True or False? The capacity of the air delivery system determines the firing rate of a fuel oil burner.

The statement is true because the capacity of the air delivery system is essential for the proper functioning of a fuel oil burner. The firing rate of the burner depends on the amount of air mixed with the fuel oil for combustion. An adequate air delivery system ensures that there is enough oxygen available for efficient combustion, which optimizes the burner’s performance and efficiency.

When the air delivery system is well-designed and matches the needs of the burner, it allows for the necessary combustion process to occur at the rated firing rate. If the air delivery capacity is insufficient or mismatched, it can lead to incomplete combustion, increased emissions, and potential damage to the burner or system.

This is not a situation that is exclusively governed by specific models or limited to maintenance periods; it is a fundamental characteristic of how combustion systems are designed to operate for fuel oil burners across various applications. Therefore, the capacity of the air delivery system is indeed a determining factor in the firing rate of a fuel oil burner.
