Fuel Oil Calculation Program

Fuel Oil Calculation

By Lars Josefsson

Heavy Fuel Oils, HFO, consist largely of residues from crude oil refining. These residues are blended with suitable gas oil fractions in order to achieve the viscosity required for convenient handling. Since the sulfur contained in the crude oil is concentrated in the residue material, heavy fuel oils sulfur level naturally is rather high. Furthermore, heavy fuel oils may contain large quantities of heavy metals such as nickel and vanadium and also sediments and water. For these reasons it is utmost important that the engineer easily can calculate the fuel oils appropriate operation temperature, its energy and its ignition quality.

Designed to help with the calculation necessary for the quantity measurement of oil products and for the efficient handling and use of heavy fuel oils. While intended principally for ships staff the Fuel Oil Calculation program should also be found useful by those ashore in ship owners' organizations, engine and equipment manufacturer, ship builder etc.
Also visit the Smoke density monitor page.

The basic idea with the Fuel Oil Calculation Program is that anyone should be able to easily get the most important informations about their fuel oil. The initial values are not default settings, but recently used values. In other words, the program will remember what you did last.

Enter what you know about your fuel your oil, viscosity, density, etc.
then enter the viscosity your burner should have and immediately you will get the temperature that you should set on the fuel oil preheater. You will also get the fuel oils CCAI, Specific energy and the normal m³ of air per kg of fuel for stoichiometric combustion.

Download the and place the files Fuels.exe and Fuels.cfg in the very same directory. This Windows program may be used free of charge.
