What is the purpose of the vortex eliminator in the steam drum?

• A. To increase pressure
• B. To reduce the swirling motion of water entering downcomers
• C. To enhance steam quality
• D. To speed up the boiling process

Answer: (B)

The purpose of the vortex eliminator in the steam drum is to reduce the swirling motion of water entering the downcomers. In a steam drum, it is crucial that the water flows smoothly and steadily into the downcomers to ensure efficient circulation in the steam generation process. If water enters the downcomers with a swirling motion, it can lead to uneven flow, which may cause issues such as poor heat transfer and reduced system efficiency. By eliminating or reducing this vortex effect, the design allows for a more controlled and streamlined flow of water, ensuring that the water is properly fed into the downcomers, thereby maintaining optimal operation of the boiler system. Additionally, this helps minimize issues like water hammer and other hydraulic disturbances, ensuring the overall stability and safety of the system.
