High-Yield Review Guide
1. Describe the primary cause of glazing in oil burners and its impact on burner
performance.
Glazing is a result of using low-quality fuel, which leads to higher
emissions.
Glazing is caused by excessive fuel flow, resulting in increased soot
production.
Glazing happens when the burner is operated at too high a
temperature, causing metal fatigue.
Glazing occurs due to incomplete combustion, leading to the
formation of a glass-like residue that can hinder burner efficiency.
2. What is one potential consequence of oil spray contacting the walls of a
combustion chamber?
Enhanced fuel economy
Improved air quality
Incomplete combustion
Increased energy efficiency
3. If a building's fuel-oil piping system is installed without proper accessibility
for maintenance, what potential issues could arise?
Improved efficiency of fuel transfer
Enhanced aesthetic appeal of the installation
Reduced need for inspections
Increased risk of safety hazards and compliance violations
,4. If the Main Fuel valve fails to close during an oil burner operation, what
potential issue could arise?
Increased efficiency of the burner operation.
Excess fuel flow leading to unsafe combustion conditions.
Improved safety measures in the fuel system.
Insufficient fuel supply causing the burner to shut down.
5. Describe the significance of a level gauge in maintaining safety within fuel oil
storage systems.
A level gauge is primarily for aesthetic purposes in fuel oil storage.
A level gauge is crucial for monitoring fuel levels, preventing
overflows, and ensuring safe operation of the fuel oil system.
A level gauge is used to measure the pressure within the storage tank.
A level gauge helps in determining the viscosity of the fuel oil.
6. Could occur if an oil burner is allowed to be fired into the appliance's oil-
flooded combustion chamber:
soot entering the house
an uncontrolled fire may damage the appliance
all choices
an explosion
7. A common procedure used to prepare oil for combustion is called ___ _.
liquidation
atomization
, aeration
optimization
8. If a building's oil burner is found to be operating improperly, what steps
should be taken to rectify the situation according to the guidelines?
Increase the fuel supply to improve performance.
Ignore the issue until the next inspection.
Replace the oil burner without inspection.
Conduct maintenance and ensure compliance with safety protocols.
9. Describe the consequences of the Primary Relay Control failing to detect a
flame in an oil burner system.
The fuel will overflow into the storage tank.
The system will shut down to prevent unsafe conditions.
The flame will become larger and more intense.
The oil burner will continue to operate normally.
10. What is the primary function of the oil storage tank in a fuel-oil system?
To regulate the temperature of the fuel oil.
To provide backup fuel supply during emergencies.
To filter impurities from the fuel oil.
To store fuel oil for the heating system.
11. What is the primary purpose of insulated firebrick in an oil burner's
combustion chamber?
To retain heat and improve combustion efficiency.
, To reduce noise during operation.
To filter impurities from the fuel.
To prevent oil leaks.
12. During a routine check, Amanda spots a leak from the bearing connected to
a pump. Amanda checks the oil flow rate and finds them to be normal. What
could be the cause for the bearing leak?
Broken oil rings
Poor bearing material
Use of improper lubricant
Damaged seals
13. What is the primary function of the Gauge Glass in a steam boiler?
To provide a visual indication of the water level.
To measure the temperature of the steam.
To regulate fuel flow to the burner.
To control the pressure within the boiler.
14. Describe the importance of the suction pump in maintaining the efficiency of
a fuel-oil system.
The suction pump is used to mix fuel with air for better combustion.
The suction pump prevents oil from leaking into the environment.
The suction pump helps in cooling the oil before it reaches the
burner.
The suction pump is crucial for ensuring a continuous flow of oil to
the burner, which is necessary for efficient combustion.
