What is the maximum ABMA TDS limit for low pressure boilers (less than 300 psi)?

• A. 2500 ppm
• B. 3500 ppm
• C. 5000 ppm
• D. 7000 ppm

Answer: (B)

The maximum TDS (Total Dissolved Solids) limit for low pressure boilers, generally classified as those operating below 300 psi, is established by various guidelines, including those from the American Boiler Manufacturers Association (ABMA). For low pressure boilers, the acceptable TDS level is typically set at 3500 ppm. Maintaining TDS within this limit is crucial to avoid issues such as scaling, corrosion, and poor steam quality. Higher TDS levels can lead to increased deposits on heat transfer surfaces, reduced efficiency, and ultimately, operational issues. Monitoring and controlling TDS is an essential aspect of water treatment in boiler operations, as it ensures that the boiler can operate effectively and safely, thereby optimizing performance and extending its lifespan.
