What is the significance of the 150 psig auxiliary steam system?

• A. It's a backup steam supply
• B. It powers the superheater protection steam
• C. It regulates feed water supply
• D. It raises the operating temperature of the boiler

Answer: (B)

The significance of the 150 psig auxiliary steam system primarily lies in its role in powering the superheater protection steam. The superheater is critical in a steam boiler system, as it elevates the temperature of the steam before it is delivered to the turbines. This elevated temperature enhances the efficiency of the system by increasing the heat energy available for converting to mechanical energy, which is essential for propulsion and generating power. By providing protection steam, the auxiliary steam system helps maintain the operational integrity and safety of the superheater. When the superheater is at risk of overheating or other operational issues, this auxiliary steam serves as a safeguard to ensure the superheater operates within safe temperature limits, thereby preventing potential damage or failure. This makes the auxiliary steam system not just a supplementary function but a vital component in maintaining the overall safety and efficiency of the boiler system, ultimately supporting the effectiveness of the steam being used for various operational needs.
