When using compressed air for light-off, what is the required pressure of the compressed air?

• A. 50 to 75 psig
• B. 70 to 90 psig
• C. 85 to 150 psig
• D. 100 to 120 psig

Answer: (C)

The correct answer is based on the operational requirements when using compressed air for light-off procedures. In many industrial and shipboard environments, the specified pressure range for effective and safe light-off with compressed air is between 85 to 150 psig. This range ensures that the air supply is sufficiently pressurized to effectively support ignition and combustion processes, which is crucial for safe and efficient operation of machinery. Using compressed air within this pressure range helps maintain an adequate flow and ensures that the air can displace any hazardous materials or ensure proper fuel-air mixing during light-off. Lower pressures may not provide enough force to achieve the necessary flow rates, while excessive pressures could risk damaging equipment or creating safety hazards. Hence, 85 to 150 psig is the appropriate choice for ensuring optimal performance and safety when utilizing compressed air for light-off applications.
