Baffles are used in the steam and water drum of water tube boilers to _____.

Baffles are crucial components in the steam and water drum of water tube boilers because they play a significant role in maintaining the quality of steam generated within the system. By preventing water carry over with the steam, baffles ensure that only dry steam is delivered to the steam headers, which is vital for the efficient operation of the steam system. If water were to carry over with the steam, it could lead to a variety of issues such as decreased thermal efficiency, damage to steam-using equipment, and potential safety hazards.

The presence of baffles disrupts the flow of water, helping to separate steam from water and allowing for the dry steam to rise while retaining the water in the drum. This separation is essential for the reliable performance of the boiler and for maintaining the desired steam quality, which is why preventing water carry over is the primary function of baffles in this context.
