What is the ignition temperature of #2 fuel oil?

The ignition temperature of #2 fuel oil is indeed around 500°F. This is the minimum temperature at which the fuel oil will ignite and sustain combustion when exposed to a flame or spark. Understanding this temperature is crucial for oil heat technicians, as it plays a significant role in safe handling, storage, and operation of oil-burning equipment.

When the temperature of #2 fuel oil reaches this ignition point, it vaporizes sufficiently to create a combustible mixture with air, enabling the burning process. This knowledge helps technicians ensure that systems are operating safely and efficiently, reducing the risk of fire hazards.

Other temperatures listed do not accurately reflect the ignition point for #2 fuel oil; temperatures below 500°F are not sufficient for ignition, while those above may indicate conditions that are unnecessary or potentially dangerous. Careful management of operating temperatures ensures safe usage and longevity of heating systems utilizing #2 fuel oil.
