Claim 15:
16. A method according to claim 15, wherein the net specific energy is computed using the following formula:

QRnp=(C−Aρadj2+Bρadj)[1−a(ww+wa+ws)]+bws−cww,

where ρadj denotes the temperature-adjusted fuel density at the reference temperature of 15 degrees Celsius (in kilograms per cubic meter), ww denotes the water content of the fuel (as a mass percentage), wa denotes the ash content of the fuel (as a mass percentage), ws denotes the sulphur content of the fuel (as a mass percentage), and where A, B, C, a, b and c denote respective predefined constant values.
