What is the key function of a fuel oil system?

The key function of a fuel oil system is to supply fuel oil at the correct temperature and pressure. This is crucial for efficient combustion in a steam boiler or engine. For the combustion process to be effective, the fuel oil must be delivered in a specific manner that optimizes its burn characteristics.

When fuel oil is maintained at the correct temperature, it flows more easily, ensuring that the combustion process is smooth and consistent. Pressure also plays a vital role in atomizing the fuel for better mixing with air, leading to more efficient burning. If the temperature or pressure is not within the ideal range, it can lead to incomplete combustion, higher emissions, and reduced efficiency.

While filtering impurities from the oil, storing excess fuel oil, and mixing fuel oil with water are relevant tasks related to fuel management and preparation, they do not encompass the primary objective of the fuel oil system, which is focused on providing fuel at optimal conditions for combustion.
