Assumptions for calculating OM


Fuel Type
    (kg-CO2/TJ) Fuel Net Calorific Values (kCal/kg) Specific Gravity (kg/litre) Fuel Net Calorific Values (kJ/litre)
Fuel Oil (LFO/ HSFO 180 CST ) 75,500 10,200 0.96 40,989.25
Coal 92,800 6,300 0.00
LSFO 180 CST 75,500 10,200 0.96 40,989.25
Residual Fuel (LHF/HSFO 380 CST ) 75,500 10,300 0.96 41,391.10
Diesel (LAD) 72,600 10,556 0.86 37,985.15
Naphtha 69,300 11,491 0.68 32,542.29

1.00kCal = 4.1868kJ


Calorific values of fuels were obtained from the specifications published by the Ceylon Petroleum Corportation
