Question 113Motor Plants - QMED

The correct answer is B) provide a wide range of combustion. A variable capacity, pressure atomizing, fuel oil burner is designed to provide a wide range of combustion by adjusting the fuel flow rate. This allows the burner to operate efficiently across a broad range of load conditions, ensuring complete combustion and minimizing smoke and emissions. The other options are incorrect because: A) maintaining a constant fuel temperature is not the primary function of this type of burner, C) providing a constant fuel return pressure is not the main purpose, and D) while maintaining smokeless fuel oil atomization is important, it is not the overall function of the variable capacity burner.
