Preamble

I worked at the garage faced with the problem of disposal of wate oil. Recently I found in the Internet an interesting scheme, and decided to build diy waste oil heater, or Babington burner, because this burner works with oil with any pollution level
The basic idea: the oil flows onto the spherical surface and spread by thin film on it. If supply air or gas through a small hole in the surface (just below the layer of oil), the oil will be sprayed. If you set fire - you get great oil torch.

Materials

• Bucket
  
• Sheet metals
  
• Oil pump with speed control
  
• M10 bolt
  
• Copper tube
  
• Sensors of heat and light
  
• Solenoid air valve

Tools

• Drill
  
• Grinder or hacksaw
  
• Welding machine
  
• Wrenches, pliers
  
• Soldering

DIY waste oil heater



• Original scheme of Babington burner

  
  

  


• How it works

  
  Waste oil flows onto the nozzle, so burner would work with waste oil any pollution level. Compressed air consumption is very little, only a few liters per hour!
  

  You can use a handmade compressors of refrigerators or compressors from aquarium

  
  Also, the waste oil flowing down from the ball should be bring back into the tank, which means that the oil pump is need.


• Step 1

  
  I placed сar oil pump to a sheet of metal with motor and gear and an electronic speed control to be able to regulate the supply of oil. My diy waste oil heater will be placed on the bucket filled with waste oil.
  

  



The nozzle



• Step 2

  
  I can't fount metal ball, so I welded a piece of stainless steel to the M10 bolt and make it spherical.


• Step 3

  
  Then drill a hole in the center of the screw with diameter of 5 mm. Press a piece of aluminum into it, and in aluminium I drilled a hole with 0.3 mm diamete.
  

  It's recommended to 0.25mm hole

  
  

  

  
  

  


• Step 4

  
  The nozzle inserted into a cast-iron tee 1.5 ", produced to a tee base with hydraulic lock for security.
  

  


• Scheme

  
  Here is a scheme of my Babington burner
  

  


• Step 5

  
  Make a spiral of copper tube


• Step 6

  
  Attach it to tee
  Assembled homemade waste oil burner. Oil is flown through the copper pipe. The tube is bent into a spiral, to provide heating oil
  

  Hot oil becoming more liquid and better atomized

  
  

  


• Nozzle

  
  Here you can see a nozzle
  

  

  
  It is working! Nozzle works perefectly, oil is atomizing very good
  

  



Automation of Babington burner



• Step 7

  
  Then I thought about complete automation of my waste oil heater. I want to make the boiler with waste oil for heating. So I got a pair of solenoid air valves.
  

  


• Plan

  
  There is an idea to use a propane torch to ignite Babington burner, with the ignition coil from the car. You can also use propane instead of air, then ignition burner is does not need for homemade waste oil burner.
  How it would work: the control unit opens the valve of the gas, submits a spark. As soon as the thermocouple voltage occur, the control unit switches off the ignition and after a short time includes supplying oil and air, after which the flame on the burner is controlled by an optical sensor. As soon as the stable flickering flame, the gas supply to the burner will start to overlap. There will also be a temperature sensor, and after overheating Babington burner will be shut down, cool down and turn on again.
  Today I replaced nozzle with twice little one, and Babington burner start burn weaker (it's good, because erailer it was too hot to stand by). Also you can drill two nozzles nearby, and separately control each one, so you achieve step by step power control


• Step 8

  
  Startup burner for Babington is chinese torch with piezo firestarter
  

  

  
  

  

  
  

  


• Step 9

  
  Diy waste oil heater is supplying by propane with pressure of 0.2-1 kg / cm. Weld a pipe with a candle for the automotive mount and the starting burner tube under an optical flame sensor.
  

  

  
  

  


• How it works now

  
  Starts great, with the first spark is lit steadily, the flame is blown. Propane flows with low pressure so that the burner can operate in cold weather, when the pressure in the tank drops to 0.5-1 kg / cm2.


• Step 10

  
  Also i found thermocouple
  

  


• Step 11

  
  Got an infrared phototransistor for optical sensor
  

  


• Step 12

  
  Developed a simple circuit. LM339n chip is taken from the computer power supply
  

  


• Step 13

  
  All assempled
  

  


• Sensor's demonstration video

  
  


• Step 14

  
  More. Steal plates for heat resistant for Babington burner.

Results and tips

• Airflow is very small, only a few liters per hour.
  
• Babington waste oil burner works with oil of any pollution rate (metal chips or anything)
  
• Oil consumption is also very small
  
• Warms much more than you can imagine
  
• Solves the problem of disposal of waste oil
  
• With the right approach to automation can obtain "smart house" with autoregulation of temperature
  
• Absolutely no smoke and very hot: the power of not less than 10 kW.
  
• The air pressure at the nozzle 2 kg / sm²., if less - is not burn, if more - the flame breaks.
