OIL BURNER TECHNICIAN 3 (OBT3)
CERTIFICATION
what are the two main components in fuel oil - CORRECT-ANSWERS--
hydrogen and carbon >>> which form various hydrocarbon compounds.
All fuel oils are ultimately derived from crude oil, a complex mixture
consisting primarily of these two elements.
what percent of fuel oil do hydrogen and carbon make up - CORRECT-
ANSWERS--96 to 99%
what does distillation do - CORRECT-ANSWERS--separates crude oil into
component fractions >>> separate the components of a liquid mixture
based on their different boiling points. It is a physical separation process,
not a chemical reaction.
, what happens after distillation in the refining process - CORRECT-
ANSWERS--catalytic cracking >>> the refining process continues with
several steps designed to further process and enhance these fractions.
These subsequent steps serve two main purposes: to convert lower-value
fractions into more valuable products and to remove impurities
what are the two phases in the refining process - CORRECT-ANSWERS--
distillation and catalytic cracking
what are the categories of refined fuel oils - CORRECT-ANSWERS--
distillation and residuals
what is the flash point - CORRECT-ANSWERS--the lowest temperature that
No.2 oil can ignite but it wont stay lit
what is the lowest temperature flash piont can be for NO. 2 fuel oil -
CORRECT-ANSWERS--104F
what is fire point/ ignition point - CORRECT-ANSWERS--the lowest temp
and rapid combustion will take place in air
what is No.2 oils fire point - CORRECT-ANSWERS--437F
what is pour point - CORRECT-ANSWERS--the point at which the fuel oil
barely flows
what will happen if you mix No.1 fuel oil with No.2 fuel oil - CORRECT-
ANSWERS--the pour point will lower for the No. 2 fuel oil
what is the cloud point - CORRECT-ANSWERS--the temperature at which
crystals will start to form in the fuel oil
