What does a interrupted ignition primary control mean. - Answer It interrupts the ignition transformer ____________________ employs an electrode spark for a brief period at the beginning of the burners run cycle. Once a flame is established, the spark stops. - Answer Interrupted ignition A permanent split capacitor (PSC) motor that is running and up to speed will have the start winding ____. - Answer Energized A permanent split-capacitor motor has a ____. - Answer run capaci...

Ch 1 High Pressure Atomizing - Answer 100+ PSI fuel pump forces oil through a nozel to break (atomize) the oil into small droplets thst are vaporized abd burned in suspension in the combustion area. Electrodes close to the nozzle supplies heat for ignition and a fan supplies the air needed for combustion. Ch 1 Flame Retention Burner - Answer An oil burner, designed to hold the flame near the nozzle surface. Strongly swirling air pattern recirculates combustion products for more complete...

The key final adjustments for most oil burners is - Answer Combustion air The High static air pressure created by today's oil burners - Answer Enable boiler and furnaces to have tighter more efficient, heat exchanger passages Dirt or lint build-up in the bevel of the burner fan blades will? - Answer Reduce the amount of combustion air How do high pressure atomizing oil burners, light oil on fire? - Answer They pressurize the oil to turn it from a liquid to droplets mix th...

The key final adjustment for most oil burners is? - Answer Combustion Air Dirt or lint build-up in the bevel of the burner fan blades will? - Answer Reduce the blade bevel and reduce the amount of air delivered To change the air ratio for different firing rates with an adjustable head burner you? - Answer Move the head forward or backward, against or away from the ring closing or opening the tertiary slot One advantage of high static pressure burners is? - Answer Allows manu...

How many BTU's does one gallon of #2 fuel contain? - Answer 139,000 when the viscosity of the fuel entering the nozzle increases _____________ increases? - Answer the flow rate also increases. Flash point is? - Answer The maximum temp a fuel can be safely stored & handled without serious fire hazard. Fire point is? - Answer Ignition point is the lowest temperature at which fuel vapor will initiate and sustain combustion. Pour point is? - Answer the lowest temperatur...

The final adjustment for most oil burners is? - Answer Combustion air Dirt or lint build-up in the bevel of the fan blades will: - Answer Reduce the amount of combustion air. To change the air ratio for different firing rates with an adjustable head burner you: - Answer Adjust the position of the draw assembly in the air tube. One advantage of a high pressure burner is: - Answer They enable boiler manufacturers to design tighter more efficient heat exchangers. One gallon ...

what are the 3 basic parts of combustion? - Answer fuel, heat, air high pressure oil forced through a nozzle does what? - Answer atomizes the oil, mixes the droplets with air, allows oil to burn modern flame retention head burner motors operate at what speed - Answer 3450 rpm dirt or lint buildup in the bevel of the burner motor fan blades will cause what? - Answer reduce the amount of combustion air what are the two types of burner motors? - Answer split phase and per...

Flash point - Answer The flashpoint of a fuel is the maximum temperature at which it can be safely stored and handled without fire hazard. The flashpoint of a blended fuel is that of the fuel in the blend with the lowest flashpoint. Ex. Number two fuel has a flashpoint of 100 minimum. Fire Point - Answer The fire point is the lowest temperature where the vapor of a liquid will initiate and sustain a combustion reaction Ex. number two fuel fire point is approximately 500°F P...

High pressure oil burner - Answer Any oil burner that operates with a punp pressure of 100psi or greater. What Components make up a high speed oil burner? - Answer A) Burner Chassis B) Blast Tube (With nozzle assembly) C) Burner Motor D) Oil Pump E) Blower Wheel F) Motor/ Pump Coupling G) Ignition Transformer/ Igniter H) Air Bands I) Diffuser/ Retention Head 3 types of domestic oil burners - Answer 1. Power burners (Atomizing) A. High Speed- operates at 3450 RPMs ...
