Oil Heat Exam Actual Questions with verified
correct detailed Answers Graded A+ Latest
Update 2025
What is carbon residue? --- correct answer ---the amount of of carbon
left in a sample of oil after it is changed from a liquid to a vapor by
being boiled in an oxygen-free atmosphere.
What residue will there be if oil burned properly? --- correct answer -
--None
How much water/sediment should be left in oil after refining? ---
correct answer ---Lowest amount possible.
How does sediment form? --- correct answer ---result of rust forming
on the internal pipe and tank surfaces, which may be be made of iron
or steel.
What is pour point? --- correct answer ---the lowest temperature at
which the fuel can be stored and handled.
What is one of the lowest pour point oils? --- correct answer ---No.2
, What is ash content? --- correct answer ---indicates the amount of
noncombustible materials contained in the fuel oil.
What is distillation quality? --- correct answer ---describes the ability
of the oil to become vaporized
Where can oil tanks be placed? --- correct answer ---Above or below
ground and indoor.
What is an oil deaerator? --- correct answer ---an oil piping
component that allows a one-pipe system to function as a two-pipe
system. This is accomplished by connecting two pipes between the
deaerator and the fuel pump on the oil burner, but only one pipe
between the dearator and the oil storage tank. This eliminates the are
problems that are typically found in one-pipe oil supply systems.
How does fuel get to the oil deaerator? --- correct answer ---fuel
travels from the oil tank, through the oil filter, and into the deaerator.
What happens in the oil deaerator? --- correct answer ---any air that
is mixed with the oil is separated from the fuel, allowing fuel to then
pass on to the fuel pump.
