Furnace oil is a Dark, viscous residual fuel oil which is obtained by blending residual products from refining processes with suitable diluent usually middle distillates to obtain the required fuel oil grades. These fuel oil grades are similar in nature and have been marketed under different specifications in various countries.
USES OF FURNACE OIL ARE
- As fuel for Power Generation in DG Sets
- As fuel for Boilers/ Furnaces/ Air pre-heater/ Any other Heaters
- Fuel for
Furnace oil is a class C product having Flash Point above 66 deg C. Since this is a residual fuel, there has to be gradual filtration system to prevent the filter choking and fuel nozzles choking. Due to its viscous nature, it has to be heated to improve its flow ability and to a proper temperature for proper atomization. Normally gear pumps are preferred to avoid cavitation problems.
