Fuel system
The evermore intensive utilization of crude oils by modern processing is the reason the portion of
the residual oils (heavy fuel) has become smaller and the portion of the in the residual oils
remaining contaminating matter has, however, increased.
The distinguishing properties of such residual oils are their high viscosity and their density as well
as the increased portion of chemical compounds with sulphur, vanadium, sodium and cat fines etc.
The remainig contaminating matters influence the operation of the “heavy fuel engine”! Optimum
treatment of the fuel and an intensive supervision of the plant are therefore a precondition for
economical operation of “heavy fuel engines”.
