FDNY P98 COF EXAM WITH COMPLETE SOLUTIONS
100% VERIFIED!!
Suction pump
circular the oil with in the system
Suction line
has to be 6 inches from the bottom of the tank for sediment not to be absorb
Vacuum gauge
a device that measures pressure below atmospheric pressure / is used to indicate to the
operator wether there is an
obstruction in the suction line
Excessive vacuum reading
indicate that ther is an obstruction in the suction line
Main fuel valve
is electrically operated and will open or close the line leading to the atomizer only for oil
burners
Carbon and hydrogen
are the two principal elements of fuel oil
During the combustion process, the carbon content of fuel oil is
85%
The hydrogen content of the oil is
14%
, The air that contacts the oil prior to its leaving the nozzle is referred to as
Primary air
the introduction of air from the blower or fan into the combustion chamber after the oil
has left the nozzle is called
secondary air
Oil burners require about
2000 cubic feet of air per gallon of oil burned
In combustion, one atom of carbon unites with two atoms of oxygen to form
carbon dioxide (CO2)
Each time 1 pound of carbon is burned
14,544 BTU of heat are liberated
A properly adjusted oil burner flame will have an
orange colored flame body with small red tips
