What should be checked before starting a boiler operation?

Before starting a boiler operation, it is crucial to check the water feed systems to ensure that the boiler has an adequate supply of water for efficient and safe operation. The water feed system is responsible for delivering water to the boiler, which is essential for creating steam. Insufficient water can lead to overheating, boiler failure, or even a catastrophic event such as an explosion.

By confirming that the water feed systems are functioning correctly, operators can prevent these serious issues and ensure that the boiler will operate under safe conditions. This involves checking the water levels, ensuring there are no leaks or blockages in the system, and verifying that pumps and valves are operational.

The other options, while important for overall boiler operation and efficiency, focus on specific aspects that do not take precedence over ensuring a reliable water feed. Fuel levels, flue gas composition, and surge tank connections are all necessary checks, but without the water feed system being operational, the boiler cannot run safely at all.
