Calculating the Specific Fuel Consumption
Use the equation that is in Table 2 to calculate the Specific Fuel Consumption.
Table 2
Equation For Calculating the Specific Fuel Consumption
F × D = SFC
ekW-hr
F is the liters of fuel that have been burned.
D is the density of the fuel. The density is expressed in grams per liter.
ekW-hr is the electrical kilowatt hours that were produced with the fuel.
SFC is the specific fuel consumption.
Table 3 is an example for using the equation that is in Table 2. The data in the example assumes the following conditions:
During this operation, the engine used 18440 L (4872 US gal) of fuel.
The density of the fuel was 987 gm per liter.
The operation generated 88 800 ekW.
Table 3
Example of the Equation for Calculating the Specific Fuel Consumption
18 440 × 987 g/L × 1 = 205g
88 800 ekW-hr L ekW-hr Calculating the Heat Rate
The specific fuel consumption must be determined before the heat rate can be calculated. Use the equation that is in Table 4 to calculate the heat rate.
Table 4
Equation For Calculating the Heat Rate SFC × LHV = HR
SFC is the specific fuel consumption.
LHV is the low heat value of the fuel.
HR is the heat rate.
Table 5 is an example for using the equation that is in Table 4. The data in the example assumes the following conditions:
The specific fuel consumption is 205 gm per ekW-hr.
The LHV of the fuel is 42 000 KJ per kilogram.
Table 5
Example of the Equation for Calculating the Heat Rate
205 g × 42 000 kJ × kg = 8608 kJ
ekW-hr kg 1000 g ekW-hr The equation in Table 6 includes a conversion factor for calculating BTU from kJ. The data is from the example in Table 5.
Table 6
Conversion of kJ From the Heat Rate to BTU
8608 kJ × 1 BTU = 8159 BTU
ekW-hr 1.055 kJ ekW-hr Monitoring the Trends of Oil Consumption
The consumption of lube oil depends on the following factors:
Engine load
Hours of operation
Type of oilMonitor the engine oil consumption by calculating the Specific Oil Consumption on a daily basis. The following conditions can produce misleading data on oil consumption:
Improper operation of the lube oil centrifuge
Inaccurate measurement of additions of oil
Leaking of lube oil
Overfilling of the oil sumpTo measure additions of oil accurately, use a meter to monitor additions of oil at the engine. Also, check the total oil consumption against the delivery of oil.Calculating Specific Oil Consumption
Use the equation that is in Table 7 in order to calculate the Specific Oil Consumption.
Table 7
Equation For Calculating the Specific Oil Consumption
O × D = SOC
ekW-hr
O is the liters of oil that have been consumed.
D is the density of the oil. The density is expressed in grams per liter.
ekW-hr is the electrical kilowatt hours that have been produced during consumption of the oil.
SOC is the specific oil consumption. Table 8 is an example for using the equation that is in Table 7. The data in the example assumes the following conditions:
The engine consumed 66 L (17.4 US gal) of oil during the
