The oil filter removes most of these contaminants from the oil before the oil reaches the burner's strainer.* 15.- *Oil Circulation in the System* How many inches has to be the *SUCTION LINE?* -------- Correct Answer -------- *6 inches from the bottom of the tank for sediments not to be absorbed* 16.- *Oil Circulation in the System* What is the *vacuum gauge?* -------- Correct Answer -------- *A device that measures pressure below atmospheric pressure.* 17.- *Oil Circulation in the System* *Excessive vacuum readings* means? -------- Correct Answer -------- *Indicate that there is an obstruction in the suction line (such as dirty oil strainer) when this occurs the flow of oil can be stopped by closing the shut-off valve.* 18.- *Oil Circulation in the System* Closing the *shut-off valve.?* -------- Correct Answer -------- Flow of oil *STOP* *This permits the operator to clean the filter/strainer or to perform other maintenance* 19.- *Oil Circulation in the System* 40.- *Oil Burner Operation* Oil burner uses an *oil pump?* -------- Correct Answer -------- *An oil burner uses an oil pump and mixes air and oil within the nozzle itself. In oil burners, the oil and air mixture is delivered to the nozzle at a pressure dependent upon the make of the burner. The air that contacts the oil prior to its leaving the nozzle is referred to as primary air.* 41.- *Oil Burner Operation* What is *Secondary air*? -------- Correct Answer -------- *The introduction of air from the blower or fan into the combustion chamber after the oil has left the nozzle is referred to as "secondary air". Every brand of oil burner is essentially different from that of other manufacturers* 42.- *Oil Burner Operation* The *Diesel generators* -------- Correct Answer -------- *use injection nozzles without primary air, thus it is important that an operator of a system understand the functions of his/her particular system completely.* 43.- *Oil Burner Operation* Oil burners *required approximately?* -------- Correct Answer -------- *2000 cubic feet of air per gallon of oil consumed. The mixture of oil and air is sprayed in vapor form into a firebox area (the combustion chamber) where combustion takes place* 44.- *Oil Burner Operation* Why the mixture of air and fuel in the burner must be *strictly controlled?* -------- Correct Answer -------- *Otherwise it could become an explosive mixture. During the process of combustion, one part of carbon unites with two parts of oxygen to produce carbon dioxide (CO2). Each time 1 pound of carbon is burned, 14,544 BTU of heat are liberated.* 45.- *Oil Burner Operation* What is recognized as the *end product of complete combustion?* -------- Correct Answer -------- "Carbon dioxide" *Is recognized as the end product of complete combustion. Should fuel be supplied without the proper amount of oxygen, carbon dioxide and soot will be produced. It would be produced at 4,480 BTU at heat liberated.* 46.- *Oil Burner Operation* Product of *incomplete combustion?* -------- Correct Answer -------- Carbon monoxide *Is considered as the end product of incomplete combustion. In addition to being inefficient in the production of heat, the presence of carbon monoxide is highly dangerous.* 47.- *Oil Burner Operation* What happens? *If the proper amount of air has been thoroughly mixed with the oil, and the temperature of the flame is correct,....* -------- Correct Answer -------- The free carbon burns completely.

The tips will be slightly cloudy.* 48.- *Oil Burner Operation* Indication *Lack of air?* -------- Correct Answer -------- *A red, smoky flame* 49.- *Oil Burner Operation* Indication *Excess of air?* -------- Correct Answer -------- *A white, almost dazzling flame is an indication of a great amount of excess air.* 50.- *Oil Burner Operation* An *insufficient air supply?* -------- Correct Answer -------- *Is one cause of dense, black smoke and soot; an excessive air supply can put out the flame.* 51.- *Oil Burner Operation* What happens when the *oil spray entering a combustion chamber?* -------- Correct Answer -------- *It burns in suspension. If any part of the spray mixture contacts the walls of a combustion chamber, it will cause a smoky fire. Over a period of time carbon deposits may build up in the combustion chamber and cause a burner failure.* 52.- *Oil Burner Operation* The *Insulated firebrick?* -------- Correct Answer -------- *Makes up the walls of a combustion chamber. Insulated firebrick is lightweight firebrick that becomes cherry red 15 seconds after the burner starts.* 53.- *Oil Burner Operation* The *refractory material in a combustion chamber?* -------- Correct Answer -------- *Should be closed to the flame and the oil should be burned by the reflected heat. Reflected heat, which increases combustion efficiency, is heat that is reflected back into the combustion chamber and maintains the fire after the ignition is turned off.* 54.- *Oil Burner Operation* The *Diesel generators* ......? -------- Correct Answer -------- 1.- *Operate differently. They have an internal combustion engine. Air is compressed by a piston and diesel fuel is injected into the cylinder. The mixture ignites and turns the engine. Insufficient compression air or a clogged ignition nozzle will result in improper combustion. The output will be black smoke and excessive vibration of the engine. Diesel generators should be* tested at minimum monthly 55.- *Oil Burner Operation* The *Generators.......* -------- Correct Answer -------- 2.- *........ are used as an emergency power supply if the grid fails. They range from 1k VA - 10k VA for small portable diesel generators and 8kVA - 2000k VA for large office complexes, factories and power stations. Diesel generators also provide back up power to utility grids. Power failures are particularly critical for hospitals and large offices. Computer service centers have emergency power generators which are typically powered by diesel fuel and configured to start automatically, as soon as a power failure occurs. Power generators are selected based on the load they are intended to supply. Ideally diesel engines should run at least around 60-75% of their maximum rated load, and at around 75% of their maximum speed, and* "MUST BE TEST RUN EVERY MONTH TO AVOID DAMAGE" *under certain conditions that occur when an engine is left idling as a 'standby' generating unit ready to run up when needed.* 56.- *Oil Burner Operation* The *Low Voltage Battery for Generator* -------- Correct Answer -------- 57.- *Oil Burner Operation* Fuel-oil *several grades?* -------- Correct Answer -------- *#1 fuel-oil, to diesel oil or #2 fuel-oil; to the heavier #4, #5, and #6 fuel-oils.
