1.- Where generally *Fuel-oil is used in buildings?* What purposes?* - ANSWER- Is used in *Stationary Equipments*, 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?* - ANSWER- *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: - ANSWER- *Polices, procedures and / or best practices recommended by the FDNY* 4.- The use of the word *shall* refers to: - ANSWER- *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: - ANSWER- *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* 6.- *Supervision of Fuel-Oil Piping & Storage Operation* Shall be under the *PERSONAL SUPERVISION* of P-98 COF shall be? - ANSWER- *Periodic Inspection and Testing of tanks and piping* 7.- *Maintenance Requirements* Fuel-oil storage tanks and piping *shall be inspected* for any evidence of leaks? - ANSWER- *Weekly* 8.- *Maintenance Requirements* Fuel-oil storage tanks *shall have their float switches tested* to ensure that they are in good working order at least? - ANSWER- *Weekly* 9.- *Licences & Certificates* *No* oil burning equipment *may operated until?* - ANSWER- 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? - ANSWER- *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* 12.- *Oil Circulation in the System* What the *oil storage tank* do? - ANSWER- *Provides the supply of oil for combustion in the oil burner. It's inside a dike. In case of leak the diked area will contain the oil.* 13.- *Oil Circulation in the System* How is the #2 fuel-oil in its *normal condition*? - ANSWER- *Is thin and light and is easily pumped through the circulation system.* 14.- *Oil Circulation in the System* *What the suction pump do?* - ANSWER- *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.* 15.- *Oil Circulation in the System* How many inches has to be the *SUCTION LINE?* - 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?* - ANSWER- *A device that measures pressure below atmospheric pressure.* 17.- *Oil Circulation in the System* *Excessive vacuum readings* means? - 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.?* - ANSWER- Flow of oil *STOP* *This permits the operator to clean the filter/strainer or to perform other maintenance* 21.- *Oil Circulation in the System* How operated the *Main Fuel Valve?* - ANSWER- *The main fuel valve is electrically operated and will open or close the line leading to the atomizer* only for oil burners. 22.- *Oil Circulation in the System* The *Main Fuel Valve...* - ANSWER- *It will SHUT DOWN the burner system if there is a failure of ignition or combustion* 23.- *Oil Circulation in the System* *Oil circulates through the piping system back* to....? - ANSWER- *The storage tank through the oil return line* 24.- *Oil Circulation in the System* For Safety is provide a *Back Pressure Relief Valve* - ANSWER- *If the pressure becomes too great...* 25.- *Oil Circulation in the System* Where is located a *Day Tank*? - ANSWER- *May be located throughout the building above the lowest floor* 27.- *Oil Circulation in the System* Is required a *Separate pump*? - ANSWER- *Yes, is required for each* DAY TANK *to supply each floor* 28.- *Oil Circulation in the System* In case of a *leak in the piping.....?* - ANSWER- *Leak collector is provided. Leak collector is stored by the storage tank* 30.- *Oil Circulation in the System* Leak collector has a *gauge?* - ANSWER- *Yes, It has a oil level gauge which shows the amount collected.* *A gauge will show how much oil is inside a main storage tank/day tank* 33.- *Oil Burner Operation* What is a *combustion?* - ANSWER- *Combustion is the chemical union of the oxygen in the air with combustible elements in fuel-oil* (hydrogen and carbon). 34.- *Oil Burner Operation* What is the *end result of combustion?* - ANSWER- *The production of heat energy. Oil firing equipment is used to liberate heat energy from fuel-oil.* 35.- *Oil Burner Operation* The *principal components* of the oil *firing equipment?* - ANSWER- *Oil burners are the principal components of the oil firing equipment and provide the means of supporting the process of combustion.* 36.- *Oil Burner Operation* What are the *two principal elements of fuel-oil?* - ANSWER- 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* 37.- *Oil Burner Operation*
