1. A method of blending at least two fuels, the method comprising:
providing at least two fuels to a helical static mixer via a fuel supply system, the fuel supply system including a fuel supply circuit for each fuel of the at least two fuels, the fuel supply circuit including a main fuel supply line, a recirculation line extending from an inlet on the main fuel supply line and an outlet on the main fuel supply line, and an atmospheric vent line extending from the main fuel supply line between the inlet and the outlet;
mixing, via a plurality of helical structures of the helical static mixer, the at least two fuels to form a fuel mixture;
determining, via one or more sensors, a measured interchangeability index of the fuel mixture, the interchangeability index being one of a measured Wobbe Index of the fuel mixture or a measured Modified Wobbe Index of the fuel mixture;
comparing the measured interchangeability index to a predetermined interchangeability index;
adjusting, via the fuel supply system, one or more parameters of at least one of the at least two fuels based on the comparison between the measured interchangeability index and the predetermined interchangeability index; and
providing the fuel mixture to a combustion system.
