System and method for controlled fuel blending in gas turbines

摘要

A system includes a gas turbine engine having a combustor, and a fuel blending system. The fuel blending system further includes a first fuel supply configured to supply a first fuel, a second fuel supply configured to supply a second fuel, a first fuel circuit, a second fuel circuit, and a controller. The first fuel circuit may be configured to blend the first fuel and the second fuel to form a first to form a first fuel mixture. The second fuel circuit may be configured to blend the first fuel and the second fuel to form a second fuel mixture. The controller may be configured to regulate blending of the first fuel mixture and the second fuel mixture based on a measured operating parameter of the combustor.

1. A system, comprising:
a gas turbine engine comprising a combustor; and a fuel blending system, comprising:
a first fuel supply configured to supply a first fuel;a second fuel supply configured to supply a second fuel;a first fuel circuit configured to blend the first fuel and the second fuel to form a first fuel mixture, wherein the first fuel mixture has a first blending ratio of the first and second fuels;a second fuel circuit configured to blend the first fuel and the second fuel to form a second fuel mixture, wherein the second fuel mixture has a second blending ratio of the first and second fuels; anda controller configured to regulate blending of the first fuel mixture and blending of the second fuel mixture simultaneously, wherein the controller is configured to regulate blending based on a measured operating parameter of the combustor, and wherein the controller is configured to simultaneously regulate the blending of the first blending ratio to be different from the blending of the second blending ratio.
