FDNY COF P-98 QUESTIONS WITH CORRECT ANSWERS GRADED A+

1.- Where generally Fuel-oil is used in buildings? What purposes? Is used in Stationary Equipment Two purposes: a) Fuel Emergency Generators b) Fuel Equipment used to heat the building 2.- What COF is required to supervise the Fuel-oil transfer in the building from one floor to another? - P-98 and maintain all qualifications and comply w/ requirements applicable to such certificate holder - The P-98 COF is premise-related 3.- The use of the word should refers to: Policies, procedures and/or best practices recommended by the FDNY, and may not be a codified requirement. 4.- The use of the word shall refers to: Requirement of the Fire Code or the FDNY 5.- Supervision of Fuel-Oil Piping & Storage Operation Shall be under the GENERAL SUPERVISION of P-98: A stationary fuel-oil storage tank, related piping, that is installed on the lowest floor of the building and transfer fuel-oil through piping to another stationary fuel-oil storage tank, or fuel burning equipment, installed above such floor 7.- Maintenance Requirements Fuel-oil storage tanks and piping shall be inspected for any evidence of leaks Weekly 6.- Supervision of Fuel-Oil Piping & Storage Operation Shall be under the PERSONAL SUPERVISION of P-98 COF Periodic Inspection and Testing of tanks and piping 8.- Maintenance Requirements Fuel-oil storage tanks shall have their float switches tested to ensure that they are in good working order at least Weekly 9.- Licences & Certificates No oil burning equipment may operated until a) Certificate of Compliance has been issued by NYCDOB b) Air pollution control code requirements NYCDEP c) Permit for the Storage & use of fuel-oil issued by FDNY 10.- Licences & Certificates Pursuant to the New NYC Fire Code & Mechanical Codes stated that The COF is required for all existing and new buildings where fuel is being transported from the lowest levels to tanks or equipment on upper floors 11.- Oil Circulation in the System Diagram #1 The process of oil circulation from the tank at the lowest floor of a building to the burner on the floor above such floor through the pump. 12.- Oil Circulation in the System Oil storage tank Provides the supply of oil for combustion in the oil burner. It is inside a dike. In case of a leak the diked area will contain the oil. In its normal condition, #2 fuel-oil is thin and light and is easily pumped through the circulation system 13.- Oil Circulation in the System A Suction pump Circulates the oil throughout the system. Dirt and sediment are present in the fuel-oil coming from the oil storage tank. The oil filter removes most of these contaminants from the oil before the oil reaches the burner's strainer. 14.- Oil Circulation in the System The Suction Line Has to be 6 inches from the bottom of the tank for sediments not to be absorbed. The vacuum gauge is a device that measures pressure below atmospheric pressure. Excessive vacuum readings 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. This permits the operator to clean the filter/strainer or to perform other maintenance 15.- Oil Circulation in the System Main Fuel Valve 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. 16.- Oil Circulation in the System A Back Pressure Relief Valve Oil circulates through the piping system back to the storage tank through the oil return line. A back pressure relief valve is provided for safety if the pressure becomes too great. Day tanks may be located throughout the building above the lowest floor 17.- Oil Circulation in the System A Separate Pump Required for each day tank to supply each floor. In case of a leak in the piping, leak collector is provided. Leak collector is stored by the storage tank. It has a oil level gauge which shows the amount collected 18.- Oil Circulation in the System Level Gauge A gauge will show how much fuel oil is inside a main storage tank/day tank. 19.- Oil Burner Operation Combustion Is the chemical union of the oxygen in the air with combustible elements in fuel-oil (hydrogen and carbon). The end result of this process is the production of heat energy 20.- Oil Burner Operation Oil Firing Equipment Used to liberate heat energy from fuel-oil. Oil burners are the principal components of the oil firing equipment and provide the means of supporting the process of combustion. 21.- Oil Burner Operation Two principal elements of fuel-oil Carbon and hydrogen. During the combustion process, the carbon content of fuel-oil (about 85%) unites with the oxygen in the air and forms carbon dioxide and carbon monoxide. The hydrogen content of the oil (about 14%) unites with the oxygen and produces water. The objective is to have a complete combustion process 22.- Oil Burner Operation In order to support combustion It must be changed to a gas or vapor and mixed with air 23.- Oil Burner Operation The Oil burner Primarily a 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. 24.- Oil Burner Operation Atomizing Oil This process of breaking down or atomizing the oil is to ensure prompt ignition and rapid combustion. Although there are various types of oil burners, i.e. generator or boiler, they all vaporize or atomize the oil before it enters the combustion chamber where it is mixed with air in predetermined proportions. 25.- Oil Burner Operation Oil burner uses an Oil Pump 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. 26.- Oil Burner Operation Secondary 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 "secondary air". Every brand of oil burner is essentially different from that of other manufacturers 27.- Oil Burner Operation The Diesel 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. 28.- Oil Burner Operation Oil burners required approximately 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 29.- Oil Burner Operation The mixture of air and fuel in the burner must be strictly controlled 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. 30.- Oil Burner Operation Carbon Dioxide 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. 31.- Oil Burner Operation Incomplete Combustion 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. 32.- Oil Burner Operation If the proper amount of air has been thoroughly mixed with the oil, and the temperature of the flame is correct The free carbon burns completely. A correctly adjusted oil burner flame will have an: Orange-colored flame body with small red tips. The tips will be slightly cloudy.
