This is a waste oil burner that runs on WVO, WMO or any other type of used oil.
The Burner is simple in construction and the waste oil is burnt cleanly once the burner is up to temp. The benefit of Waste oil burners is of course free fuel.
My goal is to have an output of 200Kw which equates to burning 20L an hour of waste Vegetable oil.
The burner itself is a 4.5 Kg gas bottle with the top cut out. I inserted a 1- 3/4" pipe into the side which has a 90o bend inside the burner to maximize the swirl effect. this ensures the oil is burnt cleanly by allowing the burner to operate in an excess air condition.
The oil is fed in through the airtube and is blown in with the help of the 900W vac cleaner head I am using to supply the air. As I was able to max out the air supply in this test, I would like to find an industrial type blower with more output and would run a lot quieter.
In this test the fuel drum was approx 3 ft above the burner and with a 10mm hose was unable to keep up with the fuel demand until the drum had become quite hot. When i have the burner completed I will either use a small pump to pressurize the tank or use a fuel pump.
The burning chamber of the gas bottle is surrounded by a 205L drum with both ends cut out. the drum and burner are raised on bricks to get a drought around the burner and to slightly cool the outer drum. Given the drum still glows bright red, I will probably try to use a forced air supply to cool the space between the drum and the burner and lower the gas output temp.
For a heat exchanger i intend to use a large car radiator and pump the water through that with a large pump to prevent the water boiling inside the rad. I may also look at stacking one rad on top of another and run them in series or parallel to improve efficiency if the output temp is too high.
I intend to use the fans on the radiator to hopefully draw air in from the bottom of the drum and reduce the output temp of the gas going through the radiator.
I am looking at putting a plate over the top of the burner and direct the flames to an outer ring in order to keep the flames much shorter and away from the radiator core. I may also have to put another half drum on top of the other to give me enough height if this does not keep the flame low enough.
I am also thinking to use a 60L drum with the ends cut out around the burner to give me another layer between the burner and the outer drum to keep it cool enough to insulate and ensure all the heat goes up through the radiators.
This is self designed and built as I go learning from testing so I do NOT have plans. Those who are skilled to operate something like this safely will also be skilled enough to build their own from this description and Video and vice versa.
My pool is 75,000L capacity and I am hoping to be able to raise the temp of it by 30o C in 10-12 hours.

Drip Feed Veggie oil Heater Testby hatch789y1,241 views
@thierryanna
I feed the oil in through the air intake just after the blower. If the oil (WMO or Veg) get hot in the fuel supply pipe, it will char and eventually block the line. By feeding the oil in the air tube and having plenty extend into the burner, the oil is partially vapourised so it ignites as a gas, some goes in as vapor which lights readily and some still goes in as liquid.
Even though it gets hot in the air tube, it hasn't blocked so I surmise the residue is burnt or blown out.

my maths could be way out (most likely), but 200kwh only= 2.6J per sec per ltr in 75000ltrs??
