Why is it important for the oil burner to shut down at a specific steam pressure?

The importance of the oil burner shutting down at a specific steam pressure primarily relates to preventing equipment damage. Oil burners and boilers are designed to operate within specific pressure limits, and exceeding these limits can lead to excessive stress on components, potential leaks, or even catastrophic failures. When the steam pressure reaches a predetermined threshold, the burner must shut down to ensure the safety of the system and to protect vital components from overheating or bursting, which can occur if the pressure is not properly managed. This preventive measure helps maintain the integrity and reliability of the entire heating system.

Although conserving fuel, enhancing combustion efficiency, and maintaining boiler cleanliness are also important factors in the operation of an oil burner, the immediate priority in this context is to protect the equipment from damage that could arise from excessive steam pressure.
