This burner is easy to build with off the shelf and easily found parts. It works similar to a babbington type but is a simpler design still.
While many pressurized burners use expensive Delevan siphon type nozzles, this Spray burner can be made using regular fittings and can deliver a wide range of outputs.

It requires only one valve for the fuel flow and can run on a variety of fuels from waste oil to diesel, kerosene or turps. It is shown running on and lighting up on straight used veg oil with no additives. The tank is pressurized to 1520 PSI but can be higher or lower according to the heat output required.
