Study Notes
Fuel-Oil Transfer Supervision
- A P-98 Certificate of Fitness is mandatory for supervising fuel-oil transfers within buildings.
- The design of the fuel-oil transfer system must consider maximum suction, flow rate, oil piping design, and control strategies.
Fire Classes
- Class A fires are caused by ordinary combustibles like wood, paper, and cloth. Water is effective for extinguishing these fires.
Tank Supervision and Inspections
- Stationary fuel-oil storage tanks require general supervision by a P-98 Certificate of Fitness holder.
- Inspections and testing of tanks and piping must be conducted under the personal supervision of this certificate holder and shall occur weekly.
Compliance and Regulations
- Operating oil-burning equipment requires a certificate of compliance from the NYC Department of Buildings.
- The P-98 C of F is necessary for buildings transporting fuel from lower to upper floors per NYC Fire Code and Mechanical Code.
Combustion and Fuel System
- The oil storage tank supplies oil for combustion in an oil burner, kept inside a dike.
- The suction pump circulates oil through the system, while contaminants, including dirt and sediment, are present in fuel-oil.
Maintenance Equipment
- An oil filter removes most contaminants before oil reaches the burner's strainer, while the suction line must be at least 6 inches above the tank bottom to avoid sediment.
Safety Devices
- Excessive vacuum readings indicate potential obstructions in the suction line.
- A vacuum gauge measures pressure below atmospheric levels, while the main fuel valve shuts down the burner in case of ignition failure.
Oil Burner Operations
- Oil circulation returns through an oil return line, with pressure relief valves improving safety against excessive pressure.
- A leak collector is used to store excess oil and monitor levels.
Combustion Chemistry
- Combustion combines oxygen with combustible fuels, primarily consisting of fuel and oil.
- Around 85% of carbon from fuel unites with oxygen during combustion, forming carbon dioxide and monoxide.
Air Introduction in Combustion
- Primary air contacts oil before it exits the nozzle; secondary air is introduced into the combustion chamber post-nozzle.
Generators and Testing
- Diesel generators, using internal combustion engines, require monthly testing by qualified technicians for efficiency.
- Proper engine operation requires running at 60-75% of maximum load.
Fuel Management and Storage
- Strainers and oil burners are necessary to separate impurities in the oil line.
- A shut-off valve allows flow control for maintenance, while appliances must not change specified fuel grades without NY approval.
Boiler Controls
- Essential controls include low water cut-off, primary relay for flame detection, and a smoke alarm for emission control.
- Steam pressure gauges indicate steam boiler conditions, with a maximum normal pressure not exceeding 15 psi.
Safety Measures
- Glazing due to low combustion can cause efficiency issues, while a defective valve can lead to after-drip conditions, posing fire hazards.
- Clearances between oil equipment and electrical panels must align with NYC Electrical Code standards.
Testing and Extinguishers
- Hydrostatic tests for fuel-oil piping and storage tanks must occur at 150% of maximum pressure.
- Fire extinguishers suitable for fuel-oil fires include Class B and ABC multi-purpose types, located within 30 feet of equipment and checked monthly.
Regulatory Language
- "Should" represents recommendations, while "shall" indicates strict requirements per the Fire Code or FDNY.
