Fuel consumption calculation of a fuel and water mixture

A fuel control system (300) for fuel consumption calculation for a fuel and water mixture, the fuel control system (300) comprising:

• a mixer (330);
• a fuel source (310) fluidly coupled to the mixer (330), the fuel source (310) being configured to measure a flow of fuel to the mixer (330);
• a water source (315) fluidly coupled to the mixer (330), the water source (315) being configured to measure a flow of water to the mixer (330);
• a mixture flow meter (5) fluidly coupled to the mixer (330), the mixture flow meter (5) being configured to receive and measure properties of a fuel/water mixture from the mixer (330);
• and
• a controller (360) communicatively coupled to the fuel source (310), the water source (315), and the mixture flow meter (5), said controller (360) being configured to calculate a fuel consumption based on the measured flow of the fuel, the measured flow of the water, and the measured flow of the fuel/water mixture provided by the mixture flow meter (5);
• wherein the controller (360) being configured to calculate the fuel consumption based on the measured flow of the fuel, the measured flow of the water, and the measured flow of the fuel/water mixture comprises the controller (360) being configured to calculate the fuel consumption based on equation:

• where:
• SFOC=specific fuel oil consumption (g/kWh);
• OTEST=net calorific value of the fuel oil during test (MJ/kg);
• OCONT=net calorific value of the fuel oil during the engine's baseline characterization (MJ/kg), which may be referred to as factory acceptance test;
• α=power adjustment factor;
• K=ratio of indicated power;
• Be=fuel oil consumption on test bed (g/kWh);
• and
• EDP=Engine driven pumps (g/kWh).
