Combustor fuel supply assembly and related method

A system includes a turbine fuel supply system (40). The turbine fuel supply system includes a first turbine fuel mixer (52) configured to mix a first liquid fuel (42) and a first deaerated water (15) to generate a first fuel mixture. The first fuel mixture is configured to combust in a combustor (16) of a gas turbine engine (10). The turbine fuel supply system also includes a deaerated water flow path (70) configured to route the first deaerated water (15) to the first turbine fuel mixer (52) and a liquid fuel flow path configured to route the first liquid fuel to the first turbine fuel mixer (52).
