Furnace Oil

What is it?

Furnace Oil is a dark viscous residual fuel obtained from crude distillation.  Bunker Oil and Fuel Oil are the other names for Furnace Oil. Viscosity is the most important characteristic in Furnace Oil specification.  It influences the degree of pre-heat required for handling, storage and satisfactory atomization.  180 Cst  grade is Bunker Fuel with max viscosity of 180 Centistokes (Thinner). 380 cst grade is Bunker Fuel with max viscosity of 380 Centistokes (Thicker).

It is used primarily for steam boilers in power plants, aboard ships, and in industrial plants for boilers and furnaces. Commercial fuel oils usually are blended with other petroleum fractions to produce the desired viscosity and flash point.
