Different Parts of a Waste Oil Furnace Different Parts of a Waste Oil Furnace

A furnace that takes care of heating, disposing, or burning used oil or waste oil is known as a waste oil furnace. It can generate free heat from motor oils as well as fluids that are petroleum based with the help of a waste oil furnace. Using a waste oil furnace is a good way to make sizable savings in the long run. Waste oil could be used by anyone ranging from those who own large fleets to individuals who have easy access to waste oil. However, the primary users of a waste oil furnace are companies that produce and accumulate waste oil and are able to utilize this waste oil as a heating system. Using economical heating is beneficial for places such as auto garages, car washes, and trucking companies. Here is a list of some of the different parts that go into making a waste oil furnace.

Pressure Nozzle

This is slightly different from a conventional nozzle. This nozzle can get easily clogged with the various impurities and deposits that are formed in the fuel. Therefore, a nozzle that uses an air atomizing siphon is used in the pressure nozzle. This nozzle uses air that is compressed in the atomization of fuel and functions very similar to an airbrush or a spray gun that is used to paint.

Preheater

There can be two types of preheaters: one that is built externally with oil being routed into an opening in the blast tube, and another that is an aluminum block accepting the nozzle of the siphon at one end. This aluminum block has air and fuel passages drilled into it. The cartridge heaters are accepted through the holes in the block. This preheater helps in preheating both the oil and air before it enters the chamber for combustion.

Air Compressor

Supplies air mainly around the fringe of the nozzle. This helps the oil get atomized. There is also an adjustable regulator through which the air supply is routed. There is a solenoid valve that turns the air flow on and off.

Float-controlled Valve and a Small Tank

This ensures that there is supply of fuel with constant pressure. This guarantees that a constant height is maintained as far as the fuel is concerned. The level of fuel will either be above the nozzle or below the nozzle. This mainly depends on kind of flow rate that you want to achieve. There is also a solenoid valve in some furnaces where the fuel level lies above the nozzle. This ensures that the fuel will not flow when the burner is switched off.

Temperature Controller

This is usually a PID controller that is digital in nature and comes with an alarm output. This ensures that the preheater is at the right temperature prior to the burner attempting to start.

Turbine Retention Head

The turbine retention head helps in taking care of the waste oil that is generally longer than your standard pressure nozzle flame.

Electrodes

A high-voltage arc is provided continuously from electrode to electrode. This helps in the waste oil being ignited as it gets sprayed out of the nozzle.
