waste oil burner "ozzirt" type. Works well
veggie:
Interesting design !
The secondary burn chamber should add some great efficiencies and heat capture.
I assume the burn pot is removable for ash cleaning?

Okey-dokey
I realise this isn't a subject in which there's a lot of interest - so my apologies to anyone who feels his time is wasted by it. But it's only really my time wasted
There are lots of simple draft-type burners around and they're capable of immense heat, limited only by one's personal courage, as far as I can see
I must have watched 50 or 100 YouTube vids of burners ranging from awful to unbelievably efficient-but-complex. So a while back I posted some pics and a short video or two of my iteration of an "Ozzirt" type drip-feed burner - it was just proof-of-concept, really, but I was encouraged by the fact it would respond to "tuning" the air intake at bottom, midpoint and top (primary, secondary & tertiary burns - if you like) and the fact that was repeatable. Plus it was easy to have it burn "clean" - at least in terms of exhaust output
So I'm 2/3 of the way of building Mk11 as mentioned a couple of weeks ago. See pics attached?
It's still rough, still proof-of-concept. I wanted to see if the Ozzirt drip-feed design would burn through a big chamber and around a baffle - to capture and dissipate a chunk of the heat - and also if it would do that with a "cook-top" top section which, in an ideal world, would incorporate sections that were "hot", "bloody hot" and "simmer"
So here's some ugly cut-and-shut construction. It's a hunk of 300mm (12-inch nominal bore) pipe with a 12mm (1/2 inch) wall - should accumulate a bit of heat with a bit of luck) and the top is made out of some scraps of 12mm flat too
There's a base (not shown cos I forgot) which incorporates a stand etc . . ,
The intake/burner bowl/burner tube is a re-use of the one in the previous post - but I welded a section of 100mm BSPT male thread onto it and welded a 100mm BSP socket onto the bottom of the intake part of the big "stove" chamber - so the burner tube and air intakes assembly hangs off the elbow shown and is removable to play with as long as the thread lasts (not long I suspect)
At the exhaust end of the stove chamber thingie there's a 125mm flange welded in place two-hole-square, so I can attach whatever I like to it, flue-wise, simply by building it on the end of a suitable flange with two-holes-square orientation
Like any piece of amateur cut-and-shut, it's ugly - although it'll clean up with some weld-grinding. Basically I tacked stuff together, heated it with the gas to bash into shape in the join areas and filled the gaps with weld, It'll work well-enough to prove/disprove the concept
My aim is to have a "stove-type" burner which is safe-enough to put in my shed and which will radiate a chunk of heat and which has a "cook top" function. So this is a first step towards that. I wouldn't anticipate building anything that one would leave burning unattended
The base (not shown cos I forgot to photograph) incorporates a steel "tank" for want of a better word, made from 8mm plate, and with 40mm BSP sockets at each side - because I'd like to see if there's a safe way to "pre-heat" the heavy oil of which i have several tonnes available
So there we are. Excuse long-windedness
