Fuel oil must be heated to a specific temperature before entering the combustion process to ensure efficient burning and optimal performance of the boiler system. Raising the fuel oil to around 180 degrees Fahrenheit facilitates better atomization, which is crucial for achieving a fine mist of fuel that promotes more complete combustion.

Heating the fuel oil helps reduce its viscosity, allowing it to flow more easily through fuel lines and pipes. This improved flow is vital for maintaining consistent fuel delivery to the burner system. When the oil is at this temperature, it can respond better to the high-pressure conditions in the combustion chamber, ensuring that the fuel mixes well with air, which leads to improved combustion efficiency and reduced emissions.

While other temperatures might be considered for different types of fuels or specific systems, 180 degrees Fahrenheit is commonly accepted as an effective temperature for preheating fuel oil in standard low-pressure boiler operations.
