What is the pressure range for pressure-atomizing burners using light fuel oil?

Pressure-atomizing burners operate by using pressure to effectively spray fuel oil into the combustion chamber for efficient burning. Light fuel oil, commonly used in residential and commercial heating applications, requires a specific pressure range for optimal atomization and combustion efficiency.

The correct answer indicates a pressure range of 550 to 700 kPa, which is suitable for pressure-atomizing burners. This pressure ensures that the oil is atomized properly into fine droplets, allowing for a more complete combustion process, higher efficiency, and reduced emissions.

Burners that operate outside this specified range might experience issues such as inadequate atomization or excessive fuel usage, leading to incomplete combustion. Thus, the selection of the pressure range is critical for maintaining the efficiency and reliability of the burner system.
