the bell. this could be something to do with temperature differentiation; if this is the case then horatios could be given for say. different ideal temperatures within the riser at different points that would compare to the outside the riser at different points. a clean burn denotes complete combustion. i originally had thought that a rocket burns unimpeded until it burns out with the rocket roaring. this is the simple and maybe best approach. yet most rockets that i have seen have feed size chutes that have to be constantly fed. this might be ok for the size of the rocket/j tube. yet alot of these designs with small feed chutes do not even have bell covers, and in this respect are used for mobile applications, then the same size of design if fitted with a bell, then becomes a static installation. in this respect the size of the feed chute means that the fire has to be constantly tended to. then comes the batch rocket obviosly only suitable for static installations.
with the batch box could mean that different principles apply. controlling air flow could mean everthing yet with this the rocket could be replaced by the name of a clean burn stove. a complete burn in a controlled space is probably the main aim for everyone that is interested in a ststic application.
Hello Mervyn, Welcome to the forums.
One great place to start to get to know about Batch Rockets is here: Batch Rocket website You can also search Permies.com for many conversations on them or also at Proboards Good luck
