New York Low Pressure Boiler COF Practice

What should the pressure relief device be set to activate at?

1. MAWP

2. 30 psi below MAWP

3. 5 psi above MAWP

4. MAWP-10%

The correct answer is: MAWP

The pressure relief device should be set to activate at the Maximum Allowable Working Pressure (MAWP) because this is the maximum safe pressure that the boiler can handle during normal operating conditions. The purpose of the pressure relief device is to prevent overpressure situations that can lead to equipment failure or catastrophic incidents. Setting the activation pressure at MAWP ensures that the device will engage when the system pressure reaches the point where it could potentially exceed safe limits, thereby protecting the integrity of the boiler and preventing harm to personnel and property. It's essential to maintain this setting to meet safety regulations and ensure that the boiler operates within its designated specifications. This understanding also emphasizes the importance of regular maintenance and testing of the relief device to confirm it functions properly at the designated pressure.
