hi there im new to this but am looking at building a rocket stove . maybe 2
i live in smokeless area in the uk and have once had a complaint from runing a wood burning stove in my garage [ external flue ] . from a lot of vidio clips i have seen online people claim that the simple box steel design in a k shape creates no smoke. that would be great for me . but im a little confused as there are outher desighns that use the heat from the burn in various ways to either pre heat the in coming air. or funnelthe flue gasses to get the most out of them resulting in a cooler outer flu. its a bit confusing to be honest. and also i have acess to a lot of thick steel pipework and gas cylinders. and there are meany people making designs. and i also read about the temp being hot enough to burn the steel. so it seems a bad idea to build this. right ?
also i am half way throw building a hot tub. with about 1000L capacity, would like to make a smaller basic k design one with a jacket around the flue , pump assisted to get the hot water flowing quickly throw, as i have seen a fer designs relying on thermal cycling to much and the unit ends up kettleing .
i was thinking of making this smaller unit out of out of some medium size copper tube, the flue being about 67mm with a outer jacket being 76mm filled with water
my thinking of using copper is that if i dont insulate it to much i dont thing it will reach the temp to melt the braising, the heat transfer of copper is better then steel. and a steel heat exchanger will result in rusty water in the hot tub
any advise would be great . mainly i want a smokeless burn .
the using copper idea might be great . but that fact mo one has done it yet means i think im missing some major isue.
