What is the purpose of the water drum in a boiler system?

The purpose of the water drum in a boiler system is to evenly distribute water to the main generating tubes. This function is crucial for ensuring that the water entering the tubes is properly balanced and at the correct temperature to facilitate efficient steam generation. By maintaining an even distribution, the water drum helps to optimize heat transfer within the boiler, which is essential for effective steam production.

In a boiler, uneven water distribution can lead to issues such as overheating or localized boiling, potentially damaging the tubes and reducing overall efficiency. The water drum serves as a reservoir that not only provides a steady supply of water but also aids in managing the pressure and temperature conditions required for the system to operate safely and efficiently.
