Massachusetts Oil burner Practice
Questions and Answers Graded A+
1 gallon of #2 oil contains approximately how many BTU's? - ANSWER-140,000 BTU's
A cause of pulsating oil pump pressure and a pulsating fire is - ANSWER-Air leaks in
the suction line
A fuel de-aerator: - ANSWER-Eliminates the need for a return line back to the tank
A proper combustion chamber: - ANSWER-Is large enough so the fire doesn't touch
(impinge on) any surface, reflects heat back into the fire, and is made of material (like
ceramic) that heats up quickly and cools off quickly
Airstats are found on what type of heating systems? - ANSWER-Forced warm air
systems
All petroleum products are chemical compounds of - ANSWER-Hydrogen and carbon
An advantage of flame retention burner is - ANSWER-Their high static pressure enables
boilers and furnaces with tighter more efficient heat exchange passages
Aquastats are normally found on what type of heating systems? - ANSWER-Hydronic
Combustion performance testing can indicate: - ANSWER-Improper air oil mixture, too
much combustion air, and low pump pressure.
Delayed ignition can be caused by: - ANSWER-Weak ignition transformer
Delayed opening oil valves are used to? - ANSWER-Allow oil pump to come up to
speed
Dirt or lint buildup in the bevel of the burner fan blades will - ANSWER-Reduce the
amount of combustion air
Flashpoint of a fuel is an indication of - ANSWER-The lowest temperature at which the
fuel will flash but not continue to burn
Fuel units (oil pumps) preform the following functions - ANSWER-Move oil from the tank
to the burner and deliver oil at a constant regulated pressure to the nozzle
How can a damaged heat exchanger be detected on a forced warm air system? -
ANSWER-With a smoke trace candle
