The dimensions are tuned for max performance .If you want faster heat up times and the ability to burn any fuel.This burner nozzle is made for blacksmiths and scrappers looking to forge and smelt .
Melt entire engine blocks in minutes This device is also great for kilns.
It uses compressed air to operate and burns any liquid fuel . This is a siphon nozzle and does not require a pump to operate .
Cranks out up to 1.9 million btu or over 570 Kw consuming about 50 LPH at that rate . For waste oil to achieve this power you need a oil pump or you must raise the fuel tank at least 6' ft above the height of the burner
This device can run a propane tank at full blast at over 2 million btu
This device needs a combustion chamber .
I also sell smaller nozzles
Heavy metal in waste oil are dangerous , if you use waste oil it must be outdoors or in controlled ventilation conditions
Be safe and Good luck friends
