Waste Oil Burners

Waste Motor Oil in Burners
Waste Oil Burners are heaters that run on oil. Most are originally designed to run on the less viscous “fuel oil” and are modified to run on WMO. Waste oil burners are often found in shops or commercial facilities. Common mods are special nozzles and pre-heating the waste oil prior burning. The WMO should burn without any smell or smoke. A typical gallon of waste oil contains 140,000 to 165,000 BTU. The most popular burners are Beckett AF or a Carlin gun-style oil burner. A conversion of a burner costs 300-1000. There are two types of nozzle conversions: Pressure Nozzle - need really clean oil and are easier to convert(5 micron min.) Siphon Nozzle - require compressed air, but clog less frequently than Pressure Nozzles(50 micron min.) The other main mod is the preheating. The viscous WMO needs to be heated to at least 200 *F.

Drip-Fed waste oil Burner
These are far less complicated than the injection style burners. Waste oil simply drips from a copper tube on a hot steel plate which causes the oil to vaporize and be burnt by a flame. These are very cost effective, yet need to be supervised like a campfire. There are some great examples on Youtube.
