What should be done if oil is found in a boiler?

When oil is found in a boiler, using an alkaline detergent to clean the boiler is essential. The presence of oil can indicate contamination, which affects the efficiency and safety of the boiler operation. Oil residues can lead to various issues, such as fouling of heat transfer surfaces, which can cause overheating, reduced efficiency, and even damage to the boiler.

Cleaning with an alkaline detergent is the recommended approach because it effectively breaks down and emulsifies the oil, allowing it to be washed away. This type of detergent is designed to penetrate and remove hydrocarbon residues, making the cleaning process more effective. After cleaning, the boiler can be properly inspected and maintained, ensuring it operates safely and efficiently.

Ignoring the oil or simply hoping it will dissipate is not a viable option, as it can lead to increased operational risks and costs. Increasing the temperature might temporarily reduce the thickness of the oil but does not resolve the underlying contamination issue. Changing the oil without addressing the boiler contamination can lead to premature degradation and possibly necessitate further repairs or maintenance. Thus, cleaning the boiler using alkaline detergent is the most effective solution to manage the situation.
