What is the maximum allowable fuel oil temperature at the burner front?

The maximum allowable fuel oil temperature at the burner front is set to ensure safe and efficient combustion. The correct answer is 125 F, as this temperature helps maintain proper fuel viscosity and atomization. If the temperature is too high, it can lead to fuel degradation, increased emissions, and potential combustion issues due to changes in fuel properties. Keeping the fuel oil at or below this temperature ensures optimal performance of the burner system and helps avoid operational problems that could arise from overheating.

Maintaining the fuel oil at this temperature also aligns with standard operating procedures and safety regulations for industrial equipment, ensuring that the burner operates efficiently while minimizing risks to personnel and equipment.
