FDNY COF P-98 test questions &
Answers updated solution
Suction pump - ANS ✔✔ - circulates the oil throughout the system
Suction line - ANS ✔✔ - has to be 6 inches from the bottom of the tank for sediment not to be absorbed
Vacuum gauge - ANS ✔✔ - a device that measures pressure below atmospheric pressure/is used to
indicate to the operator whether there is an obstruction in the suction line
Excessive vacuum readings - ANS ✔✔ - indicate that there is an obstruction in the suction line
Main fuel valve - ANS ✔✔ - is electrically operated and will open or close the line leading to the atomizer
only for oil burners
Carbon and hydrogen - ANS ✔✔ - are the two principal elements of fuel oil
During the combustion process, the carbon content of fuel oil is - ANS ✔✔ - 85%
The hydrogen content of the oil is - ANS ✔✔ - 14%
The air that contacts the oil prior to its leaving the nozzle is referred to as - ANS ✔✔ - Primary air
The introduction of air from the blower or fan into the combustion chamber after the oil has left the
nozzle is referred to as - ANS ✔✔ - secondary air
, Oil burners require approximately - ANS ✔✔ - 2000 cubic feet of air per gallon of oil consumed
During the process of combustion, one part of carbon unites with two parts of oxygen to produce - ANS
✔✔ - carbon dioxide (CO2)
Each time 1 pound of carbon is burned - ANS ✔✔ - 14,544 BTU of heat are liberated
A correctly adjusted oil burner flame will have an - ANS ✔✔ - orange colored flame body with small red
tips
A red, smoky flame is an indication of a - ANS ✔✔ - lack of air
A white, almost dazzling flame is an indication of a great amount of - ANS ✔✔ - excess air
An insufficient air supply is one cause of - ANS ✔✔ - dense, black smoke and soot
Insulated firebrick is lightweight firebrick that becomes - ANS ✔✔ - cherry red 15 seconds after the
burner starts
Diesel generators should be tested at - ANS ✔✔ - minimum monthly
Small portable diesel generators rang from - ANS ✔✔ - 1K VA - 10K VA
Large office complexes, factories, and power stations generators rang from - ANS ✔✔ - 8K VA - 2000K
VA
Approval from the NYC department of buildings and FDNY is required before - ANS ✔✔ - changing any
grade of fuel oil
