What is the manner in which condensate should drain from a steam supply line into the drainage system?

• A. By using a direct pipe connection
• B. By gravity; indirectly through air gap
• C. Through forced air ventilation
• D. With a syphon effect

Answer: (B)

The correct method for draining condensate from a steam supply line is by gravity, indirectly through an air gap. This approach is essential for maintaining proper drainage and ensuring that condensate flows naturally without the risk of backflow or contamination. Using gravity to drain condensate enables the fluid to move downward towards the drainage system due to the force of gravity, promoting efficient drainage. An air gap is crucial in this scenario as it helps prevent any potential siphoning effect, which could result in backflow of contaminated water into the steam supply system. The air gap allows for the separation required between the condensate line and the drainage system, ensuring that any pressure fluctuations do not compromise the system by allowing the steam and condensate to mix with the drainage water. Other methods, such as direct pipe connections, forced air ventilation, or creating a siphon effect, may not effectively manage the risks associated with drainage systems, such as contamination or improper drainage flow. A direct pipe connection could lead to backflow if not appropriately designed. Forced air ventilation is not a standard method used for condensate drainage and would be impractical in this context. Lastly, relying on a siphon effect could introduce unwanted complications, as siphons can fail or get interrupted, leading to drainage issues
