Light diesel oil, or LDO, is a blend of components from the distillation process of crude. It is used in engines with an rpm less than 750, such as boilers and furnaces. LDO is also referred to as distillate fuel or marked oil.
Light diesel oil is used as fuels in many applications :
- Boilers
- Furnaces
- Air pre-heaters
- Lower RPM engines
- Lift irrigation pump sets
- Fertilizer plants
- Bunker
- DG set
