Systems for supplying liquid fuel emulsion to a combustion system of a gas turbine

An electricity generation system comprising:

• a combustion system;
• and
• a liquid fuel supply system comprising at least one storage tank for liquid fuel capable of supplying a liquid fuel to at least one nozzle connected to a combustion chamber of the combustion system, the liquid fuel supply system comprising a first piping section disposed downstream of the at least one tank and a second piping section disposed downstream of the first piping section and upstream of the at least one nozzle, the first piping section having a first line that includes a pressurizing means and an injection point of water disposed downstream of the pressurizing means, the water and the liquid fuel forming a mixture within the first line downstream of the injection point;
• wherein the second piping section comprises a first mixing device, wherein the first mixing device is configured to create an emulsion and spread an emulsion flow to at least one piping connected to the at least one nozzle;
• wherein a second mixing device is disposed on the first line downstream of the injection point and upstream of the first mixing device such that all of the mixture travels through the second mixing device before entering the first mixing device;
• and
• wherein the second mixing device is configured to provide an input flow rate regime to the first mixing device having a Reynolds number greater than or equal to 2000 such that a variability of a concentration of the water in the mixture is at maximum +/−30% between each piping in the at least one piping.
