No torch, we use a little lighter fluid and oil mixed and it gets moving pretty easy.

Heres where it gets tricky. Yes and no, the Ozzirt design is more efficient around 300-500 degrees but that is really it. Above that the oil seems to vaporize too quickly and burn too short to fully burn and thats with either design. I am going to modify our heater at some point and properly seal the bottom chamber and add more air holes to the secondary burn chamber. You need a hot lower chamber with little oxygen, and as much oxygen as you can get in the second chamber and if your design works out well I would say 600+ degrees should be no problem and produce very little soot.
My heater uses a 50 gallon water heater as the main body/heat exchanger, a piece of 10" cast iron plumbing pipe as a secondary burner and a cheap dutch oven as a primary. The exhaust is 8" stove pipe from Lowes and there is a lot of it in the shop (12 foot ceiling) so there is a lot of area for heat exchange.
Here is a pic of the heater please pardon the mess around it, its as bad as it looks lol

Hey everyone! I have a shop in the Tri Cities area and it stays pretty darn cold in the winter. Its an 80x60 cinder block building that is poorly insulated. We ran a MEN type heater back in 2010, then converted it to an Ozzirt style last year. The Ozzirt design is probably the best a drip feed can get. The two stage setup burns nice and clean until my friend wants more heat and cranks up the feed lol. It will burn with a light grey smoke and zero soot at around 450 degrees and can ramp up to 600 on a good batch of oil mixed with diesel. We have a few problems with the lower chamber not sealing well as well as oil pooling occasionally causing it to "run away" to 800 degrees or so and smoke the place up a bit. We work on cars so exhaust doesn't bother us, but we do have to air the place out which sucks on a 20 degree night.
When the oil burner and wood stove are running good it stays in the high 60 with the outside temp as low as 15!

We converted from this style to an Ozzirt style for this reason. Your mixture is running rich, try running at a much lower drip rate so you can get a longer (more complete) burn. Even though the heater is running hot it is probably wasting a third of the fuel that you are trying to burn. A slower burn will generate a decent amount of heat and much, much less soot. The only time you should have any soot generation is when it is cold
