Fuel treatment
Types of fuel
- Distillate fuels
- Residual fuels
Distillate fuels
Fuels which are free flowing , easily to store and can be used without further treatment
Application: turbine plants, high and medium speed diesel engines
Residual fuels
Very viscous or thick at normal temperatures , and require hearing before use
Applications: slow-speed and some medium-speed diesel engines
Treatment of Fuel Oil and Lubricating Oil
- Fuel oil and lubricating oil require treatment before passing to the engine
- This will involve separation as a means of removing impurities from a fuel
Separation
Used to:
- Separate two liquids, for example oil and water,or
- Liquid and solids as in contaminated oil
Advantages:
- The separations of impurities and water from fuel oil is essential for good combustion
- The removal of contaminating impurities from lubricating oil will reduce engine wear and possible breakdowns
Methods separate:
- Gravity in a settling tank
- Centrifuging the fuel
