Which component is essential for a boiler's operation to prevent backflow of steam or water?

Expansion tank
Backflow preventer
Safety valve
Pressure gauge

The correct answer is: Backflow preventer

The essential component for preventing backflow of steam or water in a boiler system is the backflow preventer. This device is specifically designed to stop the reverse flow of water or steam, which can occur due to pressure changes or system malfunctions. By ensuring that the flow remains in the intended direction, backflow preventers help maintain system integrity and safety, reducing the risk of contamination and equipment damage. In contrast, while an expansion tank helps manage pressure changes in a heating system and allows for thermal expansion of water, it does not prevent backflow. The safety valve is crucial for releasing excess pressure to prevent explosions but does not specifically address backflow issues. A pressure gauge is important for monitoring system pressure but does not actively prevent backflow either. Therefore, the backflow preventer is vital for ensuring safe and efficient boiler operation.
