HFO (Heavy Fuel Oil)

HFO is a heavy black residual fuel designed specifically for use in high heat release applications such as furnaces for various industrial processes, boilers as a source of energy for the generation of steam, as well as for large, slow speed compression ignition engines as found in marine or stationary units. Areas of use include mines, power plants, manufacturing plants etc.

It complies with the latest version of South African National Standards (SANS 1314).

Benefits include:

  • It has high calorific value which makes it suitable for high energy demand activities.
  • Readily stored – occupies half the space of coal for equivalent heat content.
  • Easily handled, regulated and controlled.
  • Less maintenance than coal-fired equipment.
  • Less labour required than with coal, no stoking, ash removal or conveyors required.
  • Less capital expenditure than equivalent coal plant.
  • Clean operation – no fly ash or dust problems, easy smoke control.
  • Longer furnace and boiler fire; less depreciation.
