In the event of a tube failure in a boiler, reducing combustion is the appropriate immediate action to take. This response is crucial because a tube failure can compromise the boiler's structural integrity and safety, potentially leading to overheating, pressure surges, and steam release. By reducing combustion, the heat input to the boiler is decreased, which minimizes the risk of further damage or catastrophic failure.

This action helps to stabilize the system's conditions, allowing for safe assessment and repair procedures to begin. It is a preventive measure to avoid escalating the problem, ensuring that the failure does not lead to more severe safety concerns, such as a boiler explosion or steam leak.

Other options, such as increasing fuel feed or turning off the water supply, could potentially exacerbate the situation. Increasing the fuel feed would add more heat to the boiler, further stressing a compromised system, while turning off the water supply could lead to overheating and boiler damage, as the essential cooling and steam generation processes would be interrupted. Notifying the maintenance team is an essential step, but it should follow the immediate action of ensuring safety by reducing the risk from combustion first.
