Intro to Oilburners Flashcards
In order for something to burn you need three things?
Oxygen,Fuel,Heat
Will oil burn as a liquid?
No must be vaporized.
How does a oil burner work?
A pump pumps oil at 100 PSI to a nozzle which atomizes oil. Then a electrode sparks for ignition and fan fan supply’s air for combustion.
What is a flame retention burner?
Flame is held close to the face of the combustion head.Flame is more compact.
What is a flame retention head?
Produces air swirl and combustion air recirculation flow which improves fuel air mixing.Profuces cleaner combustion 5-15% higher then old burners.
What are the components of an oil burner?
Pump, Motor, Fan,Fuel Unit,transformer or igniter,drawer assembly,housing.
What does a motor do on a burner?
Drives the fan and fuel pump at 3450 RPM in either two types of motors a ISIR or PSC.
What is a oil burner fan used for ?
Supplies combustion air for the flame. Must be kept free of dirt and are precision balanced.
What are the three basic parts of a pump?
Strainer- used to strain stuff before entering pump gears.
Pump:lifts oil from tank to regulating valve.
Regulating Valve: keeps proper pressure for atomizing oil.
What is the ignition transformer or ignitor used for on an oil burner?
Provides a step up from line voltage of 120V to either 10,000V or 20,000V.
What is the nozzle assembly?
Consists of oil feed pipe,nozzle,nozzle adapter,electrodes, retention head.
What three basic air directing elements does a flame retention head incorporate?
Centering opening for primary air, secondary opening slots,tertiary opening.
What is the primary air used for?
Where the oil from the nozzle is sprayed.
What is the purpose of the secondary air on a flame retention head?
Most important mixing of air and oil occurs.
What is the tertiary air slots in an flame retention head used for?
To blanket every bit of oil with air to complete clean combustion.
