What is the primary purpose of a boiler's MAWP?

• A. To measure efficiency
• B. To indicate maximum allowable working pressure
• C. To assess heat transfer capability
• D. To provide a standard for maintenance

Answer: (B)

The primary purpose of a boiler's Maximum Allowable Working Pressure (MAWP) is to indicate the maximum pressure at which the boiler is authorized to operate safely. This parameter is crucial for ensuring the safe design and operation of the boiler, as it takes into account factors such as the material properties, thickness, and construction methods used in the boiler's design. Operating above the MAWP can lead to unsafe conditions, including the risk of failure or explosion, making adherence to this limit essential for the safety of both the equipment and personnel. Therefore, understanding and respecting the MAWP is vital for the safe operation of any boiler system. Other options like measuring efficiency, assessing heat transfer capability, or providing a standard for maintenance, while important aspects of boiler operations and performance, do not directly relate to the MAWP's fundamental role in safety and operational limits.
