Which two elements are the principal components of fuel oil?

Oxygen and nitrogen
Hydrogen and carbon
Carbon and helium
Hydrogen and sulfur

The correct answer is: Hydrogen and carbon

The principal components of fuel oil are hydrogen and carbon. This is because fuel oil is a hydrocarbon, which means it is primarily composed of hydrogen and carbon atoms. These elements play a critical role in the combustion process; when fuel oil is burned, it reacts with oxygen from the air to produce heat, carbon dioxide, and water vapor, thereby releasing energy. The presence of hydrogen allows for the production of water vapor during combustion, while carbon contributes to the formation of carbon dioxide. This composition is fundamental to understanding fuel properties, energy content, and environmental impacts when fuel oil is used in combustion systems. Understanding the correct elemental composition of fuels, like fuel oil, is vital for ensuring efficient combustion and compliance with safety and environmental regulations in low pressure boiler operations.
