Two types of oil burners pumps | single and dual stage |
Three functions of the oil burner nozzle | 1) Atomizing 2) Metering 3) patterning |
3 storage tank design | indoor, outdoor, and underground |
which is storage tank design? | indoor, easy access to test. |
how do you test water fuel tank? | wax on the stick |
Bypass plug product remove | one stage |
Fuel line not required | PVC or cast iron fittings |
Process of fuel combustion | atomization |
one pound fuel oil | 3 |
One gallon fuel produce how many btu | 140,000 btu |
How much excess air? | 50% |
Fuel oil pump rotary pump? | false, gear driven design. |
First stage | pull from tank for long distance. |
Second Stage | push to nozzle into burner |
List six of the main components of a fuel oil burner | 1)End Cone 2) Air tube 3) fuel pump 4) Blowing housing 5) Blower wheel 6) Nozzle |
how does end cone on retention burner better combustion ? | Squirrel, increase volume |
Three type of combustion heat, water, and vapor | False |
Most burner motors are | PSC |
burner motor connect to fuel pump | flexible coupling |
The burner fan is | squirrel cage |
Three functions of nozzle | 1) atomize 2) metering 3)patterning |
Two information stamp of nozzle | 1) orifice size 2) spray angle |
Why spray pattern is important? | Design of the burner box |
Spray angle | 30 to 90 degree |
Nozzle can be use as file by metal brush. | false, replace it. |
Name the three spray patterns | 1) Hollow 2) semi-Hollow 3) solid |

Fuel oil compose of | 1) hydrogen 2) carbon |
If the oil tank is located above the oil burner | One-pipe system |
Oil storage tank is located below the oil burner | Two-pipe system |
Oil lines should be: | 3/8" OD copper lines, made of copper, steel, or brass. Never use PVC nor Cast-iron, flare connection |
Oil deaerator | Oil pipe component that allows a one-pipe system to function as a two-pipe system |
Ash content definition: | The amount of combustible materials contained in the fuel oil |
Distillation quality definition: | The ability of the oil to be vaporized. |
Pour Point definition: | The lowest temperature at which the fuel can be stored |
Carbon Residue definition: | The amount of carbon left in a sample of oil after it is changed from a liquid to a vapor by being boiled in an oxygen-free |
Viscosity definition: | The thickness of the oil under normal temperature |
Ignition Point definition: | A few degree higher than the flash point |
Flash Point definition: | The lowest temperature at which vapors in the air above the fuel oil ignite for a short period of time when exposed to flame |
