What is the minimum size of a drain on a super heater?

• A. 2 inches
• B. 1 inch
• C. 3 inches
• D. 1.5 inches

Answer: (B)

The minimum size of a drain on a super heater being one inch is based on the need to effectively manage and remove any accumulated moisture or condensate that may develop in the super heater during operation. Super heaters are designed to increase the temperature of steam generated in a boiler, and any entrapped water can lead to inefficiencies or even damage. Using this minimum size helps ensure adequate drainage capacity while allowing for adequate flow rates, which is critical to maintaining the efficiency and safety of the boiler system. A one-inch drain is typically sufficient to handle the drainage requirements without risking obstruction or backflow, thus promoting optimal performance of the super heater and preventing potential operational issues.
