Mk3 burner prototype running clean and pretty well
BruceM:
Thanks, MikeN. Not dong well but life goes on.
Good luck with your MK4 burner!

I built several back before there was internet and that information, none of them came close to what you have achieved.

Fwiw I reckon they are effectively just a wide-open chimney/draft with a burner stuck on the bottom; and getting the burner to run OK is maybe about air flow & a way to instantly turn a drip of oil to flammable vapour? Because Mk3, with that 4” stainless steel bend, once that stainless started to glow red it just roared & ran away like an old diesel burning its sump oil - scary & not good inside a building
I’m not blind to their shortcomings though. It’s like cooking sausages in a pan - you have to be there and be ready to tweak & tinker or you’ll have them charred on the outside & pink in the middle. The best analogy might be a petrol engine with a wide-open throttle & no carb & trying to keep it running by dripping gas into the intake tract lol

Troubles I had with my various efforts were fuel control. They all suffered same fault and ultimately failure. I would prime burner with K1,, and turn on the waste oil. As things warmed up the oil drip would increase, Id turn it down and then as things cool that would then also slow the flow. Thus to keep them going required constant fiddling with the fuel valve. This was all an attempt to heat my workshop on the cheap. I finally gave in and purchased a Lannair waste oil burner that was modified by a Mennonite that realy knows his stuff. His modifications are many but the primary one is a positive displacement pump that gives same delivery to burner and also a thermostatically controlled heater after the pump just in front the orifice. Everything is controlled via wall in thermostat. In 4 years and close to 3000 gallons of waste motor oil I have done nothing to it other than remove ash 2-3 times over the winter. It uses some electricity to power it and also needs air provided by my shop compressor but usage is minimal.
I do keep on watching you smart people and your DIY projects as I have an almost endless supply of oil and a couple places to use it for heat IF I could do it on the cheap.

Yep. Dead right on both counts - fuel control & temp change. They are certainly the two bugbears. I will just keep tinkering & see if I can minimise the downsides of these enough that it’s not a biggie. We’ll see I guess. Appreciate the input. Cheers
