Abstract: Liquid fuel systems and methods are provided. A liquid fuel system includes a mixing unit and a plurality of liquid fuel supply systems. Each liquid fuel supply system is fluidly coupled to the mixing unit. The liquid fuel system further includes a controller communicatively coupled to the mixing unit and the plurality of liquid fuel supply systems. The controller includes memory and one or more processors. The memory stores instructions that when executed by the one or more processors cause the liquid fuel system to perform operations including providing one or more liquid fuels from the plurality of liquid fuel supply systems to the mixing unit. The operations further include mixing, with the mixing unit, the one or more liquid fuels to create a liquid fuel mixture. The operations further include providing the liquid fuel mixture to a combustion section of a turbomachine.

Abstract: A method includes delivering fuel and a first portion of oxidant as a rich mixture to the first zone of the combustion chamber. The fuel includes ammonia (NH3). The method further includes burning the rich mixture in the first zone. Combustion gases containing nitrogen oxides (NOx) are produced. The method further includes delivering a second portion of oxidant into the second zone to break down unburned ammonia into ammonia intermediates in the second zone. The nitrogen oxides (NOx) are consumed by reacting with the ammonia intermediates in the second zone. Byproduct hydrogen is produced as a result of breaking down the unburned ammonia into the ammonia intermediates. The method further includes delivering a third portion of oxidant into the third zone. The byproduct hydrogen is burned in the third zone. The third portion of oxidant is greater than the first portion of oxidant and the second portion of oxidant.
