| Question | Answer |
|---|---|
| What are three products of combustion? | 1) Heat 2)Water Vapor 3) Co2 |
| 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 |
| Which type spray burner use larger burner? | Solid |
| Air blowing combustion chamber burner through | Air tube |
| Metal rode insulate ceramic insulate would identify | electrode |
| What determine the shape combustion chamber? | Nozzle spray angle |
| Four Primary control functions: | 1) Safety function 2) shutdown burner 3) ignition process 4) Start and stop blow motor |
| What are two types of primary control? | 1) Stack switch 2) cad cell switch |
| Primary control that use hot and cold contact | stack switch |
| Cad cell be able shutdown burner if flame is not present | False |
| The typical resistant cad cell sense light | 600 to 1000 ohms |
| STI-P3 stands for | Steel Tank Institute-Protected 3 ways |
| What are four characteristics of forced-air furnace? | 1) low-boy 2)upflow 3)downflow 4)horizontal |
| 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 |
