Power Engineering 2B2: Chapters 1-2 Test with Answers Rated A
What is distillation? Separation of oil into its constituent parts.
What are residual oils? The bottoms left after distillation.
The use of heat and pressure to decompose oil into a
What is cracking? new series of hydrocarbons, changing the hydrocarbon
structure.
Specific Gravity is measured in: Degrees API (American Petroleum Institute).
Degree API = ( 141 / Specific gravity at 15.6'C/15.6C) - 131.5
The specific gravity of any petroleum product bears a
heating value.
direct relationship to:
The time taken for a standard quantity of oil to flow
Viscosity is the measurement of:
through a standard orifice.
Types of Viscosimeters include: Saybolt, redwood, and Engler.
Light distillate, used for vaporizing burners, highly volatile,
Grade 1 Fuels:
minimal residue as it evaporates.
Slightly heavier than Grade 1, used for atomizing burners,
Grade 2 Fuels:
easier to handle than residual oils but more costly.
A heavy distillate or a heavy residual and distillate blend,
Grade 4 (light) Fuels: requires pressure to be atomized at the burner, little to no
heating to be pumped.
A heavy distillate or heavy residual and distillate blend,
Grade 4 (heavy) Fuels: requires little heating except in extreme cold, used with
atomizing burners.
Mid viscosity residual fuel, usually requires preheating
Grade 5 (light) Fuels:
and atomizing types of burners.
Heavier than Grade 5 light, used in similar applications.
Grade 5 (heavy) Fuels:
Some heating required in cold ambient temperatures.
Grade 6 Fuels are called: Bunker C
Grade 6 Fuels: 1/9
, Have high viscosity, requires heating for storage and
pumping as well as additional heating for atomizing at the
burners.
87.3% Carbon, 10.8% Hydrogen, 1.2% Sulphur, 0.2% Ni-
Bunker C coal is:
trogen.
Grade 6 Fuels have a Sulphur content of: 0.7 - 3.5 % (2016 cap of 3.5%)
The temperature at which a substance gives ott enough
Flash Point is defined as:
vapour to make a flammable mixture with air.
The temperature below which the substance will NO
Pour point is defined as:
LONGER flow.
Water and sediment content in oil should not be more
2%.

Attached to the vent to reduce possibility of tank explo-
Flame Arrestors are:
sions.
Heating oil in the suction box area to a minimum of 38 C
Steam heating coils are used for:
so it can be pumped to the oil heaters.
Mesh size of filter media depends on the: Type of fuel being used.
The filter size used on Grade 2 fuel is: 100 mesh filter.
The filter size used on Grade 6 fuel is: 10 mesh filter.
Fuel pumps are usually positive displacement pumps, and A pressure relief valve that directs oil back to the storage

Fuel pumps use the following types: gear type or rotary screw type
Mechanical atomization requires pressures of: 345 to 1725 kPa.
Steam atomization requires pressures of: 12 to 860 kPa.
Steam atomization requires that 38 C oil must be heated
85 C.
