LOW PSI OIL BURNER OPERATOR P99
EXAM WITH CORRECT ACTUAL
QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS LATEST ALREADY
GRADED A+
1. What is the primary function of an oil burner?
Answer: To atomize fuel oil for efficient combustion.
Explanation: The oil burner breaks fuel oil into fine droplets
so it mixes properly with air, allowing complete combustion
and efficient heat production.
2. What is the most common fuel used in low-pressure oil
burners?
Answer: No. 2 fuel oil.
Explanation: No. 2 fuel oil is widely used because it is easy
to atomize, burns cleanly, and is suitable for residential and
light commercial boilers.
,3. What is the purpose of the combustion chamber?
Answer: To provide space for fuel-air combustion.
Explanation: It is where the fuel and air mixture ignites and
burns to produce heat energy.
4. What does a cad cell do in an oil burner system?
Answer: Detects flame presence.
Explanation: A cadmium sulfide cell senses light from the
flame and signals the control system that combustion is
occurring.
5. What happens if the cad cell fails during operation?
Answer: The burner shuts down.
Explanation: Without flame detection, the system assumes
a failure and stops fuel flow for safety.
6. What is atomization?
, Answer: Breaking oil into fine mist droplets.
Explanation: This increases surface area, allowing better
mixing with air and efficient burning.
7. What is the function of the fuel pump?
Answer: To deliver oil under pressure to the nozzle.
Explanation: It ensures fuel reaches the burner at the
correct pressure for proper atomization.
8. What is the standard oil pressure for most low-pressure
burners?
Answer: 100–150 PSI.
Explanation: This range ensures proper atomization through
the nozzle.
9. What is the purpose of the ignition transformer?
Answer: To generate high voltage for ignition.
Explanation: It produces a spark to ignite the oil-air mixture.
