P98 Exam Questions & Answers(RATED A+)

Fuel-oil is generally used in buildings in stationary equipment for two purposes -ANSWER fuel emergency generators or to fuel equipment used to heat the building. the person supervising the Fuel-Oil Transfer in the Building from one floor to another must hold -ANSWER P-98 Certificate of Fitness. Certificate of Fitness holders must maintain all qualifications and comply with all requirements applicable to such certificate holders throughout the term of their certificate. The P-98 Certificate of Fitness is premise-related. The use of the word "should" throughout these study materials generally refers to -ANSWER policies, procedures and/or best practices recommended by the FDNY, and may not be a codified requirement. The use of the word "shall" throughout these study materials generally refers -ANSWER to a requirement of the Fire Code or the FDNY. 3.1 SUPERVISION OF FUEL-OIL PIPING AND STORAGE OPERATIO -ANSWER A stationary fuel-oil storage tank, and related piping, that is installed on the lowest floor of a building and that transfers fuel-oil through piping to another stationary fuel-oil storage tank, or to fuel-oil burning equipment, installed above such floor, shall be under the -ANSWER the GENERAL SUPERVISION of a P-98 Certificate of Fitness holder The periodic inspection and testing of such tanks and piping shall be conducted under the -ANSWER PERSONAL SUPERVISION of such P-98 Certificate of Fitness holder. Fuel-oil storage tanks and piping systems shall be inspected at least once ----for any evidence of leaks -ANSWER Weekly Fuel-oil storage tanks subject to this section shall have their float switches tested at least once ---- to ensure that they are in good working order. -ANSWER Weekly Who is required for all existing and new buildings where fuel is being transported from the lowest levels to tanks or equipment on upper floors pursuant to the new NYC Fire Code and Mechanical Codes? -ANSWER The COF holder The oil storage tank -ANSWER provides the supply of oil for combustion in the oil burner The oil storage tank is inside a ---- -ANSWER dike In case of a leak the ---- area will contain the oil -ANSWER diked In its normal condition, #2 oil fuel is -ANSWER thin and light and is easily pumped through the circulation system. A suction pump does what? -ANSWER circulates the oil throughout the system. What are present in the fuel-oil coming from the oil storage tank? -ANSWER Dirt and sediment The ---- removes most of these contaminants from the oil before the oil reaches the burner's strainer. -ANSWER oil filter The suction line has to be ---- inches from the bottom of the tank for sediments not to be absorbed -ANSWER 6 The vacuum gauge -ANSWER a device that measures pressure below atmospheric pressure. Excessive vacuum readings (in the vacuum gauge) indicate that -ANSWER there is an obstruction in the suction line (such as dirty oil strainer). When the vacuum gauge shows obstruction in the suction line it can be stopped by closing the -ANSWER shut off valve Closing the shut off valve -ANSWER permits the operator to clean the filter/strainer or to perform other maintenance. The main fuel valve is -ANSWER electrically operated and will open or close the line leading to the atomizer only for oil burners. It will shut down the burner system if there is a failure of ignition or combustion. The oil return line -ANSWER Oil circulates through the piping system back to the storage tank through it (the oil return line) A ---- is provided for safety if the pressure becomes too great. -ANSWER back pressure relief valve Day tanks may be located -ANSWER throughout the building above the lowest floor. A ---- required for each day tank to supply each floor. -ANSWER separate pump In case of a leak in the piping, a ---- is provided -ANSWER leak collector Leak collector is stored by -ANSWER the storage tank The leak collector has an ---- which shows the amount of oil collected -ANSWER oil level gauge A gauge will show -ANSWER ow much fuel oil is inside a main storage tank/day tank Combustion is the -ANSWER chemical union of the oxygen in the air with combustible elements in fuel-oil (hydrogen and carbon). The end result of combustion is -ANSWER heat energy Oil firing equipment -ANSWER is used to liberate heat energy from fuel-oil. Oil burners -ANSWER the principal components of the oil firing equipment and provide the means of supporting the process of combustion. Two principal elements of fuel oil -ANSWER Carbon and hydrogen During the combustion process the carbon content of fuel oil unites w/ oxygen in the air and forms -ANSWER carbon dioxide and carbon monoxide The hydrogen content of the oil unites with the oxygen and produces ---- during combustion -ANSWER water The objective of complete combustion is met when -ANSWER fuel oil combines with the greatest possible amount of oxygen. Carbon % of fuel oil -ANSWER 85 Hydrogen content of oil -ANSWER about 14 Fuel oil must be changed to -------- in order to support combustion. -ANSWER a gas or vapor and mixed with air An oil burner is primarily a -ANSWER device for processing the liquid fuel for combustion by accelerating the change from liquid to a vapor that can be mixed with air and burned. This process of breaking down or atomizing the oil is necessary to ensure ------- and ------- -ANSWER prompt ignition and rapid combustion Although there are various types of oil burners, i.e. generator or boiler, they all -ANSWER vaporize or atomize the oil before it enters the combustion chamber where it is mixed with air in predetermined proportions. An oil burner uses an oil pump and mixes air and oil within -ANSWER the nozzle itself In oil burners, the oil and air mixture is delivered to the nozzle at a pressure dependent upon the -ANSWER make of the burner The air that contacts the oil prior to its leaving the nozzle is referred to as -ANSWER 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 -ANSWER secondary air Every brand of oil burner is essentially -ANSWER different from that of other manufacturers ----generators 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. -ANSWER Diesel Oil burners require approximately ---- cubic feet of air per gallon of oil consumed. -ANSWER 2000 The mixture of oil and air is sprayed in vapor form into a ------ where combustion takes place -ANSWER Firebox aka combustion chamber The mixture of air and fuel in the burner must be strictly controlled; otherwise it could become an -ANSWER explosive mixture During the process of combustion, --- part of ----unites with --- parts of ---- to produce carbon dioxide (CO2). -ANSWER 1/carbon 2/oxygen Each time 1 pound of carbon is burned --- BTU of heat are liberate -ANSWER 14,544 ----is recognized as the end product of complete combustion -ANSWER Carbon dioxide Should fuel be supplied without the proper amount of ----, carbon dioxide and soot will be produced. -ANSWER oxygen Incomplete combustion is produced at ---- BTU at hear heat liberate -ANSWER 4,480 ---- is considered as the end product of incomplete combustion. -ANSWER Carbon monoxide In addition to being inefficient in the production of heat, the presence of carbon monoxide is -ANSWER highly dangerous If the proper amount of air has been thoroughly mixed with the oil, and the temperature of the flame i
