Light Diesel Oil (LDO) is a type of fuel derived from crude oil, typically used in various industrial applications, including generators, furnaces, and marine engines. It has a lower viscosity than heavy diesel oils and is often favored for its efficient combustion properties. Key Characteristics of LDO: Density: Lower density compared to heavier fuels, making it easier to pump and handle. Viscosity: Less viscous, which aids in atomization during combustion. Flash Point: Higher flash point than lighter fuels, making it safer to store and transport. Sulfur Content: Varies; lower sulfur content is preferred for environmental compliance. Applications: Power Generation: Often used in backup generators and power plants. Heating: Used in industrial and commercial heating systems. Marine: Used in ships and boats where larger engines are required. Environmental Considerations: LDO can emit pollutants when burned, so regulatory standards may apply, particularly concerning sulfur content and particulate emissions.
